San Francisco temperature market FAQ

Which weather station settles the San Francisco temperature markets?
Kalshi, Robinhood, Polymarket, Polymarket US and IBKR markets use San Francisco International (KSFO).
How do the San Francisco temperature markets settle?
Kalshi settles San Francisco high and low markets on the official high or low for KSFO's NWS climate location, as reported by The Weather Company (then the National Weather Service). Polymarket settles on the hourly data ("Show Hourly Data") of NOAA's weather.gov timeseries for KSFO, in whole °F: 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. Robinhood and IBKR list ForecastEx San Francisco temperature contracts, which settle on the Weather Underground Daily Observations table for KSFO: 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. Robinhood's hourly HRUSFO contracts settle each hour, Central Time, on the last KSFO observation taken after the hour minus 60 minutes and up to the hour, as Weather Underground shows it. Polymarket US settles San Francisco daily high markets on the NWS Daily Climate Report (CLI) for KSFO.
What are the Kalshi, Robinhood and Polymarket tickers for San Francisco temperature?
Kalshi lists the San Francisco daily high under series KXHIGHTSFO and the daily low under KXLOWTSFO. Each day is its own event, such as KXHIGHTSFO-26OCT16 for October 16, 2026, with one market per strike. On Robinhood and IBKR, the ForecastEx San Francisco daily high is UHSFO and the daily low ULSFO. Each contract is one strike on one day: UHSFO_101626_80 asks whether the high exceeds 80 °F on October 16, 2026, and ULSFO contracts ask whether the low is below a strike. Robinhood's hourly San Francisco product is HRUSFO. Polymarket has no tickers. Its daily event is titled "Highest temperature in San Francisco on October 16?" with the slug highest-temperature-in-san-francisco-on-october-16-2026, and the daily low event's slug starts with lowest-temperature-in-san-francisco.
What are UHSFO and ULSFO?
They are the ForecastEx daily high and low temperature products for San Francisco, listed on Robinhood and IBKR. ForecastEx, not Kalshi, is the exchange. UHSFO contracts ask whether the day's highest temperature at San Francisco International (KSFO) will exceed a strike, and ULSFO contracts whether the lowest will be below one, with strikes 1 °F apart. Both settle on Weather Underground's Daily Observations table for KSFO for the local calendar day. Kalshi's San Francisco markets read the same station but settle on the official high or low for its NWS climate location as reported by The Weather Company, not on Weather Underground.
Can I trade San Francisco temperature markets on Coinbase?
Yes. Coinbase lists Kalshi's San Francisco temperature markets (KXHIGHTSFO, KXLOWTSFO) under the same tickers: the markets are operated by Kalshi, share Kalshi's order book and settle by Kalshi's rules, on the same station. Coinbase's prediction markets are not available to Nevada or Michigan residents.
How often does minuteTemp update San Francisco?
KSFO updates temperature every minute, wind and humidity every 5 minutes. Paid plans refresh the dashboard every 60 seconds; the free plan is delayed 3 minutes.
