Seasonal forecasts from Saudi Arabia’s National Center for Meteorology highlight warmer-than-normal conditions across the Kingdom through October 2026, with probabilities of 60–80% for temperatures 1–2°C above the long-term August average. Jeddah’s Red Sea coastal setting sustains high humidity that elevates apparent temperatures, while peak summer solar insolation, weak pressure gradients, and limited cloud cover promote rapid daytime heating. Short-range model guidance for August 10 currently clusters maximums near 38–41°C, aligning with the market’s combined 69.5% probability on 40°C or higher. Persistent marine heat influences and the absence of significant synoptic cooling events reinforce this outlook, though any late shift in steering winds or increased moisture could moderate readings.
