The best time to visit Al Khums is during the spring (late March to May) and autumn (late September to November) months.
During these periods, the weather is pleasantly warm and comfortable, with average temperatures ranging from 20°C to 28°C. This makes it ideal for exploring the historical sites like Leptis Magna without the intense heat of summer or the cooler, sometimes wetter, conditions of winter.
Spring brings blooming wildflowers to the coastal areas, making outdoor excursions particularly enjoyable for those who appreciate natural beauty.
