Highest temperature in NYC on August 13?

Platform comparison

Market context

The highest temperature recorded at LaGuardia Airport on 13 August 2026 will determine this market's outcome. Resolution hinges on the Daily Observations table in Weather Underground's historical data, not the Day High & Low summary section—a distinction that matters when hourly readings diverge from daily aggregates. The settlement window closes at midday UTC on that date, meaning afternoon temperature spikes after the window closes will not affect the final resolution.

New York's August heat patterns show median highs around 82–84 °F, with extreme readings occasionally exceeding 95 °F during heat waves. The 0% crowd probability reflects either confidence in moderate conditions or sparse trading volume at market inception. Historical August temperature ranges at LaGuardia span from lows near 65 °F to records above 100 °F; the specific range brackets in this market will determine which outcomes traders are positioned for. Comparable weather markets on prediction platforms typically see probability shifts only when meteorological forecasts update substantially, usually 7–10 days before the event.

From a regulatory standpoint, this market's accessibility depends on jurisdiction and operator licensing. Under German GlüStV rules, prediction markets require state approval; US CFTC oversight applies to derivatives-like contracts on US weather indices, though small-stake prediction markets often operate in grey zones. Many platforms offer no-KYC trading up to $1,500 cumulative exposure, meaning traders can participate without identity verification below that threshold—a feature that affects liquidity and entry barriers for this specific contract. Traders should verify their local regulatory environment before positioning, particularly in EU member states where gambling and financial licensing overlap.
