Current forecast models from agencies like the National Center for Meteorology point to a September 17 minimum in Jeddah near 28–31°C, driven by the Red Sea’s marine influence that limits nocturnal radiative cooling amid high humidity and light onshore winds. Clear skies expected overnight support moderate temperature drops from daytime highs around 35–38°C, while any increase in cloud cover or shifts in sea-land breeze patterns could raise or lower the low by a few degrees. Historical September averages near 27°C provide context, but recent stable high-pressure conditions and minimal precipitation have kept trader-implied odds clustered around 29–34°C outcomes, reflecting uncertainty in exact model consensus on boundary-layer mixing and dew point suppression. Updated runs ahead of the 17th will clarify resolution thresholds.

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.
