Nyika's climate differs sharply from the rest of Malawi. The plateau sits at over 2,000 metres and is much cooler year-round; nights can drop to near freezing in the dry season (May to October), and the days are clear and bright. This is the easiest time to visit — roads are passable, the views are unobstructed, and game viewing on the dry grassland is good.
November to January brings the spring wildflower bloom, including the orchid peak, and the plateau turns from gold to green almost overnight. The trade-off is sticky access roads and frequent afternoon storms. February to April is the wettest period, with the road in often impassable; the park is essentially closed to all but the most determined visitors. Bring warm layers, waterproofs, and sun protection — the high-altitude sun is fierce.
