Highest temperature in NYC on July 22?

Platform comparison

Market context

The event is the **highest recorded temperature at LaGuardia Airport on 22 July 2026**, as published by Wunderground, and the market will not settle until the next day’s first data point appears on the source page.[1] For a summer New York day, the relevant reference point is not the forecast headline but the actual daily high at KLGA, which is what determines the payout.[1]

A 0% implied YES price suggests the market is currently treating the outcome as effectively unavailable rather than forecasting a cold day. July in New York City is typically warm to hot, with average temperatures around 25°C at the start of the month and 28°C by the end, and daily highs often near 30°C.[2] That seasonal baseline matters because these markets often stay thin until funding arrives and traders can bridge the on-ramp friction; deposit speed, card fees, and withdrawal options such as Klarna, SEPA or USDC can affect how quickly fresh capital reaches the book.

For catalysts, watch the late-day weather pattern over the city, any heat advisories, and the timing of the final Wunderground update for KLGA, since the market only resolves once the next day’s first reading is posted.[1] In practice, depth tends to improve when payment rails are convenient enough for new entrants to top up quickly, especially on venues where fiat settlement is slower than crypto-native funding and where small delays in deposits can keep a market anchored near zero until the event is nearly resolved.
