Hawaii Rainfall

The official Hawaiian rainy season is in the winter months, from November to March. As such, the months of April – October tend to have less rain. Though there’s an official rainy season, the fact is it generally rains every day somewhere on every island regardless of the time of year.

However, it is generally more like a light sprinkle than a downpour; rarely lasts more than a few minutes before the glorious sunshine breaks through again. Rainy season or not, it is very rare for it to rain continuously for days.

Additionally, most of the rain that falls in Hawaii occurs overnight. As such, in most cases, rain won’t affect your day.

 

Best Time To Visit Hawaii

Understandably, most visitors don’t come to Hawaii when the weather’s best in the islands; rather, they come when it’s at its worst everywhere else. This is the high season in Hawaii. During the high season, generally from mid-December through March or mid-April, prices are generally up; you can expect o pay top dollar for airfare, accommodation, rentals, etc.

Importantly, if you are planning a trip to Hawaii, make your reservations as early as possible as rooms are often booked to capacity.

Then there is the off-season. During this spring period, (mid-Apr to mid-June) and fall (Sept to mid-Dec), the island is less crowded and prices are lower.

If you are looking to save money, avoid the crowds and experience pleasant spring weather where the days are cooler, the waters are calmer and there is less rainfall., then this is the best period to visit Hawaii, especially May to March.
