Station-truth weather alerts for Polymarket temperature markets
The moment a weather station's running maximum crosses a temperature-bin boundary, that bin's outcome is decided. We watch the stations and tell you the second it happens.
How it works
Polymarket daily temperature markets resolve on official station readings. The running max only goes up — so once it crosses a bin edge, the outcome is locked. We poll official 1-minute and 10-minute station feeds where available, and airport observations elsewhere, and alert on every locked or threatened transition.
Honest framing: liquid markets reprice within minutes of a crossing. This is a convenience data feed that saves you from watching raw station feeds all day — not a promise of profitable trades.
Real examples from July 2026
