Recent National Weather Service and model guidance points to overnight lows in the mid-to-upper 60s for Los Angeles on September 16, driven by a persistent marine layer and onshore flow under a weak coastal eddy amid gradual regional cooling from an upper-level trough. This setup typically keeps minimum temperatures 2–4°F above the 1991–2020 average low of 63.7°F, with morning readings near 66–68°F before daytime clearing. Trader sentiment splits between the 68–69°F and 57°F-or-below bins because small differences in marine-layer depth, wind direction, or clearing timing can shift the overnight minimum by several degrees, while historical September variability and ensemble spread maintain meaningful uncertainty in the final recorded low.

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.
