The best time to visit Kirundo is during the dry seasons, which run from June to September and December to February.
These months offer more predictable weather, with less rainfall and plenty of sunshine, making it ideal for outdoor activities and exploring the natural beauty of the region. The roads are also generally in better condition during the dry season, making travel within the province more comfortable.
For travellers interested in birdwatching or exploring the Ruvubu National Park, the dry season is particularly good as animals are more likely to congregate around water sources, making them easier to spot. The clearer skies also enhance the experience of visiting Lake Rweru and its surrounding wetlands.
