When Is the Best Time to Dive in Hawaii?
Hawaii is a year-round destination, but conditions change with the seasons:
- Summer (May–Oct): Calmer seas, best visibility and ideal conditions for most islands.
- Winter (Nov–Apr): Bigger surf on north shores, with humpback whales migrating through.
- Night dives: Kona mantas run year-round with consistent sightings.
Water temperatures average 24–27°C, so a 3–5 mm wetsuit is comfortable.
How to Plan Your Hawaii Diving Trip
- Pick the right island: Kona for mantas, Maui for Molokini, Lanai for cathedrals.
- Book remote sites early: Niihau and Molokai trips are limited and weather dependent.
- Respect ocean conditions: Winter swells can cancel boat trips, especially on north shores.
- Plan for depth: Some walls and wrecks require AOW or deeper experience.
- Compare dive centers: Use Be Underwater to review operators and plan your itinerary.
