Low so far set at 9:56 AM. Same station and day as the high; closes in 5 h 37 min.
From KSFO's NWS climate reports (via the Iowa Environmental Mesonet) and Kalshi's settlements and stored prices. Facts about past days, not forecasts.
Highest hourly reading so far at San Francisco International Airport (KSFO): 65°F at 2:56 PM.
Polymarket's highest-priced range is 64°–65° at >99¢.
Same station as Kalshi, but Polymarket settles on the highest hourly reading, midnight to midnight local time.
Pick a number and Almanac tells you the moment the station (KSFO) reaches it: by email, and on your phone once you switch notifications on. Plus live prices in all 24 cities (these are 30minutes late), 12 weather models' forecasts for this station on the chart and in a table, whether today is running hotter or cooler than they expected, and how each model has done here.
Model record: in our test the market's prices were more accurate than the model (log loss 1.26 vs 1.48 a day ahead, 0.92 vs 1.25 on the day; lower is better).
Every report from the station today (a ), in exact whole °F. “6 h max” is the station's own highest reading over the past 6 hours, which can catch a peak between hourly reports.
