Above-normal seasonal temperatures across western Saudi Arabia, reinforced by National Center for Meteorology outlooks, position 32°C as the leading outcome for Jeddah’s August 23 low at 57.5% implied probability. Persistent high humidity, light Red Sea breezes, and limited nocturnal cooling keep overnight minima clustered near 29–32°C, consistent with historical August patterns where lows rarely fall below 27°C. Recent model consensus favors the upper end of that range amid broader summer warmth projected 1–1.6°C above average. Traders appear to weigh the low likelihood of atypical cooling against ongoing heatwave conditions, with lower outcomes like 28°C or below carrying minimal market weight. Updated forecast runs and any late-day observational shifts from local monitoring stations remain the key near-term variables.
