Jeddah’s subtropical coastal climate, moderated by Red Sea humidity and persistent high-pressure patterns, typically produces May daytime highs averaging 37 °C. Current model guidance and recent observations showing consecutive days in the mid-to-upper 30s have reinforced trader consensus that the May 17 maximum will reach or exceed this threshold, reflected in the 58 % market-implied probability for 37 °C or higher. Seasonal warming trends and minimal cloud cover expected tomorrow further support limited cooling potential, while narrower brackets around 36 °C capture the residual uncertainty from small forecast spreads. No significant atmospheric disturbance is indicated that would suppress temperatures below the recent baseline.
