Scuba diving and snorkeling in Maui or anywhere around the world is typically the best between 10 am in the morning and 2 pm in the afternoon. This is due to the sun being higher in the sky. The sun angle being more above the surface of the earth allows more light to penetrate the water. Thus, allowing you to see more of the colorful reefs and fish that lie below the surface of the water.
Time of day to Scuba dive in Lahaina, Kaanapali or the west side of Maui is definitely important. Here’s why. On the west side, or on the south side of the island, we have clouds that have formed at the mountains peaks. The earlier it is in the day, the more the sun is behind them. That being said, there is the mountains that caused the clouds to form so densely. They cast a shadow over the west facing shores. This of course results in a darker dive or snorkeling experience.
