The summer period is characterized by consistently high heat, peaking in June, when the average temperature is 33.2°C, and daytime highs regularly exceed the 36°C mark.

Already in April, the average temperature crosses the 30°C threshold, and September is practically on par with the summer months in its indicators, holding average values around 33°C. Only by November does the heat begin to gradually subside. Thanks to such a climate, it is never cold in Jazan, and travellers can count on warm weather regardless of the month chosen for the trip.
