Forecast models from sources including ECMWF and GFS indicate a minimum temperature near 28–30°C for Jeddah on September 24, driven by typical late-summer conditions with high humidity from the Red Sea limiting nocturnal radiative cooling and light northerly winds. This consensus supports trader focus on the closely matched 25°C-or-below and 35°C-or-higher outcomes, reflecting uncertainty in exact overnight lows amid stable high pressure and minimal cloud cover. Historical September minima average 27–29°C, providing context for the balanced probabilities. Updated model runs and official observations from Jeddah King Abdulaziz International Airport will refine the resolution as the date approaches.

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.
