On the morning of Kamehameha Day, a long line of riders on horseback passes through Honolulu draped in flowers, and the statue of the king in front of Aliiolani Hale disappears under braided leis. The trade winds are steady, the afternoons are bright, and the islands settle into their long summer. June suits beach days on the dry coasts, green waterfalls on the wet ones, and a calendar that finally lets you choose between islands.
What is the weather like in Hawaii in June?
June is warm and sunny almost everywhere in the islands, with dry leeward coasts like Maui and Kona, a few showers on Kauai, and a steady drizzle on the Hilo side of the Big Island.
| Place | Region | Average high (°F) | Average low (°F) | Rain (in) | Rain days | Sea (°F) |
|---|---|---|---|---|---|---|
| Honolulu | Oahu, south shore | 86.9 | 73.8 | 0.50 | 0.7 | 78.4 |
| Maui | Maui, dry side | 88.3 | 70.3 | 0.17 | 0.4 | 77.8 |
| Kauai | Kauai | 83.3 | 73.4 | 1.79 | 5.0 | 78.8 |
| Kona | Big Island, leeward coast | 85.2 | 74.0 | 0.76 | 1.7 | 80.4 |
| Hilo | Big Island, windward coast | 81.8 | 68.7 | 7.30 | 16.7 | 78.5 |
The big divide is the side of the island. Maui and Honolulu are close to rain-free, so a beach day is nearly a given, while Hilo sees showers on most days and keeps its waterfalls full. Kauai sits in between, with a shower now and then that rarely lasts.
Kona is the warmest place to get in the water this month, with the sea there a few degrees above the other islands. Nights are mild on the coasts and noticeably cooler in Hilo, where the air stays damp after dark. Daylight lasts well into the evening, which makes for long sunset dinners.
Where to go in Hawaii in June
Oahu: Honolulu, Waikiki and the south shore
Honolulu in June is dry and bright, with surf lessons lining Waikiki and outrigger canoes gliding out in the morning. This is the island for people who like a bit of city with their beach: shave ice, food trucks, Pearl Harbor and the ridge walk up Diamond Head. The North Shore, famous for winter giants, is far gentler now and more about shrimp trucks and snorkeling days than spectators on the sand.
Maui: Wailea, Kaanapali and the Haleakala summit
Maui is the driest and hottest of the reference places in June, which suits the resort beaches of Wailea and Kaanapali on the leeward side. Mornings on the sand turn into long afternoons of snorkeling, and evenings are clear enough for sunsets over Lanai.
The Haleakala summit is a world apart, cold and windswept before dawn, so a sweatshirt matters there even in midsummer. On the wet windward side, the winding Road to Hana is lush and full of waterfalls, and best treated as a full day of stops rather than a rush to the end.
Kauai: green cliffs and the two shores
Kauai is the island of green ridges, and June keeps it that way with a handful of showers that mostly pass quickly. Poipu on the south shore is the natural base for sunny beach time, and the north, around Princeville and Hanalei, trades a bit of extra rain for taro fields and mountains rising straight behind the bay.
The island is quiet by Hawaii standards, with fewer crowds and more room to wander. The Na Pali cliffs and Waimea Canyon reward a patient day of driving and short walks, and boat trips along the coast are a summer pleasure.
The Big Island: Kona, Hilo and the volcano
Sunny days define the Kona side, where the ocean is the warmest among the islands, and up on the hillsides overlooking town, the coffee farms stay cool and quiet. Snorkeling, boat trips and long coastal drives fill the days here.
Hilo is another story: wet most days, but that is what feeds the waterfalls and botanical gardens, and a rain jacket is all you need. Hawaii Volcanoes National Park, with Kilauea, is cool and misty at the crater rim, so plan layers and take the visit as a half-day outing from either coast.
What to do in Hawaii in June
Kamehameha Day on June 11
June 11 is a state holiday honoring the king who united the islands. Oahu’s parade winds through Honolulu with pa’u riders in flowing skirts, floral floats and hula halau, and the Kamehameha statue wears a mountain of leis.
The celebration is spread across the islands, with local festivals, hula and crafts on the Big Island and Maui too. It is a good day to see Hawaiian culture in a family setting, and banks and government offices close, so plan around that.
A hike up Diamond Head
The trail to the crater rim climbs 560 feet over 0.8 mile, with a view of Waikiki and the coastline at the top. Going early keeps the heat down, as June sun gets strong by midday.
It suits most walkers who are comfortable with stairs and a steady uphill, and you should allow 1.5 to 2 hours round trip. If you don’t live in Hawaii, you must have a reservation to get in and to park.
| Site | Open | Admission |
|---|---|---|
| Diamond Head State Monument | 6:00 a.m. to 6:00 p.m., last entry 4:30 p.m. | $5 entry, $10 per vehicle for parking (non-residents) |
Water days
With the sea in the upper 70s to around 80 degrees, snorkeling and paddling are comfortable without a wetsuit. Kona’s boat trips, Maui’s morning snorkel outings and Kauai’s coast cruises are all at home in June.
Humpback whale season runs from November through May, so June is the very end of it and sightings are unlikely. Dolphins, turtles and monk seals are protected, so admire them from a respectful distance.
Is Hawaii busy in June?
Yes, June is busy as school lets out across the mainland and family vacations begin, and the summer crowds peak into July.
Waikiki and Maui’s resort strips feel it most, with full beaches and booked-up rental cars. Kauai and the quieter stretches of the Big Island stay calmer, and Lanai and Molokai remain peaceful with few hotels and little traffic. Kamehameha Day adds local travelers to the mix on the weekend nearest the holiday.
What to pack for Hawaii in June
Light summer clothes cover most days, with a few extras for wet or high places.
- Swimsuits and a rash guard for long snorkeling days
- A light rain jacket for Hilo, Hana and the Kauai north shore
- A warm layer for the Haleakala summit and the volcano rim
- Reef-friendly sunscreen and a wide-brimmed hat
- Sturdy sandals or trail shoes for Diamond Head and waterfall paths
Good to know before you go
The Central Pacific hurricane season begins on June 1 and runs to November 30, so June sits at its very start. Every year hurricanes show up in the central Pacific, yet Hawaii does not usually see them, and a 1993 survey by NOAA done after Hurricane Iniki found that, between 1950 and the time of that report, just four had affected the state. Each island is its own rental car, since no car ferry links them, and short inter-island flights connect them instead.
Is June a good time to visit Hawaii?
Yes, June is a very good time, especially for beach lovers on Maui, Oahu’s south shore, Kona and Poipu, where the sun is nearly constant.
Compared with May, the days are a touch warmer, the sea a little warmer and the crowds start to build. July is hotter and busier still, with Hilo getting wetter and the sea slightly warmer again. June sits at a comfortable middle, with long evenings, the first summer swells on south shores and Kamehameha Day bringing leis, hula and a parade to the islands.
