Current forecasts from the National Weather Service and other models indicate overnight lows in San Francisco on September 19 will likely settle in the upper 50s, aligning with the market's leading 58-59°F bin. Persistent onshore westerly flow and a moderate marine layer limit radiational cooling under partly cloudy skies, keeping minimum temperatures above the long-term September average of 55.8°F. Recent September 2026 observations show similar upper-50s to low-60s lows amid dry, stable conditions without strong high-pressure ridging that could drive cooler readings. Model consensus supports minimal day-to-day variability through the weekend, though minor shifts in wind speed or cloud cover could nudge the actual low toward the 56-57°F or 60-61°F outcomes.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
