Persistent marine layer conditions, characteristic of San Francisco's June Gloom pattern, suppressed daytime heating on June 12 and anchored the official high at San Francisco International Airport (KSFO) within the 70-71°F range. National Weather Service model consensus and observed stratus coverage with onshore flow prevented significant warming, aligning with the station's seasonal average of 66-72°F and limiting any offshore flow or high-pressure influence that could erode the inversion layer. Trader consensus at near-100% reflects this data-driven stability, with only minor model divergence possible from rapid boundary-layer changes. A sudden marine layer breakdown or anomalous easterly winds before peak afternoon heating remain the primary scenarios that could have shifted outcomes higher.

This market will resolve to the temperature range that contains the highest temperature recorded at the San Francisco International Airport Station in degrees Fahrenheit on 12 Jun '26.
The resolution source for this market will be information from Wunderground, specifically the highest 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.
