Daytime and evening temperatures in Bora Bora, as well as throughout French Polynesia, are incredibly stable from month to month. Since Bora Bora is even closer to the equator it tends to be even more consistent than Tahiti and Moorea, which are about 140 miles (230 kilometers) to the southwest.
Most people would describe the climate to be nearly perfect in Bora Bora, at least for a week or two at a time. Every day is quite warm and somewhat humid and every night is almost as warm but a bit less humid, so visitors feel like they cool off a bit at night, especially when outdoors.
