Marine layer and onshore flow from the Pacific are suppressing daytime heating across coastal Los Angeles on August 13, 2026, with National Weather Service guidance and model consensus showing a high near 78–83 °F amid patchy morning fog and increasing afternoon cloud cover. Recent cooldown after earlier heat has reinforced this pattern, keeping observed temperatures in the mid- to upper-70s at many urban stations through midday. Traders have concentrated probability on the 74–77 °F range because these conditions align with historical August marine-influenced days when sea breezes and low stratus limit peak readings, while the slim odds above 80 °F reflect residual uncertainty in how quickly skies clear. Updated afternoon observations and any late model shifts in boundary-layer moisture will determine final resolution.

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.
