Latest GFS and ECMWF ensemble forecasts project Los Angeles highs clustered between 68-76°F on April 5 under weak high pressure and moderate onshore flow, fueling tight market-implied odds across 72-79°F bins as traders weigh marine layer persistence. The marine stratus clouds typical of coastal Southern California in early April may delay burn-off, capping peak temperatures via reduced insolation and enhanced sea breeze cooling, with model spread reflecting uncertainty in boundary layer mixing and stratus dissipation timing. Historical April averages near 71°F at LAX provide baseline context amid climatological spring variability. New 00Z model runs and NWS updates overnight could sharpen differentiation before resolution via official observations.

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.
