Trader consensus on Polymarket reflects tight uncertainty in National Weather Service forecasts for Los Angeles' highest temperature on March 29, with models like the GFS and ECMWF ensembles centering implied probabilities around 74-77°F at 23% and 22.5%, respectively. This positioning stems from a developing high-pressure ridge over the Southwest, forecast to weaken the marine layer and onshore flow that typically caps spring highs near 70°F historically, potentially allowing adiabatic warming aloft. Yesterday's 00Z model runs nudged odds higher from prior cooler biases (70-73°F clusters), but divergent spread in 72-hour outlooks—due to timing of ridge axis and potential low-cloud intrusion—keeps outcomes closely matched. Next 12Z updates from NOAA could sharpen differentiation 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 Los Angeles International Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/us/ca/los-angeles/KLAX.
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.
