How Does a Hurricane Affect Coffee Quality and Supply? What Hawaii's Kona and Ka'u Farms Face After Lala

Hurricane Lala made landfall on the southern tip of Hawaii Island on August 15, 2026, delivering the third-highest rainfall total ever recorded from a tropical cyclone in Hawaii's history — with some areas receiving over 20 inches and peak accumulations hitting 43 inches — and triggering a multi-year crisis for the state's coffee industry that will reshape supply, pricing, and buyer relationships well beyond the 2026 harvest.

The storm is the first to strike Hawaii Island directly since the late 1800s. It arrived at the single worst point in the annual agricultural calendar: the very beginning of harvest season, when ripe coffee cherries are ready to be picked and farms are gearing up for their most economically critical weeks of the year.

What exactly happened to Hawaii's coffee farms during Hurricane Lala?

Hurricane Lala passed just south of Hawaii Island on August 15, 2026, bringing extreme rainfall, flooding, and destructive winds to the island's southern districts. The Ka'u district — home to approximately 500 acres of coffeelands worked predominantly by smallholder farmers — bore the brunt of the storm's agricultural impact.

The deluge prompted a flash-flood emergency across Ka'u. Roads and bridges washed out. Water systems were damaged. Some communities were completely isolated, requiring food and essential supplies to be helicoptered in. For coffee farms, this meant that even growers whose trees survived the storm had no way to reach their land, let alone export anything they might salvage.

The Hawaii Coffee Association confirmed to Hawaii Public Radio that growers in Ka'u, Wood Valley, and Miloli'i were among the hardest hit, while some farms farther north around Holualoa — closer to the better-known Kona belt — reported losing 20% or more of their coffee trees when larger canopy trees toppled onto coffee plantings.

At Miranda's Farms, a Ka'u operation spanning roughly 80 acres, co-owner Maria Miranda told Hawaii Public Radio that hundreds of coffee trees had already been confirmed lost — uprooted, crushed by falling trees, or stripped bare of both limbs and fruit. At A Coffee Farm in Pahala, co-owner Alla Kostenko told SFGATE that thousands of trees were down or washed away across the farm's properties, with approximately half the trees at one site destroyed — mostly younger plantings that had not yet reached full productive maturity.

Rusty's Hawaiian, a Ka'u producer and roaster with a loyal following among specialty coffee buyers, announced on its website that it was forced to pause all roasting and shipping after the storm destroyed both its power supply and the transportation infrastructure it depends on to move product.

As of August 24, nearly 70 farmers and ranchers statewide had self-reported more than $3.2 million in Hurricane Lala losses across approximately 320 acres through the Hawaii Agriculture Disaster Response dashboard. Nearly $2 million of that reported damage was concentrated on Hawaii Island. Those figures are expected to climb significantly as access improves and more growers are able to assess their land.

Why does harvest timing make hurricane damage so much worse for coffee?

The timing of Hurricane Lala is not incidental — it is central to understanding why the damage will reverberate for years rather than just one season.

Hawaii's coffee harvest window typically opens in late summer or early fall, when cherries ripen and must be picked within a narrow timeframe to preserve quality. Miss that window, and the fruit either drops, ferments on the tree, or is destroyed by weather. There is no second chance within the same crop year.

Shawn Steiman, a Hawaii-based coffee scientist, consultant, and owner of Grok Coffee, explained the physics of the problem clearly: "The removal force for a ripe cherry is much lower than for a green cherry," he told Daily Coffee News. In practical terms, the cherries most ready to be harvested — the ones with the highest market value — were also the most vulnerable to being stripped off trees by wind and rain. Green, unripe cherries hold on more tightly to the branch and were more likely to survive. The crop closest to generating revenue was the crop most likely to be lost.

Alla Kostenko of A Coffee Farm articulated the same fear to Sprudge: the ripe cherries ready to be picked were washed away along with the trees, meaning there is no crop to harvest at all from the most affected plots.

Steiman also noted that significant defoliation of surviving mature trees could reduce future production by limiting photosynthesis and the trees' ability to generate new fruit, flowers, and leaves. A tree that loses most of its canopy in August may not produce a full crop the following year either — compounding the financial hit across multiple seasons.

How does a hurricane physically damage coffee trees and affect cup quality?

A hurricane's impact on coffee quality operates across three distinct layers: physical tree damage, crop loss, and infrastructure disruption — each of which affects the final cup in different ways.

Physical tree damage ranges from complete uprooting (which kills the tree entirely) to broken limbs, bark damage, and defoliation. Uprooted trees must be replaced, a process that typically takes three to five years before a new plant reaches meaningful production. Broken limbs reduce the canopy available for photosynthesis and the number of fruiting nodes available in subsequent seasons. Even trees that appear structurally intact after a storm may have suffered root damage from soil erosion or waterlogging that affects their long-term health.

Crop loss at harvest time is the most immediately visible damage. Ripe cherries stripped from trees by wind are lost entirely — they cannot be recovered from the ground in usable condition after being mixed with floodwater, debris, and soil. Cherries that remain on damaged trees but are bruised or partially fermented during the storm will produce defective green coffee with off-flavors. For a premium origin like Ka'u, where cup quality commands significant price premiums over commodity coffee, even a small percentage of defective beans can affect the reputation of an entire lot.

Infrastructure disruption affects quality in a less obvious but equally serious way. Coffee cherries that are picked must be processed quickly — typically within 24 hours for washed coffees — to prevent fermentation from degrading quality. When roads are washed out and processing facilities lose power, as happened across Ka'u after Lala, there is no way to move harvested cherry to wet mills or dry mills in time. Cherries that cannot be processed become unusable, even if they were picked in perfect condition.

Steiman also flagged seedling loss as a critical long-term concern: "I think the biggest damage is seedlings being uprooted or washed out, or cherries being ripped off and, of course, not having access to get to your farm, even just by foot." Seedlings represent future production capacity — their loss is an investment in years of labor and capital that cannot be quickly recovered.

What does this mean for Ka'u coffee supply and prices going forward?

Ka'u is a coffee-growing district on the southernmost tip of Hawaii Island, encompassing approximately 500 acres of coffeelands worked mostly by smallholder farmers. While Kona is the more globally recognized Hawaiian coffee region, Ka'u has built a strong reputation in specialty coffee circles over the past two decades for producing high-scoring, distinctive lots that command premium prices.

The supply implications of Hurricane Lala play out across multiple timescales.

In the immediate term — the 2026 harvest — many farms will produce little or nothing. Trees that were uprooted are gone. Ripe cherries that were stripped or washed away cannot be replaced within the season. Farms that lost access roads have no way to conduct harvest operations even if trees survived. The 2026 Ka'u harvest will almost certainly be dramatically smaller than in a normal year, and what coffee is produced may carry higher defect rates if processing infrastructure was compromised.

In the medium term — the 2027 and 2028 harvests — production will depend on how quickly surviving trees recover from defoliation and structural damage, and how rapidly destroyed trees can be replaced. Steiman's warning is direct: "If you've lost 10% of the trees you planted, then that reverberates to the future in a significant way. Not just yields, but the cost of replacing." New coffee trees typically take three to five years to reach full production, meaning trees planted in late 2026 or 2027 would not contribute meaningfully to harvests until 2029 at the earliest.

For buyers — whether specialty roasters, green coffee importers, or direct-trade partners — Ka'u coffee will be scarce and more expensive for several years. Farms that do have coffee to sell will be doing so from a position of financial stress, which creates both a risk (quality shortcuts under pressure) and an opportunity (buyers who commit to purchasing at fair prices provide critical liquidity).

Steiman's advice to green coffee buyers is worth quoting in full: "If there's a little coffee lying around, people need and want to sell it. People need money. They need to recuperate." He also cautioned that long-term commitment matters more than a single purchase: "If we've lost coffee, we've lost trade. People should be aware that helping means helping across time, not just in a moment, and that's true of any coffee area, any natural disaster."

What federal and state relief programs are available to Hawaii coffee growers?

The federal response to Hurricane Lala has been substantial in scope, though the translation of federal programs into actual cash for individual farmers involves a complex process of documentation, application, and approval.

President Trump approved Hawaii's request for a federal emergency declaration on August 25, covering Hawaii County, Maui County, and the City and County of Honolulu. This authorization unlocks Federal Emergency Management Agency support for affected communities.

For agricultural losses specifically, the most relevant programs come from the U.S. Department of Agriculture.

The Tree Assistance Program (TAP) is one of the most directly applicable tools for coffee growers — a USDA program that helps eligible commercial growers rehabilitate or replace perennial crop trees, including coffee, damaged by natural disasters. Applications generally must be filed within 90 days of the disaster or when the loss becomes apparent, making prompt action critical for Ka'u and Kona farmers. More information is available through the USDA Farm Service Agency.

The Emergency Conservation Program (ECP) can help pay for restoring farmland damaged by floods, hurricanes, and other disasters, including debris removal, grading or reshaping land, repairing permanent fencing, and restoring water-conservation structures. The University of Hawaii College of Tropical Agriculture and Human Resources (UH-CTAHR) announced that ECP applications related to Lala would open September 1. The program generally covers up to 75% of approved costs, subject to funding availability.

The USDA is urging affected growers to contact their local Farm Service Agency office as soon as possible to report losses and determine which programs apply. Growers with federal crop insurance should also report damage to their insurance agent immediately.

UH-CTAHR has assembled a Post-Hurricane Lala resource guide for Hawaii County growers that includes coffee-specific instructions and contacts for all relevant USDA programs.

What should affected coffee growers do right now to protect their recovery?

The single most important immediate action for any coffee grower affected by Hurricane Lala is thorough documentation — and the window to capture accurate damage evidence is closing as cleanup begins.

UH-CTAHR's post-hurricane resource guide recommends that growers photograph every category of damage: roads, buildings, irrigation and water systems, processing equipment, erosion, damaged or missing trees, fallen or unharvested coffee cherries, and stored parchment or green coffee. Cleanup labor should be documented, receipts saved, and historical production records preserved to support estimates of potential losses over the next three to five years.

This documentation serves multiple purposes. It supports applications for USDA programs like TAP and ECP. It provides evidence for crop insurance claims. And it creates a baseline for demonstrating the multi-year financial impact of tree loss — which is critical for programs that calculate compensation based on expected future production.

Beyond documentation, growers should:

Contact the USDA Farm Service Agency Hawaii office immediately to report losses and begin the application process for available programs.
Report any crop insurance claims to their agent as soon as possible.
Self-report losses through the Hawaii Agriculture Disaster Response dashboard if they have not already done so — this data is being used to quantify the statewide impact and advocate for additional resources.
Reach out to green coffee buyers and trading partners to communicate availability and needs. Farms that have salvageable inventory need to move it quickly.

How does this compare to other hurricane impacts on coffee-growing regions?

Hawaii is not the first coffee-producing region to face catastrophic hurricane damage, and the pattern of impacts — immediate crop loss, multi-year tree recovery, infrastructure disruption, and long-term supply contraction — is consistent across events.

Puerto Rico's coffee industry, which was already struggling before Hurricane Maria in 2017, lost an estimated 80% of its crop in that storm and saw production decline for years afterward. The recovery required sustained investment in replanting, infrastructure repair, and buyer relationships — a process that took the better part of a decade and is still ongoing in some areas.

Vietnam and other Asian coffee-producing regions have faced similar dynamics from typhoons, with the key variable being the timing of the storm relative to harvest and the age profile of the trees affected. Younger trees, as at A Coffee Farm in Pahala where roughly half the trees at one plot were lost and were described as predominantly younger plantings, take longer to replace and represent a greater proportional loss of future production capacity than mature trees.

The Ka'u situation is particularly acute because the region's coffee industry is built on smallholder farms — operations where the loss of even a portion of trees or one season's harvest can be financially existential. Unlike large commodity producers with diversified holdings and access to capital markets, Ka'u's farmers are largely dependent on each year's crop for their operating income. A single catastrophic harvest, compounded by the cost of replanting and infrastructure repair, can push small farms into debt or force them out of production entirely.

What can coffee buyers and consumers do to support Hawaii's recovery?

Steiman's framing — that support needs to extend across time, not just in a single moment — is the most useful framework for buyers and consumers thinking about how to respond.

For green coffee buyers and importers, the most direct support is purchasing available inventory at fair prices, even if volumes are smaller than usual and quality is more variable than in a normal year. Committing to purchase relationships for the 2027 and 2028 harvests — when recovering farms will need the certainty of a buyer to justify the investment in replanting and rehabilitation — is equally important.

For specialty roasters, transparency with customers about supply disruptions and price adjustments is both honest and commercially sensible. Consumers who understand why Hawaiian coffee may be scarcer and more expensive over the next few years are more likely to accept price increases and remain loyal to farms they know are recovering from a disaster.

For consumers, the simplest action is to buy Hawaiian coffee — from Ka'u, from Kona, from any of the island's growing regions — when it is available, and to pay the prices that reflect the actual cost of producing it in a high-cost, high-risk environment. Hawaiian coffee has always been expensive relative to commodity origins. The reasons for that premium — the cost of land, labor, and infrastructure in Hawaii, combined with the quality of the product — are now compounded by the cost of disaster recovery.

It is also worth noting that the Hawaii Coffee Association was still assessing the overall impact on the coffee sector as of late August 2026. The $3.2 million in self-reported losses across 320 acres is almost certainly an undercount, as many farmers had not yet been able to access their land. The full picture of what Hurricane Lala has done to Hawaii's coffee industry will take months to emerge — and the response from buyers and consumers over that same period will shape which farms survive to harvest again.

What is the long-term outlook for Ka'u and Kona coffee after Lala?

The honest answer is that the long-term outlook is uncertain, and anyone who tells you otherwise is guessing.

What is clear is that the 2026 harvest from the most affected areas will be severely diminished. What is less clear is the rate of recovery for surviving trees, the pace of replanting on farms that lost significant portions of their plantings, and the extent to which infrastructure — roads, bridges, water systems, processing facilities — can be restored in time to support the 2027 harvest.

The federal and state relief programs now being activated will help, but they are not instant. TAP applications must be filed within 90 days, approved, and then funded before growers receive any money. ECP applications open September 1 but will go through a review process before disbursement. The gap between when growers need cash and when programs deliver it is a real risk for farms operating on thin margins.

Steiman's multi-year framing is the right one: the reverberations of losing trees, losing a harvest, and losing infrastructure will be felt across the 2026, 2027, and 2028 crop years. Farms that lost younger plantings — like A Coffee Farm's hardest-hit plot — are looking at a three-to-five-year replanting cycle before those trees contribute meaningfully to production again.

For the specialty coffee world, Hurricane Lala is a reminder that origin is not an abstraction. The farms, the farmers, the infrastructure, and the ecosystems that produce distinctive coffees are physical and vulnerable. Ka'u's reputation for exceptional coffee was built over decades of careful cultivation. Rebuilding the capacity to produce that coffee after a storm of this magnitude will require the same sustained commitment — from growers, from buyers, and from the broader coffee community — that built it in the first place.
