Al Majma'ah, in the northern reaches of the Riyadh region, is a classic inland desert town where the weather shapes almost everything about a visit. With a hot, dry climate and very little rain, choosing the right season makes the difference between comfortable sightseeing and a struggle against the heat. This guide from سعودي ليفنج breaks down what to expect month by month and when to plan your trip.
The climate in brief
Al Majma'ah has a subtropical desert climate, meaning long, intensely hot summers and short, mild winters. The dry air is a defining feature: humidity stays low for most of the year, so the heat feels dry rather than sticky. Key averages include:
- Average yearly temperature of about 29.7 °C
- Average annual high around 34.4 °C
- Average annual low around 21.9 °C
Rainfall: expect very little
Rain is rare here. The town receives only around 9–10 mm of precipitation across the whole year, spread over roughly 22 days with measurable rain. April is usually the wettest month, occasionally bringing short bursts of rain, while midsummer months — especially July — are typically bone dry. Travellers should plan around heat rather than rain almost year-round.
Summer: hot and demanding
From June through August, daytime temperatures often climb to 44 °C or higher, with historical peaks around 45–46 °C. The heat is prolonged through the afternoon, and July through September remain especially hot and dry, with averages in the mid-30s °C or above. If you must visit in summer:
- Stick to early mornings and late evenings for any outdoor activity
- Carry plenty of water and stay hydrated throughout the day
- Use air-conditioned transport and plan indoor breaks around midday
Winter: the most comfortable season
Winter is when Al Majma'ah is at its most pleasant. In January, the coolest month, daytime temperatures hover around 20 °C, dropping to roughly 9–12 °C at night. Nights can feel genuinely cool but generally stay above freezing, so pack a light jacket for evenings. December, January, and February offer daytime temperatures of about 20–26 °C — ideal for walking, sightseeing, and desert outings.
Spring and autumn: good shoulder seasons
October and November provide comfortable travel conditions, with averages in the upper-20s to low-30s °C and still-dry air. Mornings and late afternoons are especially pleasant for outdoor activities. Spring can be enjoyable early on, but from May onward the heat builds quickly, and by late spring midday outings become uncomfortable.
The best time to visit
For outdoor exploration, desert trips, or visiting local parks, the stretch from late autumn to early spring — roughly November through March — is the sweet spot. Milder temperatures and the rare chance of rain make this the most rewarding window.
- Best overall: December, January, February for pleasant days and cool nights
- Also good: October, November, and March for comfortable, dry conditions
- Avoid if possible: May through September, when daytime highs regularly exceed 40–44 °C
Whenever you go, weather can vary from year to year, so check a reliable forecast before setting out and time outdoor plans around the cooler parts of the day.
