The best time of the year to plan a trip to Angola is between June and October. During this time, the weather is quite mild and sunny while the rains and storms have not yet arrived.
For the most part, Angola has only two seasons: dry and wet. The summer months can get a little washed out.
When planning a trip, keep in mind that Angola is an immense country, geographically speaking, and so the weather can vary from place to place.
