Looking to holiday in Rarotonga for 7 nights next year, mini mid winter / pre winter break and can't figure out which is the best time to go. May and October are months that come up regularly as good times to visit. We don't mind heat, but would prefer a time when there is less rain, wind and the water is warm and clear for snorkelling. Does anyone know which is better? We are looking at staying at Sanctuary Rarotonga, Aroa Beach, unless someone has a better suggestion.
