Trader consensus on Polymarket reflects tight uncertainty in San Francisco's March 29 high temperature, with market-implied odds clustered around 70-76°F (19.5-22.5%) due to evolving forecast models from NOAA and the National Weather Service. A strengthening upper-level ridge over the Pacific is driving warm advection into the region, boosting ensemble means from the GFS and ECMWF toward the low-to-mid 70s at SFO, up 2-3°F from yesterday's guidance amid clearing skies and reduced marine layer influence. However, persistent coastal stratus and potential low-level inversion could suppress peaks to 68-71°F, differentiating lower-binned support; historical March averages hover near 62°F, but analogs from similar ridge setups favor warmer outcomes. New model runs expected this evening may sharpen the outlook ahead of resolution.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the San Francisco International Airport Station once information is finalized, 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 to "Yes" until all data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
