Visiting Saudi Arabia in September

September is the tail end of Saudi Arabia’s summer season. Temperatures remain high across most of the country but the trend is decisively downward — Riyadh drops from 40°C in early September to around 35°C by month’s end, and late September evenings in the capital are noticeably more tolerable than anything in July or August. The key fact: Saudi National Day falls on 23 September and is one of the most atmospheric times to be in Riyadh — fireworks, public celebrations, and a visible national pride across the city.

Weather by City

City	Avg High (°C)	Avg Low (°C)	Conditions
Riyadh	37	24	Falling fast; late September mornings are manageable
Jeddah	37	26	Gradually decreasing humidity; Red Sea accessible all month
AlUla	39	24	Still hot; heritage visits limited to dawn and early morning
Abha	28	17	Pleasant throughout; mountain monsoon influence fading
Dammam	38	27	Gulf humidity dropping; improving through the month

What’s On

Saudi National Day (23 September) is a public holiday commemorating the unification of Saudi Arabia under King Abdulaziz ibn Saud in 1932, when the Kingdom was formally proclaimed. Celebrations take place in all major cities — fireworks displays in Riyadh, Jeddah, and Dammam are large-scale events. Riyadh Boulevard and the Corniche in Jeddah are the focal points for public gatherings. The evening of 23 September is worth being in the country for if your trip overlaps — the atmosphere of national celebration is genuine and unlike any other night of the year. Hotels and domestic flights around National Day book up significantly: plan transport two to three weeks ahead.

AlUla heritage season begins its reopening in late September: guided Hegra tours resume at full capacity from approximately the last week of September, and the Winter at Tantora festival preparations begin. Late September visits to AlUla offer the heritage experience at lower prices and lower crowds than October–November, at the cost of still-warm temperatures.

Shoulder season prices: September is one of the cheapest months to visit Saudi Arabia’s heritage sites. AlUla, Diriyah, and Tabuk hotels are all operating at lower occupancy than peak season, and tour prices may reflect this. For budget-focused travellers willing to manage the remaining heat, September offers good value.

Where to Go This Month

Riyadh around National Day (23 September) is the strongest September recommendation — the city celebration is worth experiencing, and by late September the evenings are comfortable enough for Diriyah’s outdoor pathways and the waterfront areas. Stay at the Four Seasons Hotel Riyadh in Kingdom Centre for central access. Eat at Takya in Diriyah — the heritage dining experience is best appreciated in the evening when the At-Turaif illuminations are running.

AlUla (late September only, early morning schedule): the last week of September is the sweet spot for visiting AlUla outside of peak season — Hegra tours are operating, prices are lower, and the 35°C days are manageable with a strict early-morning schedule. Stay at Shaden Resort — the most affordable of AlUla’s quality properties, with direct access to the valley floor. Dawn visits to the Hegra site require a pre-booked guided tour; book through our AlUla tours page.

Abha remains comfortable throughout September at 28°C — a reliable alternative if the lowland heat is a deterrent. The Abha Summer Festival has concluded, so September is quieter than July and August, with better accommodation availability. Stay at the InterContinental Abha for mountain views and the best restaurant option in the city.

Jeddah is workable in September for early morning Red Sea activities and evening Corniche time. Humidity is dropping from August’s peak. Stay at the Mövenpick Hotel Jeddah for a well-positioned central option. Dine at Dang in Al-Hamra for reliable Thai food in an air-conditioned setting.

Practical Tips for September

• National Day flights: domestic flights on and around 23 September fill early — book 2–3 weeks ahead if your trip includes a Riyadh stay around this date
• AlUla late September window: check with the heritage site directly (via royal.commission.alula.gov.sa) that Hegra tours are fully operational before the last week of September — the heritage season reopening timing can shift slightly by year
• Heat vs. October timing: late September in AlUla is approximately 35°C versus late October at 28°C — if outdoor time is a priority, a one-month delay to late October makes a meaningful difference in comfort
• Hotel pricing: September is one of the best months for hotel value across the country — rates at AlUla, Diriyah, and Tabuk properties are often 30–50% lower than November–February peak rates
• See the Saudi Arabia 1-week itinerary for a route that works in September’s conditions

What to Pack

• Lightweight breathable clothing for daytime (still hot across most cities)
• Sunscreen SPF 50+ (UV remains intense through September)
• Wide-brimmed hat and UV sunglasses for any outdoor activity
• A light jacket for Abha evenings (17°C after dark)
• Reusable water bottle (at least 1.5 litres for outdoor days)
• Modest clothing for all heritage sites and public areas
