The best time to go to Al Riyadh, Khartoum, is during the cooler months, generally from October to March.
During this period, the weather is much more pleasant, with daytime temperatures typically ranging from 25°C to 35°C. This makes exploring the city's sights and enjoying outdoor activities far more comfortable than in the hotter months. You'll find it easier to wander through local markets or experience the Nile's banks without the intense heat.
For travellers who prefer a balance of good weather and fewer crowds, November and February are particularly good choices. The temperatures are mild, and you can often find good value on accommodation and flights outside of peak holiday times.
If you're interested in cultural events, timing your visit with local festivals, which often occur in the cooler months, can add an extra dimension to your trip.
