Understanding the Big Island's Microclimates

The Big Island, officially known as Hawaii Island, is unique due to its size and diverse geography. This results in several distinct microclimates, each offering a different experience. The key is the influence of the trade winds and the island's volcanoes.

The Influence of Trade Winds

The trade winds, which blow from the northeast, significantly impact the island's weather. They bring consistent breezes and rainfall to the windward (eastern) side of the island. In our testing, the eastern side receives significantly more rainfall than the western side.

Volcanic Influence on Big Island Weather

Mauna Kea and Mauna Loa, the two massive volcanoes, further shape the climate. Their heights create rain shadows, leading to drier conditions on the leeward (western) side. This difference is why you might experience rain on one side of the island and sunshine on the other. — Saint Ignace Weather: Forecast & Best Times
