Hawaii has warm tropical weather throughout the year, but rainfall changes by season, island and location. Understanding Hawaii's rainy season can help you choose the best island, beach area and travel dates for your vacation.
Hawaii Rainy Season
Hawaii's rainy season generally runs from November through March. During these months, the islands can receive more frequent showers, especially on windward and mountain areas. However, rain in Hawaii is often brief and localized, meaning one side of an island may be sunny while another area is wet.
When Is the Rainy Season in Hawaii?
The wettest period in Hawaii usually occurs during the winter months, from November to March. December, January and February are often among the rainier months, especially on north and east-facing sides of the islands.
Does It Rain All Day in Hawaii?
Most rain showers in Hawaii are short and pass quickly. It is common to see sunshine return soon after a shower, especially near coastal resort areas. Mountain regions and lush valleys may experience longer periods of rain.
Which Hawaiian Islands Get the Most Rain?
Rainfall varies greatly across Hawaii. Kauai and the windward sides of the Big Island and Maui are known for lush, rainy landscapes. Areas such as Hilo, Hana and Kauai's North Shore often receive more rainfall than dry resort regions.
Driest Areas in Hawaii
Many popular resort areas are located on the leeward sides of the islands, where rainfall is lower and sunshine is more common. These areas are often the best choice for travelers who want beach weather.
Is Rainy Season a Bad Time to Visit Hawaii?
No. Rainy season can still be a great time to visit Hawaii. The islands remain warm, ocean temperatures are comfortable and many resort areas still receive plenty of sunshine. Winter is also one of the best times for whale watching and big-wave surf on northern shores.
