Best Travel Seasons

There are varying opinions on the best time to travel. Some sites seems to recommend longer travel seasons I think to push there tours over a longer period. The Travel Talk and Go2Africa seem quite good.

From Travel Talk:

Travelling in Africa in January and February
It is the green season in Southern Africa in January and February. The growing vegetation decreases your chances of spotting animals in the national parks. The rainy season is in full force in East Africa, making it an unpopular time for traveling.

Travelling in Africa between March and May
Since heavy rainfall is common across the region, March and May are not ideal months for safari trips in East Africa. The thick vegetation and high precipitation make wildlife sightings difficult. The weather in South Africa is mild and dry at this time of year. However, it may not be the best time to visit Africa, as wildlife activity is not at its finest in this season.

Travelling in Africa between June and August
The weather is comfortable for safari trips in Zambia, Zimbabwe, and Southern Africa. Yet, it is not the best time for Africa tours as wildlife activities are not at their most vibrant until September.

Travelling in Africa in September and October
September and October are the best months of the spring season in East and Southern Africa. Temperatures are at comfortable levels, and the dry weather makes it the best time for safari trips in the vast wildlife areas of Namibia and Botswana.
Spotting wildlife is easy in the dry season since animals gather around the waterholes. Also, the dry grass makes wildlife sightings easier in the national parks of East Africa in these months.
The west coast is blooming with wildflowers, and East Africa hosts the Great Migration from June to October. It is the best time to visit Africa for whale spotting in the Cape. Bird flocks also start arriving in East Africa in October, creating fascinating views.
Lesotho and the Cape region are also popular destinations at this time of year, as temperatures are pleasant at 30°C and the weather is comfortably dry. Packing up for cold nights is advisable as temperatures drop below zero in the eastern regions.

Travelling in Africa in November and December
Temperatures rise, and occasional rains are seen across Southern Africa beginning in November. It is a perfect time for trips to Africa to experience the best of wildlife sightings as migrations and animal births continue.
The rains are more frequent in Uganda and Rwanda in November. December offers a brief break from the rainy season, making it an ideal time for gorilla tracking in the region.
The Cape region is wonderful at this time of year. With the holidays approaching, leisure activities in iconic cities like Cape Town and Durban offer a joyful time. 

Go2Africa has very detailed seasonal information on a variety of locations: South Africa, Botswana, Namibia, Zimbabwe, Zambia, Mozambique and Victoria Falls.

The best time to visit Tanzania (to see the Serengeti and Ngorongoro Crater):

By Philip Briggs
(Philip is a renowned Africa expert and author of many Bradt guidebooks to African destinations, including the guide to Tanzania.)

The best time to visit Tanzania is during the Dry season, from June to October, when wildlife viewing is generally at its best. This is also the best time to see the wildebeest migration in Serengeti National Park. The most reliable time to see the wildebeest calving is January to February. The Southern and Western circuit parks are best visited during the Dry season (June to October), unlike the more popular Northern circuit parks that can be visited year-round.
