Forecast models from sources including WeatherBug, PredictWind, and Yr.no indicate Jeddah highs near 36–37°C on September 3, consistent with early-September climatology under persistent subtropical high pressure, clear skies, and northwest sea-breeze winds that limit extreme heating while maintaining low humidity. The tight spread among 37°C, 38°C, and 39°C+ outcomes in trader pricing reflects genuine uncertainty in peak diurnal temperature, driven by small differences in model timing of maximum insolation, wind speed, and boundary-layer mixing rather than any synoptic shift. Stable conditions with negligible precipitation risk and no recent model trend toward cooling or intensification keep probabilities clustered in this narrow band, with resolution hinging on final observational data from local stations.

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.
