Climate guide to Saudi Arabia
Most of Saudi Arabia has a desert climate, with an intensely hot, dry summer between May and September, and a mild winter between December and March.
Indoor spaces are air-conditioned as standard in Saudi Arabia, including hotels, shops, museums, and vehicles. However, outdoor attractions such as the AlUla archaeological area, the historic district of Al-Turaif, and the Rub' al Khali dunes offer little escape from the sun. As such, the best time to visit Saudi Arabia is during the cooler months of November through to March. This allows you to explore more of the country’s highlights comfortably – though you should always prepare for warm weather and strong sun.
Saudi Arabia has one of the lowest levels of annual rainfall in the world, and much of this is concentrated in the southwest of the country. Most rain falls during winter and spring, helping to quench the desert vegetation before the long, dry summer.
What to wear for Saudi weather
To protect yourself from the desert sun, we recommend wearing sunscreen, sunglasses, loose linen clothes that cover the arms and legs, and a wide-brim hat, cap with neck cover or head scarf.
If you are visiting during the spring, especially in the southwest, you may wish to pack a light raincoat. An additional layer is also advised if you will be outside during the evening, or visiting mountainous regions, as it can get cold.
