Forecast models from sources including the Saudi meteorological network and global ensembles indicate a peak temperature near 37–38°C for Jeddah on September 9, driven by persistent high pressure, clear to partly cloudy skies, and light westerly winds limiting cooling from the Red Sea. Recent observations show daily maxima of 36–38°C amid typical late-summer conditions with dew points around 22–24°C and minimal precipitation. These factors position 38°C as the modal outcome in trader consensus while the 24.5% probability on 39°C or higher reflects residual uncertainty in afternoon mixing and any late-model adjustments. Official station readings the following day will resolve the market against these baselines.

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.
