Winter (December - March)

Highlight: Humpback Whale Season!

During the transit to Molokini, you will almost certainly see whales breaching in the Ma'alaea Bay. **Conditions:** North swells make shore snorkeling difficult, but Molokini stays sheltered. **Visibility:** 80-120 feet.

Spring (April - June)

Highlight: Manta Rays & Turtles

Plankton levels can fluctuate, bringing in larger filter feeders. **Conditions:** Shoulder season offers a great balance of light winds and warm air. **Visibility:** 100-150 feet.

Summer (July - September)

Highlight: Exceptional Visibility

With minimal swells and light trade winds, visibility often hits its peak (150+ feet). Best for underwater photography. **Conditions:** Hot and glassy in the mornings. **Visibility:** 150+ feet.

Fall (October - November)

Highlight: Fewer Crowds

The "slow" season for tourism means fewer boats at the moorings. **Conditions:** Transitions to winter patterns; check forecasts as "Kona winds" can occasionally close the crater. **Visibility:** 100-120 feet.
