Recent National Center for Meteorology outlooks and international model guidance indicate above-normal temperatures across Saudi Arabia this summer, with Jeddah forecast highs for August 18 centering on 38–39 °C under sunny conditions and moderate north-westerly winds. This aligns with the city’s Red Sea coastal climatology—historical August maxima average near 38 °C with high humidity—but occurs amid a persistent Middle East heat anomaly that began in May and is projected to add 1–2 °C regionally. Key resolution variables include the precise daily maximum recorded at official stations, potential urban heat-island effects, and any last-minute model shifts in steering flow or moisture. Traders weigh these stable, data-backed forecasts against the narrow two-day window before market close.
