Jeddah's August climate, shaped by Red Sea humidity and persistent high-pressure systems, produces typical overnight minimums of 29–31°C according to long-term records and current model guidance from sources like AccuWeather. This climatological baseline underpins the market's overwhelming 93.5% implied probability for a 31°C low on August 21, 2026, as recent daily forecasts show nighttime readings stabilizing near 30°C with minimal day-to-day variability. Lower outcomes below 29°C remain improbable absent an atypical synoptic shift, while the narrow uncertainty range reflects the strong historical consistency of summer minimum temperatures in this coastal desert environment.

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.
