Recent forecasts for Jeddah point to a daily high near 37–38°C on June 19, reflecting the seasonal peak in solar insolation combined with typical Red Sea coastal humidity and light northerly winds that limit cooling. Long-term climatology places average June maxima around 36–37°C, with interannual variability driven by subtle shifts in the subtropical ridge and any influx of warmer air masses. Ensemble model spreads introduce modest uncertainty in exact peak readings, particularly regarding afternoon sea-breeze timing and localized cloud cover, which can shave 1–2°C off surface temperatures. These factors explain why market-implied probabilities cluster tightly around 37°C and 38°C while assigning lower weight to extremes outside that narrow range. Updated short-range guidance expected within 48 hours will further refine the outcome.
