**Forecast consensus for San Francisco’s high on August 29, 2026, centers on the mid-60s °F, aligning with market-implied odds clustered around 64–69 °F.** Official National Weather Service guidance and multiple models indicate a high near 64–67 °F under partly to mostly cloudy skies, driven by persistent onshore westerly flow and the marine layer typical of late-summer coastal California. Recent days featured a brief warm-up to around 70–75 °F mid-week before cooler marine air returned, with winds of 10–20 mph expected to limit afternoon heating. The leading 68–69 °F and 66–67 °F bins reflect minor model spread on peak insolation and marine-layer depth; stronger fog or thicker clouds would favor the 64–65 °F range, while clearer conditions could push readings toward the upper 60s. Historical late-August averages for the city hover in the mid-60s, providing a stable baseline absent any strong offshore flow or heat advection. Upcoming model updates from the National Weather Service and rapid-refresh guidance will be the key near-term drivers of any odds shifts.

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.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.**Forecast consensus for San Francisco’s high on August 29, 2026, centers on the mid-60s °F, aligning with market-implied odds clustered around 64–69 °F.** Official National Weather Service guidance and multiple models indicate a high near 64–67 °F under partly to mostly cloudy skies, driven by persistent onshore westerly flow and the marine layer typical of late-summer coastal California.
