Recent National Weather Service and model guidance for San Francisco on September 13, 2026, centers on a high near 70°F under sunny to mostly clear skies, with westerly winds of 15–25 mph moderating coastal temperatures via marine air advection. This aligns with the historical average high of 70.8°F and follows a sharp cooldown from the early-September heatwave that produced a 94°F reading on the 9th. Light cloud cover and steady onshore flow reduce the chance of exceeding 72°F, while typical September diurnal ranges support a low probability of sub-68°F outcomes. Updated model runs and real-time observations through midday will refine the exact peak, sustaining trader focus on the 68–71°F range as the most likely 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.
