Current forecasts from multiple models indicate a September 20 nighttime minimum near 28–29°C under clear skies, light westerly winds, and high humidity near 65–80%, consistent with recent observations showing elevated minima 1–2°C above long-term September averages. The near-even market split between 24°C or below and 34°C or higher reflects uncertainty in exact nocturnal radiative cooling rates, modulated by Red Sea thermal inertia, dew point levels around 25–28°C, and minor variations in boundary-layer mixing. Stable high-pressure dominance and negligible precipitation risk limit cooling potential, while any slight increase in cloud cover or wind could raise the observed low. Updated model runs and official station data in the next 48 hours will refine these thresholds ahead of market resolution.

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=oejn
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 Metric Units" button until the relevant table displays °C.
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 Celsius (eg, 9°C). 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.
