We run all year but the summer, roughly April through October, is the best window for calm water and consistent access to the coastline. Winter swells from the north settle down during these months, which means fewer weather cancellations, steadier conditions for snorkeling at spots like Nualolo Kai / Makole and better odds of sea cave entry, since caves are only entered as long as ocean conditions allow. Summer is also peak booking season, so tours sell out further in advance than they do in winter.
