Latest numerical weather prediction models from sources including the Met Office and regional forecasters indicate a maximum temperature for Jeddah on August 2 most likely in the 41–42°C range, aligning with the market's closely matched leading outcomes. Persistent summer high pressure, clear skies, and strong solar insolation over the Red Sea coastal plain drive these values, tempered by typical northwest sea breezes that moderate peaks compared to inland areas. Minor model spreads arise from subtle differences in predicted wind speed and timing of maximum heating, with historical August averages near 38°C providing context for the elevated outlook. Updated runs expected overnight will refine whether conditions edge toward 43°C or settle lower.
