Ngorongoro in April
April is the wettest month in most parts of Tanzania, and Ngorongoro is no exception, with the crater rim receiving an average monthly rainfall of 220mm. This has no direct effect on wildlife viewing – on the contrary, wildlife populations within the crater are very high in April – but it does mean that a significant proportion of game drives are likely to be partly rained. Taking other parts of the country into account, April is also the peak of the monsoon season on Zanzibar and the coast, and the worst possible month for Kilimanjaro climbs. On a brighter note, at least for those who’ve no intention of climbing Kilimanjaro or exploring the coast, this weight of negative factors mean that tourist numbers on Tanzania’s northern safari circuit tend to bottom out in April, which makes it an excellent time to experience Ngorongoro and the Serengeti at their least crowded.
