Bujumbura in November

June through September is your sweet spot. The dry season means less humidity, clearer skies, and better road conditions for exploring. Temperatures hover around 75-80°F during the day, perfect for walking around the city or taking boat trips on the lake. July and August are peak months — you'll get the most sunshine and the calmest lake conditions. The rainy season (October through May) isn't terrible, but afternoon downpours can disrupt plans and some roads become impassable. March and April see the heaviest rains. But here's a plus: the rainy season brings lush green landscapes and fewer visitors, so hotel prices drop. Just pack an umbrella and flexible expectations.
