Official measurements from National Weather Service stations, including KLAX, recorded a daily maximum of 80–81°F on August 19, aligning precisely with mid-August climatological norms of 77–82°F for coastal Los Angeles and reflecting the moderating influence of the afternoon sea breeze and marine layer. This outcome, now carrying 100% implied probability in the market, is supported by real-time observations and model consensus that limited inland heat advection and kept afternoon warming in check. Minor upward revisions remain possible only if post-event quality control adjusts the official high due to station-specific reporting or microclimate variations, though historical precedent shows such changes are rare for this location and threshold.

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.
