What's the weather like in Hawaii in May

By the time May starts in Hawaii, the weather is warm, dry and absolutely irresistible. Considered the first month of the annual dry season, May is well known for offering visitors long days filled with sunshine, especially on the westerly and more southern parts of the archipelago.


Those who visit these tropical islands in May can expect an average of eleven hours of sunshine every day, which will then continue throughout June and July.  While average temperatures are expected to reach a very welcoming 25°C.

In the peak period of the day expect average highs of approximately 27°C. However temperatures have historically reached record levels of a very hot 33°C at this time of the year. This means it is always wise to be prepared for some very warm weather.

Even if you are used to tropical conditions, sun protection is vital to ensure a comfortable stay in Hawaii. Even at night, average low temperatures do not usually fall below 22°C which means some relief from the heat will be necessary. 

As May is considered the warmest month of the year outside the hurricane season, it is the ideal time to visit this part of the United States, yet the beaches and towns are never as busy as they are in the peak summer months.

Sea Temperature

Even the sea temperatures are warm and inviting offering an average of 25°C which is only two degrees below the average peak conditions every year.


Rain levels are also forecast to be at one of their lowest levels of the year in May, only beaten by August when it comes to enjoying the driest weather of the year. Throughout the whole 31 days only 18 days are expected to experience any rain, with only an average of 38mm of rainfall for the entire month. This means more of that beautiful sun is able to shine, offering everyone the perfect Hawaiian climate.

Hawaii Beaches in May

Waikiki Beach Walk

Waikiki Beach is probably one of the most popular and most well know beaches in the entire Hawaiian archipelago and one of the best. From its miles of beautiful soft sand and tempting waters to the wealth of shopping opportunities and bars and restaurants. This is an area that never sleeps, to ensure people of all ages want to come back again and again. The beach itself provides ample opportunity to try any type of water sport, while on the sand there is still plenty going on. And if that's not enough there are always the events at Waikiki Beach Walk to keep everyone out of the midday sun. It's fun, it's exciting and it's busy every day of the year. No visit to Hawaii is complete without a trip to Waikiki.

On the island of Maui, the Ka'anapali Beach is the most popular beach in town. And while it is not patrolled like Waikiki, the water is still very enticing. Take a walk down to the beach and there are excellent spots for snorkelling and surfing alike. But mainly people come to Ka'anapali to sit, lie back and take in the view. The clear blue water means it is even possible to see bathing turtles from the shore at times. And with plenty of bars and restaurants lining the beach, you can come to Ka'anapali Beach in the morning and stay well into the next day. 

Bars and Restaurants

Hard Rock Café in Honolulu

There's no place in America where you can't find a Hard Rock Café, and that doesn't change in Hawaii. Hard Rock Café in Honolulu offers everything you would expect from this highly popular brand, all with a little Hawaiian influence. The food is fabulous, the atmosphere is classical American, where nothing is ever too much trouble. And with open air dining ensuring everyone can make the most of the May sun, it's a great place to be. For families, couples or just on your own. Everyone gets a warm welcome at the Hard Rock.

Kinaole Grill Food Truck

For something a little more down to earth, enjoy a meal at the Kinaole Grill Food Truck on Maui. Though the truck may not seem the most attractive place to eat on the island, the food is incredible and the prices are out of this world. Check out their Facebook page to see the menu of the day. Then head down to Kamaole Beach and taste their wares. Regulars such as spicy garlic shrimp and pulled pork are always enticing, but the Calamari is something that is truly inspired. And the best thing about the truck is that it is in the same place every day, so you can go back over and over again, enjoying fresh new flavours with each order.

Kualapu'u Cookhouse

On Molokai, the best place to experience some traditional Hawaiian cuisine is undoubtedly at the Kualapu'u Cookhouse. Though it doesn't look that special from the outside, the flavours of the food, the warm welcome and the healthy portions ensure everyone is completely satisfied. And the prices are pretty special too! The local atmosphere is friendly and inviting and the BYOB policy means you always have what you want to drink. Eat inside or enjoy some May sun with a little alfresco dining experience. Though the menu is varied, the Loco Moco is out of this world. You just won't be able to wait until it's time to come back for more.

Things to do in Hawaii in May

Island Helicopters

Stay or visit the island of Kauai and a trip to the Na Pali Coast State Park is a must. An area of outstanding natural beauty, with private beaches and beautiful scenery, no one can fail to be amazed. For the more active visitor, there are plenty of hikes and walking treks around the area to keep your blood pumping, or boat tours for the entire family. But for the best way to see the area, book a helicopter trip with Island Helicopters. The friendly pilot will share his in-depth knowledge of the region and take in the most advantageous viewing points. It's the perfect way to see the most of Kauai and have a once in a lifetime adventure.

Honolulu Zoo

One of the most popular things to do in Hawaii, is take a trip to Honolulu Zoo. It offers a fabulous alternative to the usual beach and surf type trips and lets everyone get up close and personal with some of the most beautiful animals in the world. The interactive experiences provide an understanding of what is happening to the local wildlife, while the high quality gift shop enables all visitors to buy some very unique mementos. As the sun warms up in May, make sure you take lots of water and sun protection with you. And try to avoid searching for the animals in the mid-day sun, many will seek shade inside, and it would be wise for the visitors to do the same.
