Although Hawaii is known for its warm, tropical climate and year-round sunshine, the weather in February can be somewhat unpredictable.
In February, the trade winds, which bring cooler, drier air from the east, tend to be less prevalent, allowing for more humid and unstable air to move in from the south and west.
This can lead to increased rainfall and cloud cover, especially on the windward (eastern) sides of the islands. The leeward (western) sides of the islands tend to be drier and sunnier, with less rainfall and more sunny days compared to other months.
Overall, February is a wetter month in Hawaii, with the potential for both wet and dry conditions depending on location. Despite the increased rainfall, the weather in Hawaii in February is generally warm and pleasant, making it a good time to visit for those who don’t mind the possibility of some rain.
