Recent National Weather Service and model guidance shows San Francisco cooling into the mid-60s on August 29 under strengthening onshore flow and a deepening eastern Pacific trough, with west winds of 10-20 mph promoting marine-layer influence and partial cloud cover that limits afternoon heating. This follows several days of near- or above-average warmth and precedes further cooldown, placing the most likely highest temperature near the 64-67°F range while allowing for modest variance from exact clearing timing or station-specific readings. Historical August highs average near 69°F, but the current pattern aligns with below-normal conditions favored by the Climate Prediction Center, leaving traders evenly distributed across the central bins as they weigh subtle differences in wind strength, cloud persistence, and boundary-layer moisture that could shift the daily maximum by a few degrees.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the San Francisco International Airport Station in degrees Fahrenheit on 29 Aug '26.
The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=ksfo
This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button.
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). Thus, this is the level of precision that will be used when resolving the market.
