Forecast models from sources like the Met Office, ECMWF, and GFS indicate a likely daily maximum of 36–38°C for Jeddah on September 25 under persistent clear skies and light northwesterly flow off the Red Sea. Stable subtropical high pressure supports strong daytime solar heating with minimal cloud cover or precipitation, while typical late-September sea-surface temperatures near 31°C and moderate humidity moderate the peak slightly through boundary-layer mixing. Recent observations show daily highs fluctuating between 36–38°C, with small differences in wind speed or advection potentially shifting the exact maximum by 1–2°C. This narrow uncertainty range underpins the market's even distribution across 34–39°C outcomes, as traders weigh the latest model consensus against the potential for minor forecast revisions before resolution.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the King Abdulaziz International Airport Station in degrees Celsius on 25 Sep '26.
The resolution source for this market will be information from NOAA, specifically the highest 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.Forecast models from sources like the Met Office, ECMWF, and GFS indicate a likely daily maximum of 36–38°C for Jeddah on September 25 under persistent clear skies and light northwesterly flow off the Red Sea.
