The weather in Tanzania varies depending on the region and the time of the year. The coastal areas are hot and humid, and it rains a lot, especially during the rainy seasons. The centre plateau is much drier and cooler. It's vital to know these weather patterns while planning your Tanzania Safari so that you can have a good time and be comfortable.
Tanzania experiences two rainy seasons: long rains, or Masika rains, from mid-March to May, and short rains, or Vuli rains, from November to mid-January. June to October is the dry season, when the weather is cooler. This is usually the Best Time To Visit Tanzania, especially for safaris and other outdoor activities.
That being said, every season in Tanzania has its beauty and can offer something unique.
