Al Majma'ah (المجمعة) sits in the north of the Riyadh region and shares the classic hot, arid desert climate of central Saudi Arabia: long, intensely sunny summers, mild winters, and very little rain across the year. Whether you're planning a weekend trip, a family visit, or a move to the area, knowing the seasonal rhythm helps you choose the right time to explore comfortably. This Saudi Living guide breaks down what to expect month by month and when to go.
The Climate in Brief
Al Majma'ah has a dry desert climate with abundant sunshine and low annual rainfall. The average annual temperature sits roughly between 25°C and 30°C, but the gap between summer and winter is wide. Summers are extreme, winters are pleasant, and rain — when it comes — is sparse and unpredictable.
Summer (May–September): Very Hot and Dry
This is the harshest stretch of the year. Daytime highs typically reach 40–45°C and often push past 45°C in the peak of July and August, sometimes touching 44–46°C. Nights stay warm too, frequently above 25–30°C. Recent forecasts for the 2026 season point to the same pattern, with June–August highs around 39–43°C and lows near 25–30°C.
- Almost no rainfall, especially in June and July.
- Outdoor activity is best limited to early morning or after sunset.
- Stay hydrated, wear light clothing, and use sun protection.
Winter (December–February): Mild and Comfortable
Winter is the most pleasant season. Daytime highs generally hover around 20–25°C, ideal for walking and sightseeing, while nights turn cool with lows around 5–10°C. Bring a jacket for the evenings, particularly in the desert where temperatures drop quickly after sunset.
Rainfall Patterns
Rain in Al Majma'ah is light and irregular. What little falls is concentrated mainly in late winter and spring, roughly from February through April. The driest stretch is summer, especially June and July, when significant precipitation is very unlikely. Don't plan your trip around rain — it's an occasional bonus, not a reliable feature.
The Best Time to Visit
For comfortable temperatures and outdoor exploring, December to February is the sweet spot. January, February, and December stand out for pleasant daytime averages around 20–26°C and cooler nights.
- Best overall: December–February for mild, sightseeing-friendly weather.
- Good shoulder months: March and November offer warm but less extreme conditions, with a small chance of rain or wind.
- Driest weather: July–September has the lowest chance of rain, but the heat is intense and can limit daytime activity.
Practical Tips
- Plan major outdoor plans for winter or early morning in warmer months.
- Pack layers for winter nights and sun protection year-round.
- There are no special government platforms or fees tied to weather or visiting seasons — general Saudi services are for visas, residency, and municipal needs, not climate or tourism-season information.
In short, Al Majma'ah rewards visitors who time their trip with the cooler months. Aim for winter to enjoy the outdoors at their best, and treat summer as a season for indoor plans and cautious, well-timed exploration.
