Highest temperature in NYC on July 30?

Platform comparison

Market context

The event is the **highest temperature recorded at LaGuardia Airport on 30 July 2026**, measured in Fahrenheit and resolved from the day’s Wunderground history page. With the market currently at **0% YES**, the crowd is effectively pricing in a very low likelihood that the final reported high lands in the contract’s YES band, which is typically only rational if traders expect a cooler-than-usual day or a range that excludes the observed high.[1][4]

For context, late-July New York City temperatures often sit in the 80s, and recent local weather pages for 30 July show highs around **87–88°F** in Manhattan, with nearby forecasts also clustering in the upper 70s to low 80s earlier in the month.[1][5][9] That makes the market read less like a binary weather shock and more like a question of whether the airport station’s official high clears the relevant threshold by a narrow margin, as airport observations can differ from city-centre forecasts.

From a market-access perspective, German users need to factor in the **GlüStV** framework, which can restrict participation in online gambling-style products even where the event is informational rather than purely recreational; that is a jurisdictional access issue, not a view on merit. In the US, the **CFTC** has reach over derivatives-style activity and operator conduct, so venue structure matters for whether a prediction contract is offered to US persons. For this specific market, “**no-KYC up to $1,500**” usually means a trader can reach that cumulative activity threshold with lighter identity checks, but it does not remove platform controls, sanctions screening, or any regional eligibility limits attached to weather markets.
