Traders price the highest temperature in Jeddah on June 22 near 35–37 °C because mid-June climatology at King Abdulaziz International Airport shows average daily maxima of 36–38 °C under strong subtropical ridging and intense solar heating. Recent forecast guidance from models and agencies such as the National Weather Service equivalents indicates a modest cooling trend, with highs near 33–35 °C expected under moderate northwesterly winds and Red Sea sea breezes that enhance evaporative cooling and limit extreme heat buildup. Differentiation among the tightly bunched 35–37 °C outcomes hinges on small variations in boundary-layer moisture, afternoon wind speeds, and exact ridge strength, all of which can shift peak readings by 1–2 °C. Historical analogs confirm that clear, dry conditions with light winds typically push readings toward the upper end of this range, while stronger on-shore flow favors the lower side. No major synoptic shifts have occurred in the past 48 hours to alter this equilibrium.
