Highest temperature in NYC on August 15?

Platform comparison

Market context

On 15 August 2026, the highest temperature recorded at LaGuardia Airport Station will fall within one of several defined ranges. Resolution will depend on the Daily Observations table from Weather Underground, not the summary Day High & Low figures, establishing a precise measurement standard that eliminates ambiguity between different reporting methodologies. The settlement window closes at 12:00 UTC on that date, meaning final temperature readings must be confirmed by that deadline.

Historical August temperatures at LaGuardia show a median high near 27–28°C (81–82°F), with extreme highs occasionally reaching 32°C (90°F) or above during heat waves. The 0% crowd probability suggests traders perceive the current market structure as offering poor odds relative to expected outcomes, though this reflects sentiment rather than meteorological impossibility. August heat in New York varies significantly year-to-year; the National Weather Service records from 2012 and 2016 documented multiple days exceeding 32°C, whilst cooler Augusts have remained in the mid-20s Celsius range.

Traders monitoring this market should track seasonal forecasting updates from NOAA and the Climate Prediction Center, typically issued 6–8 weeks before August. Atlantic hurricane activity and upper-atmosphere pressure patterns in July 2026 will signal whether high-pressure systems favour sustained heat or cooler maritime influence. The regulatory framework for this market depends on jurisdiction: UK traders face no specific KYC requirement below £1,200 equivalent under Gambling Commission guidance, whilst US participants fall under CFTC oversight if the platform operates as a designated contract market. German traders should verify GlüStV compliance with their local regulator, as prediction markets remain subject to state-level licensing requirements.
