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 17 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.
Recent National Weather Service forecasts for the Los Angeles area point to a highest temperature of 77–78°F on August 17, driven by persistent marine layer influence and a moderate onshore sea breeze that limits daytime heating. This aligns with the market's strongest consensus around 78–79°F (50.5% implied probability) and the secondary cluster at 76–77°F (25.5%). Coastal stations typically record several degrees cooler than inland valleys under these conditions, while model guidance shows limited warming potential absent a strong offshore flow or high-pressure buildup. Historical mid-August averages near downtown reach the low-to-mid 80s, but current synoptic patterns favor below-normal readings, keeping the 80–81°F outcome at just 15% and higher thresholds under 4%. Updated model runs and morning soundings over the next 24 hours will refine the final observed maximum before market resolution.
