Hawaii Weather in May

Averages By Month

May is the first month of the Hawaiian summer season and probably one of the best times to visit. Temperatures range between 70°F and 82°F, the water temperature has risen to 79°F, the number of rainy days (7 on average)has dropped further and the sun shines for 9 hours a day. It must added though that the weather on Hawaii is great all year round - it´s a tropical island after all!

It´s still pre-peak season so hotels and flights will be relatively cheap. Even though, you might find more visitors since in Japan they have Golden Week holidays over the first few days of May. Also, the Memorial Day weekend at the end of May might be busier. If you are in Hawaii on the 1st of May you will see locals celebrating the Lei Day.

Best Time to visit Hawaii

Based on the weather we can safely recommend any time of the year for a vacation in Hawaii. The sun will shine daily and trade winds will provide a refreshing breeze.

In Hawaii the weather has only two seasons. The warm, dry summer where the temperatures reach from 81°F to 89°F is called ’Kau’ and the winter which lasts from November until April is called ’Hooilo’. In the winter season temperatures reach from 68°F to 81°F and the trade winds are slightly stronger. This time of the year is ideal for surfers who love the higher waves.
