National Center for Meteorology forecasts above-normal temperatures across Saudi Arabia through October 2026, with up to 2°C anomalies likely in the Makkah region including Jeddah due to persistent summer circulation patterns. August marks the seasonal peak for coastal Red Sea stations, where high humidity and weak onshore winds limit nocturnal cooling and support daytime maxima. Recent model runs and climatological analogs align with trader consensus favoring 39°C or higher on August 8, reflecting the 55–80% probability of above-average readings issued in late July. Short-term guidance shows modest variability from steering flow and possible marine layer effects, though sustained heat supports elevated odds for the upper bins while leaving room for downward revisions if a brief coastal breeze strengthens.
