The Okavango Delta will fluctuate with the seasons, and change from year to year depending on the rains and flood waters coming from Angola and along the 800-miles long river. The flood waters usually begin in January and peak in May, making the water levels at their maximum by June or July in the Okavango delta. Many travellers will prefer the drier season (May to October) to visit the delta, as it normally guarantees the best wildlife encounters.
But the wet season (December through March) offers spectacular highlights as well, with amazing colours from the onset of the rains and the flowers / vegetation which springs up to the pleasure of so many mammals giving birth during this time.
The Big Five are in good company with a remarkable number of species:
Water in a desert! The Okavango delta is one of the world’s most amazing mysteries. Ten thousand years ago, the area was covered by Lake Makgadikgadi, which mostly dried up by the early Holocene. The Okavango delta (or Okavango Swamp) is formed where the Okavango River, flows from the rain-rich Angolan highlands, empties onto a swamp in an endorpheic basin in the Kalahari Desert, where most of the water is lost to evaporation and transpiration instead of draining into the sea. Each year approximately 11 cubic kilometres of water irrigate the 15,000 km2 area and some flood-waters drain into Lake Ngami. The world’s largest inland delta gives birth to Africa’s largest and most beautiful oasis of lush water-wilderness. It takes the shape of a hand, with the palm permanently filled with water, and the fingertips seasonally flooded and shaping several islands and a labyrinth of papyrus-lined canals, water-lily lagoons, shady forest glades and rich savanna grasslands – an incredible source of life in a country that is 80% arid.
