**Official National Weather Service forecasts for San Francisco on August 21, 2026, point to overnight lows in the upper 50s amid a persistent marine layer and moderate westerly winds of 10–20 mph.** These conditions, typical for the Bay Area in mid-August, limit radiative cooling and keep minimum temperatures near the 1991–2020 climatological average of 55.9°F. Recent model consensus and observed trends from the prior evening (lows near 56°F) reinforce expectations for a daily minimum around 56–59°F, aligning with the market’s strong 82% implied probability on the 58–59°F bin. Minor variations in fog clearance timing or wind strength could nudge the exact reading within the upper 50s, but no major atmospheric shifts are indicated through the night.

This market will resolve based on the lowest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the lowest temperature recorded at the San Francisco International Airport Station in degrees Fahrenheit on 21 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest temperature recorded for all times on this day for the San Francisco International Airport Station, available here: https://www.wunderground.com/history/daily/us/ca/san-francisco/KSFO.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
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.
