How can a seasonal business protect its revenue from bad weather?

The Crux Team · Published October 7, 2026 · Updated October 7, 2026

Business interruption insurance usually pays only when weather causes physical damage, so a rainy season that just keeps customers away is usually not covered. To protect revenue from the weather itself, a seasonal business can use parametric weather insurance or weather event contracts. Both pay on an agreed measurement, such as rainfall at a local station, and neither needs a loss adjuster. Cash reserves are another option. Each has a cost, and measurement-based options don’t pay your exact loss.

What are your options?

Option	What it covers	How it pays	What you pay upfront	Main limit
Business interruption insurance	Lost income while you can’t operate after physical loss or damage from a covered cause, such as a storm that damages your building.	You file a claim and document the lost income. The insurer reviews it and pays under the policy.	An insurance premium. Coverage is often part of a business owner’s policy or a commercial property policy.	Usually no payout for a wet or cold season that keeps customers away but damages nothing.
Parametric weather insurance	An agreed weather measurement, such as heavy rainfall or an unusually warm winter, at an agreed place and time.	The insurer pays a set amount when an independent measurement meets the trigger. There is no loss adjustment.	An insurance premium, based on the payout and how likely the trigger is.	Not widely available yet. The fixed payout may not match your actual loss.
Event contracts set up by Crux	Weather that can be measured, such as rainfall, snowfall or temperature, over a single day or a full season.	The payout follows the agreed weather measurement. There are no loss adjusters.	An upfront cost. You see it before you approve anything.	Pays on the agreed station and dates, which may not match your actual lost sales.
Buying weather event contracts yourself on an exchange	Weather contracts listed on CFTC-regulated exchanges, such as monthly snowfall at a named station or degree-day futures for a named city.	The exchange settles each contract under its published rules and named data source.	The contract price, plus fees.	Only listed places, dates and thresholds are available. You choose, buy and manage the contracts yourself.
Cash reserves	Any shortfall, from any cause, up to the amount you have set aside.	You draw on your own savings when sales fall short.	No premium. Cash you set aside can’t be used for other things.	A very bad season, or two in a row, can use up the reserve.
Do nothing (absorb the loss)	Nothing.	Nothing. The business carries the full shortfall.	Nothing.	A bad season falls fully on your cash flow, payroll and debt payments.

Does business interruption insurance cover lost sales from weather?

Usually not, unless the weather damages your property. Business interruption insurance, also called business income insurance, protects against lost income while a business is closed after a covered event, such as a fire, causes physical property damage, the NAIC says. These policies generally require the losses to be caused by physical damage to the property, the Insurance Information Institute says.

State insurance regulators ran a data call in 2020 on nearly 8 million commercial policies with business interruption coverage. Preliminary results showed that 98% required physical loss, according to the NAIC.

So a storm that tears off your roof and closes the shop may be covered. A cold, wet June that keeps customers at home usually is not, because nothing was damaged. Coverage may be part of a business owner’s policy, a commercial property policy or a package policy, the NAIC notes. Ask your agent what your policy covers and what it excludes.

What is parametric insurance?

Parametric insurance pays a set amount when a measured event happens. You don’t prove a loss. The NAIC defines it as a contract that pays a set amount based on the magnitude of a specific event. The contract names the payout, the measurement and the third party that confirms the trigger.

For weather, the trigger is a measurement at an agreed place and time. Insurance Business gives the example of a retailer whose sales fall because of excessive rainfall or an unusually warm winter. Unlike traditional coverage, a parametric policy needs no physical damage and no claims adjuster.

California’s Assembly Insurance Committee also lists the limits. A payout may not cover the full loss, parametric policies are not widely available, and premiums may be higher because of distribution and capacity costs. It says a parametric policy generally should not be your only coverage.

Weather event contracts also pay on a measured weather outcome. They are bought and sold on CFTC-regulated exchanges. See parametric insurance vs event contracts for a side-by-side comparison.

How fast is the payout?

It depends on how the payout is decided.

Business interruption insurance pays after a claim. You document the lost income, and the insurer reviews it. For disaster losses, payment under a standard indemnity contract can take months or years, the NAIC says.
Parametric insurance skips the loss adjustment. The same NAIC page says payment can be made in a matter of weeks.
Event contracts set up by Crux: a payout follows the agreed event, so there’s no claims process.
Event contracts you buy yourself pay when the contract settles. The exchange’s rules, filed with the CFTC, set the data source and the settlement date, as in one Kalshi weather filing.

Can a business hedge the weather with event contracts?

Yes, within limits. Event contracts have a fixed payout and an expiration, and they can be used to hedge real-world risks, according to the CFTC, the federal regulator for these markets. Its example is a citrus farmer who buys a weather event contract against losses from a sudden freeze.

Weather contracts are listed on CFTC-regulated exchanges. For example, Kalshi, a CFTC-registered designated contract market, filed a contract with the CFTC on monthly new snowfall at a named weather station, as reported by the National Weather Service. CME Group has listed heating and cooling degree-day futures since 1999, with CFTC approval, according to CME Group. A business can buy these contracts itself. It then chooses, buys and manages the contracts through its own account.

Crux offers a second route. You tell us what could hurt the business. We set up the protection and show you the terms and price. You approve it through an account in your business’s name that we help you open. Crux arranges exchange-traded contracts. Crux is not an insurer or counterparty.

Tell us which weather hurts your business, and we’ll confirm what we can protect.

A worked example

Extra rain days eat into your job margin. Your schedule can absorb 12 rain days. Protection pays for each rain day beyond that.

If April to June brings	Contract payout	What it means
10 rain days	$0	There is no payout. The $18,000 protection cost still applies.
17 rain days	$75,000	Helps carry payroll through 5 extra rain days.
22 rain days	$150,000	Helps carry payroll through 10 extra rain days.

Protection cost: $18,000 upfront

Using the agreed local weather station. Illustrative example. Terms and pricing agreed upfront.

What are the limits?

If the agreed event doesn’t happen, the contract doesn’t pay out, and the upfront cost isn’t returned.
The agreed event may not match your actual loss. A contract pays on the measured outcome, not on your own costs or sales. This gap is called basis risk.
The payout follows the contract terms and the agreed measurement source, such as a published price or a named weather station.
Protection pays on the agreed weather at the agreed station and dates. A slow season with normal weather does not trigger a payout.
Weather protection that pays on a measurement does not replace property insurance. Keep cover for physical damage to buildings and equipment.
Not every type of weather, place or season can be covered. Tell us what could hurt the business, and we’ll confirm what we can protect.

When is Crux not a fit?

Your main weather risk is physical damage to your building or equipment. Property and business interruption insurance are made for that.
Your sales don’t follow a weather measurement, such as rain days or temperature at a nearby station.
A bad season would cost less than you can comfortably absorb from cash reserves.
You want to choose and manage contracts yourself, and a listed exchange contract matches your location and dates.
