Recent National Weather Service and model guidance for Los Angeles points to persistent onshore flow and a moderating marine layer as the main drivers keeping August 19 highs clustered near 79–82 °F, aligning with the market’s heaviest weighting on the 78–81 °F bins. Ensemble runs from the Global Forecast System and European Centre for Medium-Range Weather Forecasts show limited warming aloft and a strengthening sea breeze that typically caps downtown and airport readings in this range during mid-August climatology. Recent observations from Los Angeles International Airport confirm overnight lows near 68 °F and only modest daytime recovery, reinforcing trader consensus around the 80 °F outcome while leaving slim probability mass above 84 °F absent an unexpected offshore wind shift. Updated model cycles tomorrow morning will provide the final resolution inputs.

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.
