Recent National Weather Service and ensemble forecasts for Los Angeles on September 15 indicate overnight lows near 66–68°F under a strengthening marine layer, with patchy coastal fog and light onshore flow limiting radiational cooling. This setup supports the near-even market split between the 68–69°F bin and outcomes at 61°F or below, as small differences in fog persistence, dew point recovery, or clearing timing can shift the daily minimum by several degrees. Historical September averages near 64°F provide context, but current high pressure and sea surface temperatures favor milder readings unless stronger offshore flow develops overnight. Updated model runs and morning observations will clarify resolution ahead of the close.

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.
