Recent National Weather Service and model guidance point to an overnight low near 68°F for downtown Los Angeles on August 21, shaped by a persistent high-pressure ridge that has suppressed the marine layer and maintained elevated dew points around 60–65°F. This limits radiative cooling after sunset, as higher humidity and light onshore flow reduce the temperature drop compared with drier, clearer nights. Small differences among the closely bunched 66–71°F outcomes hinge on exact marine-layer depth, cloud-cover timing, and wind speed in the final hours before the daily minimum is recorded at the official station. Historical August lows average near 66°F, so any deepening of the cool, moist boundary layer tonight could push readings toward the lower end of that range, while continued subsidence would favor the upper side.

This market will resolve based on the lowest 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 lowest temperature recorded at the Los Angeles International Airport Station in degrees Fahrenheit on 21 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest 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.
