Rwanda Weather in February
The weather at this time is relatively similar to January, concluding the short dry season. The start of the month will be drier than the end, making February the start of a great time to track chimpanzees, and gorillas in the same safari.
Dry terrain means that if you are looking to hike elsewhere in the country, canoe, or even climb, without the worry of rain cutting it short, this is a good choice, along with January and December.
With dry terrain, trekking to see the mountain gorillas in February can be excellent, and a somewhat shorter trek (rainier months, treks can be very long and muddy).
