Current ensemble forecasts for Jeddah place the September 13 minimum near 28–30°C, consistent with climatological September lows of 28–29°C and recent station observations. Trader equilibrium between 25°C-or-below and 35°C-or-higher bins, alongside elevated probability at 31°C, reflects model spread in overnight radiative cooling under clear skies, light variable winds, and persistent Red Sea humidity that limits temperature drops. Coastal urban heat-island effects and stable high pressure further constrain variability, while any shift in steering flow or moisture advection could alter the nocturnal minimum before resolution.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the King Abdulaziz International Airport Station in degrees Celsius on 13 Sep '26.
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.Current ensemble forecasts for Jeddah place the September 13 minimum near 28–30°C, consistent with climatological September lows of 28–29°C and recent station observations.
