Recent forecasts from sources including AccuWeather and timeanddate indicate Jeddah's August 21 minimum will likely reach 31°C, driven by the city's typical summer coastal climate where Red Sea warmth and high humidity suppress overnight cooling, producing average lows near 30°C amid daytime highs of 37–38°C. Persistent subtropical high pressure and light winds have maintained this pattern through mid-August, with early-month observations showing minima of 28.6–31.4°C and no incoming cooler air masses or significant cloud cover to alter trajectories. Trader consensus at 93.5% implied probability for 31°C reflects this stable regime and the low likelihood of deviation within measurement thresholds. Unlikely challengers include sudden wind shifts or localized marine layer changes that could dip readings toward 29°C, though model consensus shows minimal variance through the 24-hour window.

This market will resolve based on the lowest 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 lowest temperature recorded at the King Abdulaziz International Airport Station in degrees Celsius on 21 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest 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.
