June - Beginning of Dry Season
June marks the beginning of the dry season in Tanzania and the start of the northward migration season. Dry conditions prevail and the occasional afternoon or evening thundershower is a welcome relief. Wildlife viewing can be tremendous in June when the migration is on the move and the great herds pour through the Central and Westerns regions of the Serengeti. Additionally, resident animals become concentrated around the remaining sources of water making many species easy to spot.Early June marks the beginning of the dry season, which lasts from about the end of May to the end of October. By early June, the skies have cleared and all the parks have begun their season of change. The landscape changes dramatically as the parks dry out starting first with the plains and last with the woodlands. The weather will be mostly sunny with only a slight chance of rain.
Temperatures are pleasant with an average high of 81 degrees and an average low of 56 degrees. However, the rim of the Ngorongoro Crater can get quite cold at night and in the early morning. Visitor numbers drop off dramatically at the beginning of March and during April and May the parks are completely empty of tourists. Visitor numbers are still low in the beginning of June but begin to rise to moderately high numbers at the end of June.
