Traveller notes on Aitutaki in January
Other months in Aitutaki
Aitutaki's forum calls August comfortable but rarely warm at night — regulars say a long-sleeved top is worth packing for evenings on the beach front. Any rain tends to be a short, 10-minute downpour before it clears again, and while the water is a little coolish for August, most snorkelers manage fine in a t-shirt and shorts.
