Kauai’s seven distinctive micro-climates include desert-like conditions on the west side that feature sand dunes, beach resorts are semi-arid tropical weather, there is a cool mountain forest above Waimea Canyon, pastoral plains on the upper-east side, tropical rainforests in the interior of the island, and swamps around Mt. Wai’ale’ale, which is known as the “wettest place on earth”, receiving annual rainfall of over 450 inches. The North Shore of the island is known for being more tropical and green, while the South Shore has the most sunshine.

On such a small island, how does Kauai have such vast geographical differences?

Tradewinds account for some of weather changes and are one-third of the puzzle. Kauai, like the other Hawaiian Islands, has a wayward and leeward side. The tradewinds generally come from the northeast, carrying moisture-laden clouds that funnel their waters into Mt. Wai’ale’ale. This is Kauai’s most valuable resource for clean water. Kauai’s location is another factor, being the northern-most island of the larger islands in the archipelago. The third distinct factor is the high mountain formations throughout the interior of the island. Kauai’s unique climate and amazing biodiversity make it a haven for outdoor activities.

While the island temperatures are important, the ocean temperatures are equally important. Surface water temperatures are very comfortable, ranging from 74 degrees in the winter months like February, to 84 degrees in the summer months. Late September and October are typically the warmest months in Kauai, making it an ideal time to visit the island.
