The climate is semiarid in the south and along the coast to Luanda. The north has a cool dry season (May to October) and a hot rainy season (November to April). Natural hazards are locally heavy rainfall, which causes periodic flooding.
In Luanda during the January to April hot season, the temperature is often in the upper 90s; the sun is quite intense; and the humidity is very high. During the winter months, June through September, the days are pleasant, with high temperatures around 80°F, with mild evenings. Skies are often hazy, a condition called "cacimbo." Generally, there are light rains during November and December, with heavy rains falling in March and April.
