When to go
If you visit cook islands there really isn’t any bad time to go but the best time to go if you aren’t going to do much diving is probably April, may, September and October just because it has more sun and less rain and it is a bit warmer at that time too. But for diving it’s best to go in the dry season which is anytime from April to October.
these are some of the best dive sites in all of cook islands
Aavavora passage
Because of the strong currents at Aavavora passage it is always a very exciting dive and also because of the currents it’s a great place to see white tip reef sharks. From April to the end of august divers might even find a big number of gray reef sharks and schools of eagle rays throughout the year. Well you’re diving there you will regularly find turtles and mora rays.
After a bit you will go across a sand chute then drop off into an abyss.
