Many first-time visitors worry about the rainy season in Hawaii, assuming nonstop storms will ruin their vacation. Fortunately, that’s rarely the case. Hawaii’s tropical climate means rain showers are often brief, localized, and followed by sunshine. In fact, those passing showers are one reason the islands stay so lush and why rainbows are such a common sight.
If you’re wondering when is the rainy season in Hawaii, whether it’s worth visiting during wetter months, and which islands receive the least rain, this guide will help you plan with confidence.

The rainy season generally runs from November through March, although rainfall patterns vary significantly between islands and even between different sides of the same island.
Unlike tropical destinations with months of continuous rain, Hawaii usually experiences:
- Sunny mornings

It can rain on one beach while another beach just a few miles away enjoys blue skies.
