Recent official forecasts for Jeddah on September 30 converge on a daily maximum of 34–37°C under stable subtropical high pressure, light westerly winds, and clear skies that favor strong daytime solar heating over the Red Sea coast. Model consensus from sources including the Met Office, Yr.no, and regional analyses places the peak near 35–36°C during the afternoon hours, consistent with late-September climatology when average highs reach approximately 36°C. The absence of cloud cover, moisture influx, or frontal systems keeps variability low, supporting the market’s heavy weighting toward 35°C and 36°C outcomes. Updated model runs and official briefings expected tomorrow morning represent the final data points before resolution.
