WHEN IS THE BEST TIME TO VISIT?
This is an almost impossible question to answer and I'm tempted to say anytime. As a rule of thumb, you can expect the longest sunny days from October to March, but it can get a bit humid too as heavy showers are common particularly in the afternoon. It's also the cyclone season, so there's a small risk of more dramatic weather. June, July and August are cooler months but temperatures are typically still in the mid 20s C (upper 70s F) but it can feel chilly at night (but never cold). Aitutaki is 3 or 4 degrees C warmer than Rarotonga each month but has similar weather patterns. The further north you go, the hotter it gets. Average sea temperatures around Rarotonga range from 25C, 77F (Jun-Aug) to 28C, 82F (Jan- Feb). All I can suggest is you read the more detailed information below and decide for yourself
