**Trader consensus has converged on 36°C as the highest temperature in Jeddah on September 21, 2026, reflecting strong alignment across forecast models and real-time observations.** Multiple sources, including WeatherBug, Yr.no, and PredictWind, project a daily maximum near 36–36.7°C (97–98°F) under sunny to partly cloudy conditions typical of late September along the Red Sea coast. High humidity (60–70%) and light southwest winds support efficient daytime heating without significant cooling from sea breezes or cloud cover. Historical September averages for the region hover near this range, with official station data (such as from Jeddah King Abdulaziz International Airport) expected to confirm the peak. Realistic challenges include late-day measurement revisions, localized cloud buildup reducing solar input, or shifts in steering winds that could cap the high at 35°C or push it to 37°C, though current data show low likelihood of deviation.

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 21 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.**Trader consensus has converged on 36°C as the highest temperature in Jeddah on September 21, 2026, reflecting strong alignment across forecast models and real-time observations.** Multiple sources, including WeatherBug, Yr.no, and PredictWind, project a daily maximum near 36–36.7°C (97–98°F) under sunny to partly cloudy conditions typical of late September along the Red Sea coast.
