Typically the hottest month with extreme temperatures across inland areas; coastal regions can also be very hot and humid. Travel is possible but outdoor exposure is challenging - indoor, air-conditioned activities dominate.

Average temperature across Saudi Arabia in July.
Jeddah, Yanbu, Al Lith, coastal Tabuk
July is the peak of coastal humidity: mornings are sweaty and nights provide little relief, even with sea breezes. Swimming is the main activity but be mindful of jellyfish season and poorer air circulation in older parts of Jeddah; the corniche is busiest at night. If you’re heat-sensitive, schedule airport transfers and indoor museum visits in air-conditioned windows.
Taif, Abha, Al-Bahah, Jabal Sawda
July and August are the months when the highlands are most comfortable compared with the lowland heat; frequent cloud and orographic rain keep temperatures cool and make hiking rewarding. Abha and Jabal Sawda develop persistent low cloud that can produce mist and drizzle, creating lush roadside vegetation. These months draw local tourism - book accommodation early for popular highland viewpoints.
Riyadh, Buraydah, Al Kharj
July and August are the plateau’s hottest months, with daytime temperatures frequently above 40°C in exposed locations; nights provide only modest relief. Outdoor desert experiences require careful planning: dawn camel treks or evening stargazing are sensible, midday desert drives are uncomfortable and sometimes dangerous. Expect reduced international tourism but steady local travel for holiday weekends.
Dammam, Khobar, Al-Ahsa, Jubail
September brings a small relief as temperatures dip slightly but humidity lingers; the sea remains warm and storms from the Arabian Gulf can appear. Al-Ahsa’s palms tolerate the heat well, and evening promenades along Khobar are more pleasant than daytime. Keep an eye on marine and flight notices during this shoulder season for weather-related disruptions.
Jazan, Najran, parts of Asir lowlands
September is transitional - rain and cloud cover taper off but the landscape remains green and pleasant for a while. Jazan’s islands are warm for swimming and diving, though occasional residual thunderstorms can still appear. Travel is easier as storms lessen; bring rain protection for any mountain excursions and be prepared for sticky, humid pockets on the coast.
Empty Quarter, Al-Ahsa periphery, Salalah-adjacent influences
September’s heat slowly eases but daytime temperatures remain very warm; nights begin to offer more relief and travel windows widen. Dust deposition after the summer can coat vehicles and gear, and occasional storms off the Arabian Sea might produce distant thunder and rare localized flooding near wadis. Continue to prioritize early starts and late finishes.
There are no major festivals or events in Saudi Arabia during July to be aware of.
