Meteorological model consensus from agencies including the Saudi National Center for Meteorology and global ensembles like ECMWF and GFS currently positions 37°C as the most probable daily high for Jeddah on September 17, reflecting typical late-summer Red Sea coastal conditions with moderate humidity and limited cloud cover. Recent observations show stable subtropical high pressure and sea surface temperatures near seasonal norms of 30–32°C, supporting modest afternoon warming without significant heat advection or dust events that could push readings higher. Traders appear to weigh the narrow spread between 36°C and 38°C outcomes against forecast uncertainty in boundary-layer mixing and local urban heat effects. Updated model runs and official verification data from Jeddah’s King Abdulaziz International Airport station are expected to resolve the market as temperatures are recorded tomorrow.

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