Current forecasts from regional meteorological models project typical early-September conditions for Jeddah, with nighttime lows near 29–31°C driven by persistent Red Sea humidity, light northwesterly winds, and minimal cloud cover that limits radiative cooling. Historical climatology places average September minima around 27–29°C, with rare drops below 25°C requiring unusual synoptic patterns such as stronger onshore flow or transient upper-level cooling not evident in current runs. Trader consensus reflected in the 49.5% implied probability for 24°C or below may incorporate uncertainty around station-specific measurements or potential model underestimation of localized effects, while the cluster of probabilities near 25–31°C aligns more closely with ensemble guidance and recent observational baselines. Updated model runs and Saudi National Center for Meteorology briefings over the next 48 hours will likely refine these odds ahead of resolution.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
