The coastal strip is tropical with high humidity; temperatures range from 80°F–95°F. The country’s annual rainfall averages 65 inches. The central plateau (altitude 3,000–4,000 feet; rainfall 2–30 inches), which covers much of the country, is hot and dry. The semi-temperate highlands (up to 6,000 feet; rainfall 40–100 inches) are fertile and cool. The islands of Zanzibar (rainfall 60-75 inches), 25 miles off the coast, are tropical and humid.
Tanzania has two rainy and two dry seasons. During the long rains, from March through May, heavy downpours can occur daily (though it is not unusual to have as many as 2-3 days of sunny, pleasant weather between showers). The short rains come in November and December. Temperatures and humidity are high from November to April, and surface winds are moderate. June through September is pleasant and generally mild.
Another weather phenomenon are the monsoon winds, or tradewinds, which blow in different directions during the year. From April to November, the winds can be quite cool.
