Highest temperature in Los Angeles on July 22?

Platform comparison

Market context

The real-world event is the highest temperature recorded at Los Angeles International Airport on 22 July, measured in Fahrenheit by Wunderground’s daily history for KLAX. The current crowd price at 0% for Yes implies the market is already treating the outcome as effectively locked, so any late move would have to come from a fresh reading of the official history page rather than from weather forecasting alone.

That kind of pricing usually leaves little room for normal summer volatility, because the answer is determined by a single station reading rather than a citywide average. In Los Angeles, late-July heat can still spike intraday, and local reporting on recent heat waves has repeatedly highlighted the operational knock-on effects: power-use warnings, cooling centres, and advice to avoid peak-afternoon loads.[3] But for settlement, the relevant point is not general heat risk; it is whether KLAX posts a temperature that falls into the market’s listed range before the window closes.

For traders, the main catalysts are administrative rather than meteorological: the Wunderground history entry itself, any delay in how the day’s high is updated, and whether the final Fahrenheit/Celsius setting is interpreted consistently with the market bands. Because this is a payment-sensitive venue, the book depth behind the price will also track how easily participants can add funds and exit; deposits via Klarna or SEPA tend to support broader retail participation, while USDC rails can speed flows for users who already hold on-chain balances. Where on-ramp friction is low, these small weather markets often stay better populated after the first rush, but when funding takes time, liquidity can thin quickly once the headline outcome looks near-certain.
