**Short-term forecast models indicate a likely daily minimum temperature in Jeddah on September 25 near 28–31°C, producing closely balanced market-implied odds between the 25°C-or-below and 35°C-or-higher brackets amid typical model spread for nighttime lows.** Persistent northerly to northwesterly flow over the Red Sea keeps conditions dry and stable, with clear skies and light winds limiting radiative cooling while high humidity (around 65–75%) and sea-surface temperatures near 31–32°C moderate overnight drops. September climatology shows average lows of 27–29°C at Jeddah, rarely dipping below 26°C or exceeding 32°C under similar synoptic patterns, so current guidance aligns with historical baselines without major anomalies. Differentiating factors for the tight 50%/49% split include minor uncertainties in exact wind speed, dew-point depression, or localized urban heat effects that could nudge the minimum a degree or two in either direction. Traders weigh the latest ECMWF and GFS runs against these variables ahead of final verification data from official stations.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the King Abdulaziz International Airport Station in degrees Celsius on 25 Sep '26.
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.**Short-term forecast models indicate a likely daily minimum temperature in Jeddah on September 25 near 28–31°C, producing closely balanced market-implied odds between the 25°C-or-below and 35°C-or-higher brackets amid typical model spread for nighttime lows.**
