Forecast models from the Saudi National Center for Meteorology and international agencies consistently indicate a daytime maximum near 37°C for Jeddah on August 19, aligning with typical late-summer conditions along the Red Sea coastal plain where high humidity and sea breezes moderate extremes. Historical August averages hover around 37°C, with recent observations showing stable patterns without significant deviations from baseline climatology. This strong model consensus and lack of anomalous atmospheric drivers underpin the market's near-certain implied probability for 37°C. A realistic challenge could arise only from unexpected shifts in steering winds or localized measurement differences at the official King Abdulaziz International Airport station, though such changes remain low-probability given current guidance.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the King Abdulaziz International Airport Station in degrees Celsius on 19 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the King Abdulaziz International Airport Station, available here: https://www.wunderground.com/history/daily/sa/jeddah/OEJN.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °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.
