Malawi's climate is hot in the low-lying areas in the south of the country and temperate in the northern highlands. The altitude moderates what would otherwise be an equatorial climate. Between November and April, the temperature is warm with equatorial rains and thunderstorms, with the storms reaching their peak severity in late March. After March, the rainfall rapidly diminishes, and from May to September wet mists float from the highlands into the plateaus, with almost no rainfall during these months.
