Best time to visit the Big Island


Balmy and warm all year round, any time of year is a good time to visit the Big Island, Hawaii.

For mainly dry and sunny conditions it’s probably best to visit during summer, from May to November, when the average high daytime temperature is 29°C (84°F).

The rainy season lasts from December to March, when you can expect slightly cooler temperatures and heavy rain in the mountains and short showers elsewhere. Winter has an average high daytime temperature of 27°C (81°F).

Note: Hawaii is full of microclimates, given its many valleys, mountain peaks and coastal plains. The leeward sides (west and south coasts) of each island are usually hot and dry, while the windward sides (east and north coasts) are generally cooler and wet.
