Forecast consensus from multiple models places Jeddah's September 18 maximum near 37–38 °C under stable high pressure, clear skies, and light westerly winds typical of the Red Sea coastal regime. Recent observations show daily highs fluctuating between 36–39 °C, with a brief spike to 41.4 °C on the 15th, keeping trader focus tightly on these two outcomes. Differentiation between 37 °C and 38 °C hinges on small model spreads in peak afternoon heating, modulated by humidity (50–60 %) and wind speed variations that alter the surface energy balance. Low precipitation risk and minimal cloud cover reduce downside uncertainty, while the proximity to resolution tomorrow limits further shifts absent an unexpected model revision. Historical September averages near 36 °C provide baseline context for the current elevated readings.

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.
