Is the month of May a good time to vacation in Hawaii? We’ll examine the details, but I’ll quickly cut to the chase and let you know that May is one of the best times to go to Hawaii. The weather is generally good, occupancy is down and costs are relatively inexpensive.

 What’s the weather like in Hawaii in May?

May’s weather is usually quite nice. Daytime high temperature average in the low to mid 80s F. Nighttime temperatures only dip into the lower 70s F.

The average ocean temperature starts to warm up in May and is certainly pleasant enough for swimming. For more details see our article on Hawaii’s ocean temperatures throughout the year.

By May, average rainfall levels are dramatically lower as compared to the rainier winter months. The typical rain pattern in Hawaii is that most precipitation falls at night. Daytime showers are usually brief.

Here are the average rainfall levels by island for the month of May:

Kauai – 2.07 inches – This measurement is based on Lihue’s averages per Lihue is located on the southeastern side of the island and is not as wet as the North Shore, but not as dry as the South Shore.

Oahu – 0.99 inches – This average is based on Honolulu’s rainfall per North Shore rainfall will be a little higher, while Ko Olina’s rainfall will be slightly lower.

Maui – 0.74 inches – This average is based on Kahului’s rainfall per Kahului is where Maui’s main airport is, but it’s not typically considered a resort area like Wailea, Lahaina, Kaanapali and Kapalua. Kahului’s rainfall tends to be a bit higher than all the resort areas, with the exception of Hana on east Maui.

Hawaii, the Big Island – 0.71 inches – This average is based on Kailua-Kona’s weather per Kailua-Kona is a popular resort area. Further north on the Kohala Coast, the weather tends to be even drier with only about 10 – 12 inches of rain for the entire year! Hilo, on the east side of Hawaii Island, is another story though, with an average of 8.12 inches of rainfall for May per

Lanai – 2.17 inches – This average is for Lanai City in Lanai’s upcountry/highlands, which tends to get much more rain that the island’s sunny, beach resort at Manele Bay. Data sourced from

Molokai – 0.53 inches – This average, per, is for the airport just west of Kaunakakai town. Weather towards the east side will be rainier.


Is May a crowded time to visit Hawaii?

As a whole, May is one of the least crowded months to visit Hawaii. Though May is generally very uncrowded in May, there are a couple of minor exceptions worth mentioning.

  • Waikiki Beach can be a popular destination among Japanese people for Golden Week, which is a series of holidays starting April 29 and lasting through May 5/6. We have visited the islands during this time and we didn’t find them to be overly crowded.
  • Memorial Day holiday (the weekend including the last Monday of May) is a fairly popular time to visit.

The following chart from our Hawaii visitor data analysis shows the visitor arrivals to Hawaii per month. As you can see May arrivals are below average.

Have you been to Hawaii in May? Where did you go? How was your visit?

  1. May is my second favorite time to visit Maui, right behind September.
    I like the lack of crowds in those 2 months, and the weather is great – slightly more so in September.
    We’ve visited in March and June, and both were much more crowded, especially March, due to whale watching and Spring Break.
    March was also wetter than I like.
    May is great if you’re hoping for room upgrades at the resorts, because they have more openings, it’s easier to get dinner reservations, the beaches are less crowded, etc. The same for September.
    We were married in September on Maui, but my work and my wife’s garden make it difficult to get away in September, so May works best for us.
    But there is really no bad time to visit.
    We usually use points for hotels and miles for airfare, so the time of year is not so important when it comes to costs, although you sometimes get more out of your points/miles in these off-months.

  2. I have a 21 year old son in a wheelchair. need advice on the best places/sights to visit that are accessible and places to stay. He loves to snorkel and has a beginner dive certification.

      1. No. Just starting to look so any advice or guidance would be much appreciated. He has Friedrich Ataxia and uses a wheelchair but can transfer independently. Thanks!

        1. I try to make a mental note of accessible attractions whenever I visit Hawaii. Thankfully there are many! I think you can find great things to do no matter which one you choose from any of the four major islands — Oahu, Maui, Kauai, Hawaii (Big) Island. Take a few minutes to read through our how to choose the best island(s) for you to help direct you to the island(s) that resonate with you the most: After you look through that, comment to let me know which island(s) you’re leaning towards.

          Maui and the Big Island are our favorites for snorkeling, but you can find good snorkeling on the other islands, too.

  3. Thanks Sheila! I think we are leaning towards Maui after looking at everything. This is a bucket list trip for us and we have been saving for a while. Any pointers on good deals? I want Josh to get the most he can out of the trip and love that Hawaii offers beach wheelchairs! You are awesome! Thanks again so much for all of the good information.

    1. Here’s our 7-day Maui itinerary I believe a good portion of it can be enjoyed by all. You may have to do a little research on the accessibility of some of the sites and tours.For example, I wonder if you might be able to find a Molokini boat tour company that you can bring the wheelchair onboard for some mobility? I would check with Trilogy, Ali’i Nui and Pride of Maui first as they are very customer oriented. I took a quick glance on Pride of Maui’s FAQs and they do address bringing wheelchairs on board, though I’m not sure if it would suit your needs. Here’s that link:

      I wish I knew more to tell you about accessibility. I did come across these websites that may offer you some more information and ideas:

      We have a roundup of our best money saving tips here: Do you have a Costco membership? If so, we have found some of the very best packages for car and hotel on their travel website.

      Hope that helps!

  4. Thank you for such an amazing website!
    I’ve literally been binge reading all your posts.

    We’re planning our first ever trip to Hawaii during May and our tentative dates are May 4-May 17.
    We’re planning to do 3 islands during this trip
    Oahu 4 days, Maui 4 days and Big island 4 days.

    We’re travelling from Vermont, so keeping in mind the expenses.. we’re planning to pack as much as we can during this trip.
    What are your thoughts? Do you think this is a good enough time to spend on the 3 islands?

    Thank you once again.. appreciate your inputs!

      1. Thanks for the reply Sheila.
        We’ve changed our plans and we’re thinking of doing only Oahu and Maui.
        We’re still figuring out return flights because they’re getting really expensive and the stay in Maui is also pretty high. 🙁

  5. We are planning to visit Maui either the first week of May 2020 or first week of June 2020. Would either be better than the other? We weren’t sure if the first week of May would be busier than normal do to Golden week and also looks like the water may be a bit cooler for swimming and snorkeling than June although not cold by any means. But I imagine crowds begin to pick up in June?

  6. I’m wondering how the weather will be in Hawaii during the month of May this year ? Im passing through not stopping for long unfortunately. I’m always worried about air travel through the area flying in scares me with storms. I’ve landed a few times in bad weather there so always upsets my days.
    Does anyone know the forecast for this year yet?
