April and May are great times of year to visit Botswana.
Heading towards autumn the daytime temperatures start to come down a little and the skies lose the heavier building of clouds as the rains start to disappear.
Towards the latter part of the month, things start to cool off some more and the night time temperatures drop into the teens.
Temperatures tend to be in the high twenties during the day and drop below twenty degrees at night time.
