Recent National Weather Service forecasts and model consensus indicate overnight lows in the low 70s°F for Los Angeles on September 7, driven by persistent onshore flow, above-average Pacific sea surface temperatures, and limited marine layer influence. These conditions favor minima near or slightly above the 1991–2020 average of 64°F, with ensemble guidance showing modest spread from potential variations in wind direction or cloud cover. The closely matched market-implied odds on extreme cold (59°F or below) versus warm (78°F or higher) outcomes reflect trader focus on forecast uncertainty in advection patterns and the resolution criteria tied to official minimum observations at stations like Los Angeles International Airport. Updated NOAA model runs over the next 48 hours will clarify any shifts ahead of the observation window.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=klax
This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button.
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.
