Wailea
When it comes to tropical islands, weather activity can be highly variable across the island. Even if it's raining, you may still be able to find a little patch of sunshine somewhere. Wailea, on Maui's southwest edge, receives the least rain on the island. Wailea is most well-known for its five beaches. Each beach is isolated by borders of lava rock outcroppings, creating pleasant swimming coves.
