**Trader sentiment for the highest temperature in Jeddah on August 31 centers on 38–39°C as the most probable range, with 39°C holding the largest share (40%) of market-implied probability.** This reflects model consensus from sources including WeatherBug, Weather Atlas, and Meteoprog, which point to daytime highs near 38–39°C (roughly 100–102°F) under mostly sunny skies and northwest winds of 5–8 m/s. Jeddah’s arid coastal climate (BWh Köppen classification) drives these outcomes: intense late-August solar insolation over the Red Sea produces typical highs of 36–38°C, moderated slightly by marine air but amplified by high humidity (often 40–60%). Recent observations on August 30 showed afternoon readings of 37–39°C with similar conditions, and no major synoptic shifts—such as altered steering patterns or anomalous warming—are evident in short-range forecasts. Low precipitation probability (near 0%) and stable pressure around 1005 hPa further support persistence of these values rather than extremes. **The distribution favors 39°C as the mode because several ensemble runs cluster there, while 40°C (22.5%) captures upside potential from localized heating and 38°C (25.5%) accounts for modest cooling from stronger winds.** Lower outcomes below 37°C carry minimal weight, consistent with climatological baselines and current model agreement. As resolution nears, traders will monitor any final model updates from agencies like the ECMWF or GFS for refinements to the daily maximum.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the King Abdulaziz International Airport Station in degrees Celsius on 31 Aug '26.
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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.**Trader sentiment for the highest temperature in Jeddah on August 31 centers on 38–39°C as the most probable range, with 39°C holding the largest share (40%) of market-implied probability.** This reflects model consensus from sources including WeatherBug, Weather Atlas, and Meteoprog, which point to daytime highs near 38–39°C (roughly 100–102°F) under mostly sunny skies and northwest winds of 5–8 m/s.
