Highest temperature in NYC on July 30?

Platform comparison

Market context

The event here is whether the LaGuardia Airport station records the highest temperature in New York City on 30 July 2026, with settlement tied to the day’s maximum reading in Fahrenheit from Wunderground. In practical terms, the market is about the day’s peak heat at a single observing site, not the average city temperature, so a few degrees can move the outcome across range boundaries.

A 0% crowd-implied probability usually reflects either a stale book, a market that has already become impossible, or near-certainty that the realised value will miss the listed “YES” range. Historical New York summer highs show why traders often anchor to the upper 80s and 90s, with AccuWeather’s July view for New York showing 30 July forecasts around the high 80s Fahrenheit and recent comparable late-July highs in the mid-90s in the archive data. LaGuardia itself has a lower record high than some inland parts of the city, so airport conditions can undercut broader “New York City” expectations.

For catalysts, the main drivers are the official forecast evolution, heat advisories, cloud cover, sea-breeze timing, and whether thunderstorms cap the afternoon maximum before the market’s settlement window closes at 12:00 UTC. National Weather Service climate products and day-of forecast updates are the key public references, while any major warm-up or frontal passage will matter more than late-breaking headlines. On accessibility, German GlüStV rules can materially affect whether the market is available to users in Germany, US CFTC reach is relevant where a product is treated as a derivatives-style event contract, and “no-KYC up to $1,500” generally means small-value participation may be possible without full identity verification, although withdrawal, jurisdictional, and anti-fraud checks can still apply.
