Recent National Weather Service guidance and ensemble model runs indicate a persistent marine layer and onshore flow will moderate temperatures across coastal Los Angeles on August 19, favoring daily highs near 78–81°F. This aligns with the market’s leading outcomes, where traders have placed the strongest probability on the 80–81°F bin. A coastal trough and strengthening sea breeze are limiting daytime heating compared with inland areas, while historical August normals at Los Angeles International Airport hover around 77–79°F. Any eastward shift in the marine layer or delayed cloud clearance could push readings into the low 80s, though current consensus keeps stronger heat unlikely.

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 19 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.
