Trader consensus around 30°C or cooler for Jeddah's lowest temperature on September 21 reflects short-range forecast models showing overnight lows of 28–31°C amid stable high pressure, light winds, and clear skies. Coastal Red Sea humidity and the region's typical 6–8°C diurnal range support these values, with recent observations confirming similar minima near 29°C. Differentiation between sub-26°C and 30–32°C outcomes hinges on precise nocturnal cooling rates influenced by dew point and wind shifts, where even small model revisions could alter the recorded minimum. Official updates from regional agencies over the next 48 hours will likely refine trader positioning 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 21 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.Trader consensus around 30°C or cooler for Jeddah's lowest temperature on September 21 reflects short-range forecast models showing overnight lows of 28–31°C amid stable high pressure, light winds, and clear skies.
