Recent forecasts and climatological data point to typical mid-summer conditions over the Red Sea coastal plain, where strong solar heating, minimal cloud cover, and a persistent thermal trough favor daytime maxima near 38–40 °C. Historical August averages for Jeddah reach 38 °C, with recent observations already touching 41 °C, keeping the market’s closely bunched probabilities on 38 °C (20 %), 39 °C (23.5 %), and 40 °C+ (30 %) aligned with the narrow range between normal and modestly above-normal heat. Subtle differences among these outcomes hinge on short-term variables such as Red Sea breeze timing, boundary-layer moisture, and any late-day convective suppression that could trim or boost peak readings by 1–2 °C.
