Houston weather markets: station KHOU

Polymarket weather markets for Houston settle on the official reading from KHOU. The settlement day runs midnight to midnight in America/Chicago, and buckets are two degrees Fahrenheit wide.

Settlement source cited in the current market rules (checked 30 September 2026): weather.gov timeseries (KHOU).

Before you trade Houston

Every other city and the station that settles it is listed on the settlement station table.

Check the market rules for the station, because the settlement station is the market's decision and can change. Remember the day boundary is America/Chicago: a market titled for one date can still be open while it is the previous day where you are.
