The safari season in Botswana runs from March through November. From December until the end of February is the rainy season and the wildlife is dispersed throughout the region. April and May are both delightful months to visit Botswana - marked by moderate temperatures, with highs averaging 88 degrees F (31 degrees C), and lows averaging 60 degrees F (15 degrees C). June, July and August are the winter months, marked by cloudless days and mild temperatures. Lows average 45 degrees F (7 degrees C), and highs average 80 degrees (27 degrees C). The landscapes outside the Okavango Delta begin their drying process, gradually fading from lush green to dry khaki colors. In the delta, the flood waters from Angola start to fill the countless lagoons and streams. September and October can be compared to Spring in the Northern Hemisphere - a delightful time of year to visit Botswana. Highs average 90 degrees F (31 degrees C), and lows average 60 degrees F (15 degrees C). The occasional rain shower may be experienced towards the end of October. Game viewing is excellent due to the lack of thick vegetation and the waterholes are drying up. November, early December and March are considered summer months, with highs averaging 98 degrees F (32 degrees C), and lows averaging 65 degrees F (16 degrees C). These months border the rainy season, when you may encounter brief, but heavy rain and thunder storms. November and December still afford the visitor excellent game viewing.

Most people don't go to Botswana between November to March, but there are SOOO many advantages to going off-season. Many of the reasons are listed here: http://www.coreafricanexperiences.com/cheap-travel-tips-in-africa-1/ This the rainy season, this is true, but also calving season (so this is when all the baby creatures are born). It's when the bush really comes alive with young creatures being born and predators on lookout for the vulnerable or unattended. You also avoid the masses of tourists. I'd suggest going between November and March (but bring your galloshes and be ready for a physical adventure!)
