Traders have converged on an 80-81°F daily maximum for Los Angeles on August 18 because official observations from the designated reporting station, most likely Los Angeles International Airport, recorded a peak temperature in that narrow band. Coastal marine-layer stratus and persistent onshore flow from the eastern Pacific suppressed daytime heating, keeping surface temperatures near seasonal normals despite warmer conditions farther inland. Recent National Weather Service analyses and model consensus showed no strong offshore wind events or upper-level ridging capable of driving significant warming on that date. While data revisions or use of an alternate downtown station could theoretically shift the final reading, such changes are rare once preliminary maxima are verified and published.

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 18 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.
