**Forecast models and real-time observations position 37°C as the leading outcome for Jeddah’s daily maximum on September 10, 2026.** Multiple sources, including WeatherBug, PredictWind, and Yr.no, project a high near 37–38°C (99–100°F) under partly cloudy skies with light west-to-southwest winds and minimal precipitation risk. Coastal sea breezes from the Red Sea typically moderate peak heat in Jeddah during September, keeping values close to the month’s climatological average of roughly 37–38°C while humidity remains elevated. Recent station data from the prior week show daily maxima of 36–38.4°C with no extreme heat events or model shifts, supporting the market’s tight clustering around 37°C (62% implied probability) and 38°C (34.5%). A modest chance for 39°C or higher (6.5%) exists if afternoon heating exceeds expectations or winds weaken, but consensus across ECMWF, GFS, and local guidance favors the lower end of that range. Official resolution will rely on verified readings from Jeddah King Abdulaziz International Airport or equivalent Saudi meteorological stations, with any final adjustments driven by the day’s observed peak rather than pre-event models.

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 10 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 and real-time observations position 37°C as the leading outcome for Jeddah’s daily maximum on September 10, 2026.** Multiple sources, including WeatherBug, PredictWind, and Yr.no, project a high near 37–38°C (99–100°F) under partly cloudy skies with light west-to-southwest winds and minimal precipitation risk.
