Recent National Weather Service and model consensus forecasts point to a marine layer and moderate onshore flow keeping Los Angeles highs in the mid-70s on August 13, driving the 76-77°F bin to 49% implied probability. Persistent coastal stratus and fog, typical for the region in mid-August, suppress daytime heating below the seasonal average of 85°F at downtown and airport stations. Ensemble guidance shows limited warming potential without a stronger offshore pressure gradient, while historical analogs from similar patterns confirm peaks rarely exceed 78°F. Updated NWS briefings and overnight model runs through early August 13 will refine these odds ahead of official high-temperature observations.

This market will resolve based on the highest 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 highest temperature recorded at the Los Angeles International Airport Station in degrees Fahrenheit on 13 Aug '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 Los Angeles International Airport Station, 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 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.
