Tokyo temperature market FAQ

Which weather station settles the Tokyo temperature markets?

Polymarket and IBKR markets use Tokyo Haneda Airport (RJTT).

How do the Tokyo temperature markets settle?

Polymarket settles on the "Temp" readings of NOAA's weather.gov timeseries for RJTT, in whole °C: the highest reading of the day for daily highs and the lowest for daily lows. Weather Underground's Daily Observations table is used only if NOAA's data for the day is unavailable by 11:59 PM ET the next day. IBKR lists ForecastEx Tokyo temperature contracts, which settle on the Weather Underground Daily Observations table for RJTT: the highest reading of the local calendar day for highs and the lowest for lows. The day is final once Weather Underground publishes the first observation of the next day.

What are the Polymarket tickers for Tokyo temperature?

Polymarket has no tickers. Its daily event is titled "Highest temperature in Tokyo on October 16?" with the slug highest-temperature-in-tokyo-on-october-16-2026, and the daily low event's slug starts with lowest-temperature-in-tokyo.
