Home / Settlement stations

Every Polymarket weather market and the station that settles it

Every Polymarket daily temperature market resolves on the official reading from one named weather station, not on a city average and not on a forecast. This table lists that station for all 51 cities currently traded, with the timezone the settlement day runs in and how wide one bucket is.

The market rules are the authority. A settlement station is the market's decision and can change. Check the rules on the market itself before trading it.

Why the station matters more than the city

Two reporting stations in the same city can differ by more than a full bucket on the same afternoon. Trading "the weather in London" rather than the reading at the named station is the most expensive mistake available in these markets.

Why the timezone matters

The settlement day runs midnight to midnight in the station's own timezone. A market titled for one date can still be open while it is the previous day where you are.
