**Trader sentiment for Jeddah’s August 23 minimum temperature centers on 32°C as the leading outcome (66.5% implied probability), followed by 30°C (29%), reflecting consensus from real-time meteorological models and historical summer patterns.** Jeddah’s Red Sea coastal location produces persistently high humidity and limited diurnal cooling, with typical August overnight lows of 28–30°C under stable high-pressure conditions and light northwest winds. Current forecasts from multiple sources indicate a minimum near 30–32°C (roughly 86–90°F), driven by clear to partly cloudy skies, minimal cloud cover, and dew points around 20–24°C that suppress radiative cooling overnight. Recent August 2026 observations show daily minima mostly 29–32°C amid above-normal warmth, with no significant weather systems or Red Sea moisture surges altering the pattern. The narrow implied-probability spread underscores low forecast uncertainty for this resolution window, though final station readings (e.g., from King Abdulaziz International Airport) could shift slightly based on exact timing of the daily minimum, typically occurring pre-dawn.
