The lowest point is where the Shire Valley approaches its confluence with the Zambezi River, at about 100 ft above sea level. The vast water surface of Lake Malawi also profoundly affects the climate. The temperature generally decreases and the rainfall increases with altitude. Malawi is noted for its rapid transitions from low to high rainfall. The tea belt profits from both winter and summer rains, and the high plateau area offers opportunities for afforestation because of heavy rainfall.
Winters are cool, with occasional spells of cold weather.
A valid passport, with at least six months to expiry date from intended exit date, is required to enter Malawi. If your passport is likely to expire you should get a new one before arriving. Visas are not obtainable at points of entry must be organised prior to travelling through the nearest Malawian Embassy or High Commission.
