**Trader sentiment for the lowest temperature in Jeddah on September 7 centers on 31°C as the leading outcome at 83.5% implied probability, driven by real-time observations and forecast consensus showing overnight lows stabilizing near 30–31°C.** Coastal Red Sea moderation limits radiative cooling under persistent subtropical high pressure, with light northwest winds and partly cloudy skies maintaining humidity levels that suppress sharp temperature drops. Official station data from King Abdulaziz International Airport and numerical models indicate a typical September diurnal range, with daytime peaks around 35–37°C giving way to minimums rarely falling below 28–30°C absent unusual synoptic shifts. Historical climatology places average September lows near 28–29°C, and current conditions align closely without evidence of enhanced cooling from cloud cover or moisture intrusions. Upcoming hourly updates from agencies like the Saudi National Meteorological Center will refine resolution criteria around the precise daily minimum.

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.
