Recent forecasts from global and regional models place Jeddah’s September 5 daytime maximum near 36–38°C under mostly clear skies, light northwesterly flow, and typical late-summer subsidence. This aligns with climatological September averages of 36–37°C, yet the market’s elevated probability for 40°C-plus outcomes reflects ensemble spread and the potential for slightly reduced cloud cover or stronger surface heating along the Red Sea coast. High humidity and minimal precipitation further support efficient solar absorption, while small differences in boundary-layer mixing or local wind speed can shift the daily peak by 2–3°C. Upcoming high-resolution model runs and updated observations will refine these thresholds ahead of 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 5 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.Recent forecasts from global and regional models place Jeddah’s September 5 daytime maximum near 36–38°C under mostly clear skies, light northwesterly flow, and typical late-summer subsidence.
