Highest temperature in NYC on July 20?

Platform comparison

Market context

On 20 July 2026, the highest temperature recorded at LaGuardia Airport in New York City will determine the outcome of a weather prediction market, with settlement based on Wunderground’s daily maximum in degrees Fahrenheit. The event is now complete, as today is 21 July 2026, and historical records confirm the day’s peak heat has already been logged.

Historical July temperatures at LaGuardia typically range between 75°F and 90°F, with 82–83°F representing a common mid-range peak during stable summer conditions. The current crowd-implied probability of 0% for any outcome outside the 82–83°F band aligns with this pattern, as that range now holds 100% market confidence, suggesting the observed temperature fell squarely within it [1]. Comparable years show similar clustering, reinforcing that extreme outliers below 69°F or above 90°F are rare in this window.

Traders should monitor official National Weather Service archives and Wunderground’s daily updates for LaGuardia to confirm the exact figure, as these are the designated resolution sources [2]. While no new announcements are expected post-settlement, the speed of data publication from these platforms affects how quickly funding flows translate into book depth. For users on polymarket-klarna.co.uk, the frictionless Klarna on-ramp and SEPA/USDC withdrawal rails ensure that capital can move swiftly into weather-linked positions, directly influencing liquidity as outcomes near resolution.
