The BigIsland of HawaiiWeather
Weather on the Big Island of Hawaii changes as rapidly as the terrain around it. No other island has the same diversity as the Big Island; not even by a long shot!
In some areas, rainfall can be absolutely zero; not a drop falls all year long and the terrain reflects this- it's dry and barren. In other areas, it can be rainy every day of the year (as in Hilo or Puna), creating a lush paradise for visitors who enjoy that type of environment. Knowing bothWhen to Visit the Big Island of HawaiiandWhere to Stay on the Big Islandare also important. We encourage you to stop by those pages for more in-depth information.
For the most part, the Big Island is warm and tropical year-round. Average temperaturesnear the major resort areas (coastline) range from 75-85°F (23°C-29°C) in winter and summer, respectively. At the higher elevations like Volcano and Waimea, temperatures are often much cooler, especially during the night. Hilo can also have lower temperatures depending on how far mauka (inland) you travel. And, of course, the summit of Mauna Kea and flanks of Mauna Loa or Hualalai can be quite chilly, if not downright frigid. Plan for snow if you'll be visiting those areas.

*Climate Notes: Weather and Climate numbers are aggregated from trusted weather sources providing the monthly temperature and precipitation figures for the Big Island's primary airports in Kailua-Kona and Hilo. These climate summaries, specific to the airport location, should therefore not be taken as a "whole-island" forecast. Weather conditions can change dramatically on the Big Island due to the diverse topography, changes in elevation, the trade winds, and other unique island conditions.

Big Island of Hawaii Weather Patterns
If you're looking to avoid rain altogether on your Hawaiian vacation, then the Big Island is a good choice. A large majority of the accommodations are located in areas that receive very little rainfall. Below we've created a list of the driest to wettest locations on the island. The map below that list may also help you visualize which areas are the rainiest and sunniest. Most of the rain that falls on the Big Island do so in the winter months when the tradewinds bring more moisture to the islands. This occurs primarily from late November through early March.
- The Kohala (Gold) Coast is almost always sunny year-round and offers the best chance for dry weather, averaging just 0"-10" (0-25 cm) annually. Most of the accommodations here are higher-end resorts.
- The accommodations in and around the Waikaloa area offer the next best selection for sunny and dry weather at 10"-20" (25-50 cm) a year. Accommodations here are similar to that of the Kohala Coast.
- The accommodations in Kailua-Kona offer fairly consistent and dry weather at 20"-40" (50-102 cm) annually. More rain is likely if you move mauka (inland) and up the flanks of Hualalai. There is an abundance of accommodations here.
- Hawi and Honokaa, on the North Kohala coastline, are wetter at 60"-80" (150-200 cm) a year. Accommodations are also more limited.
- The small inns and B&Bs in Volcano are our next area and average between 60"-120" (150-300 cm) per year depending onthe exact location. Rain is frequent here at night.
- The northern Hamakua Coast is a fairly wet region, averaging80"-160" (200-400 cm) annually. Accommodations in this area are somewhat limited.
- Hilo is the wettest major city in the United States at 120"-160" (300-400 cm) annually, so you can expect lush surroundings and lots of rain, especially at night. Accommodations here are also surprisingly limited, though some small hotels and inns do exist.
