Highest temperature in NYC on July 3?

Platform comparison

Market context

The underlying event is the highest temperature recorded at New York’s LaGuardia Airport on 3 July 2026, measured in degrees Fahrenheit and sourced from Wunderground. Current crowd-implied probability of 0% YES suggests the market expects the temperature to fall outside the specified range, yet historical data shows July 3 has produced extreme heat: LaGuardia hit 107°F on 3 July 1966, and Newark reached 105°F on the same date [5][8]. Recent 2026 data confirms LaGuardia’s July highs are forecast between 81°F and 99°F, with overnight lows from 68°F to 83°F, and a record warm midnight of 94°F recorded early Friday [2][1]. This pattern indicates that while 107°F is unlikely, temperatures near 94–99°F remain plausible, making the 0% probability potentially premature if the range includes values above 95°F.

Traders should monitor daily high forecasts from AccuWeather and real-time updates from Wunderground, especially as heatwaves intensify in the Northeast. A recent Yahoo News report highlights dangerous, record-breaking heat possible across New York and New Jersey, with multiple airports already reaching 90–100°F on 2 July [3][8]. Key dependencies include the timing of the settlement window (ending 12:00 UTC on 3 July 2026) and the reliability of Wunderground’s data feed. Regulatory accessibility is shaped by German GlüStV provisions, US CFTC oversight, and the “no-KYC up to $1,500” threshold, which allows traders to access this market without identity verification if stakes remain under that limit—enhancing participation for those prioritising privacy while staying within legal bounds.
