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. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
Persistent marine layer conditions reinforced by onshore flow and widespread low clouds have suppressed daytime heating across coastal Los Angeles, keeping the National Weather Service forecast for a high near 73°F at KLAX as the dominant driver of the 91.5% market-implied probability on 76-77°F. This setup deviates sharply from August climatological norms near 84°F, with model consensus and real-time observations of patchy fog and limited solar insolation confirming the cooler trajectory. Traders’ strong consensus reflects the low likelihood of rapid layer erosion before peak afternoon temperatures, though a sudden shift in steering winds or reduced cloud cover could allow brief warming into the upper 70s. Upcoming NWS updates and afternoon observations will provide the final resolution data.
