Official forecasts for Jeddah on September 23, 2026, point to a daily minimum near 29–30°C, driven by persistent high pressure, light northwesterly winds, and Red Sea moisture that limits overnight cooling. Multiple model runs and airport observations show overnight lows holding in the upper 20s Celsius amid clear to partly cloudy skies and dew points near 25–27°C, consistent with September climatology where typical minima range 26–29°C. Trader emphasis on the 30°C outcome at 65% implied probability reflects this consensus, while lower probabilities for 27–28°C or 24°C or below account for minor model variability or localized urban effects. No significant weather systems or temperature anomalies are expected before 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.
