The Moremi Reserve is wonderful throughout the year, the extraordinary concentration of wildlife makes it one of the best places for safari across the African continent; but the alternation of the seasons and the flood of the Okavango Delta have an inevitable influence on the visit to this location and the activities that take place there.
The rainy season begins between November and December, but rains are mainly concentrated in the months between January and March; in these months the vegetation is lush and makes the sighting a bit more difficult, and animals are no longer obliged to stay near the Okavango Delta, but can move freely in the area as water sources are available everywhere.
This also means that in the Moremi Reserve, particularly in the Mopane Tongue, there is a kind of migration of herbivores that move North to the Chobe and South to the salty expanse of Makgadikgadi and Nxai and towards the Central Kalahari.
While in the dry season, from April to October, the animals are concentrated in the Okavango Delta and in the Moremi Reserve, with an exceptional density; sightings are spectacular and off-road and boat safaris give indescribable emotions.
The Chief Island is less interested by this phenomenon of migration because, being an island disconnected from the land, animals cannot move to go elsewhere and therefore they are present throughout the year.
From October to April there are also the birds in the Moremi Reserve that migrate here from the Boreal Emisphere, the best months for birdwatching are from September to November, that is, at the end of the dry season when the aquatic species concentrate on the marshes and in the swamps and along the rivers, such as the Khwai River; but throughout the year the Moremi is a paradise for birdwatchers.
From the climatic point of view, the beginning of the dry season, that corresponds to winter, in the months of June to August, presents mild days and cold nights, clear sky and no humidity; while in the months to come, from September to November, the temperature gradually begins to rise and, with it, also the humidity rate.
The storms, that mark the beginning of the rainy season, give dramatic views and bring some coolness accompanied by less humidity; the rains are mainly concentrated in the months of January to March; while from April the temperatures begin to decrease, rains are now a remembrance and the sky is always clear and cloudless.
From May onwards it reaches the Okavango Delta and the Moremi Reserve the flood of the Okavango River, in addition to being the main source of water in this area of Botswana for herbivores, that return here in mass, it is also the best time to carry out safari by mokoro and boat because the canals, the swamps and the marshes are full of water and thus allows to make good excursions.
Off-road safaris can be carried out all year long, the only concern is to choose the area to go according to the time of the year; some fields, during the flood of the Okavango, have a smaller surface where to lead the guests, because they are partly submerged by water; sightings are still superb.
