Jeddah's peak August heat stems from intense solar radiation near the summer solstice combined with high humidity from the adjacent Red Sea, which limits nocturnal cooling and elevates daily maxima. Long-term climatology shows average highs near 37–38°C, with occasional spikes above 40°C driven by weak steering winds or regional heat advection. Current forecasts through mid-month indicate potential for 39–41°C readings on August 13 amid stable high-pressure patterns, supporting the market's leading 41°C-or-higher outcome at 42% implied probability. Model consensus remains moderate due to typical variability in Red Sea moisture and wind regimes, keeping 39°C and 38°C viable at 19% and 14.5% respectively. Traders weigh official meteorological agency guidance on diurnal ranges and any late adjustments to upper-level ridging that could push or cap extremes.
