Singapore weather markets: station WSSS

Polymarket weather markets for Singapore settle on the official reading from WSSS. The settlement day runs midnight to midnight in Asia/Singapore, and buckets are one degree Celsius wide.

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

What PollyWetter shows for Singapore

• The official WSSS reading and the running daily extreme so far.
• A calibrated live estimate beside the official figure, never instead of it.
• Implied probability for each bucket from the live order book.
• Our own forecast accuracy for WSSS, so the estimate can be judged.

Before you trade Singapore

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 Asia/Singapore: a market titled for one date can still be open while it is the previous day where you are.
