Highest temperature in NYC on August 16?

Platform comparison

Market context

On 16 August 2026, the highest temperature recorded at LaGuardia Airport will settle this market according to Weather Underground's Daily Observations table, the primary resolution source should any discrepancy arise with the Day High & Low summary. The settlement window closes at 12:00 UTC that day, meaning traders must account for the full calendar date's observations before final resolution. Current crowd pricing reflects 0% probability, suggesting the market perceives either extreme confidence in a specific temperature band or insufficient liquidity to establish meaningful odds.

Historical August temperatures at LaGuardia show a median high around 82–84°F, with extremes ranging from 96°F (recorded in 2021) to lows near 70°F during cooler years. The 0% crowd probability likely anchors to a particular temperature threshold rather than indicating genuine impossibility; examining comparable August settlement markets reveals that crowd-implied extremes often reflect boundary conditions rather than meteorological implausibility. Recent summers have produced occasional heat waves—the Northeast experienced elevated temperatures in July 2024—but August 2026 forecasting remains contingent on seasonal patterns and any anomalous atmospheric conditions.

From a regulatory standpoint, this market's accessibility depends on jurisdiction and platform licensing. Under German GlüStV frameworks, prediction markets operating without explicit sports-betting classification face stricter oversight, whilst US CFTC reach typically exempts small-notional weather derivatives. Platforms offering no-KYC access up to $1,500 notional exposure generally treat weather markets as exempt from enhanced customer verification, though this threshold applies per transaction or account depending on the operator's compliance interpretation. Traders should verify their platform's specific regulatory posture before positioning.
