National Weather Service guidance and ensemble models point to a highest temperature near 68–70°F in San Francisco on September 3, driven by persistent onshore flow and a shallow marine layer that limits daytime heating despite seasonal averages near 70°F. Light drizzle or overcast conditions through midday, tied to a weak frontal remnant, further moderate peak readings while southwesterly winds around 10–15 mph enhance mixing of cooler Pacific air. Trader consensus clusters on 68–71°F bins because model spreads remain narrow, with only modest upside risk if clouds break earlier than expected. Historical analogs from similar early-September patterns show maxima rarely exceeding 72°F under comparable marine influence. Updated NWS and NOAA short-range forecasts tonight will likely refine the exact threshold ahead of market resolution.

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.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.
