Visiting Saudi Arabia in September

23 March 2026 · 1 min read Practical

September is the tail end of Saudi Arabia’s summer season. Temperatures remain high across most of the country — Riyadh averages 37–40°C — but the trend is downward. By late September, evenings and mornings are noticeably more comfortable than August.

Weather in September

Riyadh: Starts at 40°C, drops to around 35°C by late September. Still hot for midday outdoor activity, but more manageable.

Jeddah: 36–38°C with gradually decreasing humidity. The Red Sea coast is warm and accessible for water activities.

AlUla: 38–42°C early month, dropping to 35°C late September. Still warm for Hegra visits.

Abha: 27–30°C. Pleasant throughout September. The mountain cloud and occasional rain begin to decrease by late September as the monsoon influence fades.

Dammam/Al Khobar: 38–40°C with Gulf humidity decreasing as the month progresses.

Saudi National Day (23 September)

Saudi National Day is a significant public holiday. Expect fireworks displays in major cities, public events, and a celebratory atmosphere. The day commemorates the unification of Saudi Arabia under Abdulaziz ibn Saud in 1932. If you are in Riyadh or Jeddah on 23 September, the evening celebrations are worth experiencing. Hotels and domestic flights around this date book up early.

Planning Notes

September is a reasonable month for indoor cultural tourism and for Abha. For outdoor heritage tourism at AlUla and Edge of the World, early October is significantly more comfortable. Prices for hotels and tours are lower than the October–February peak, and crowds are minimal at major sites. If you want AlUla without the peak season rush, late September or early October is the sweet spot.
