In Kona, as a June morning begins, the lava fields behind town take on a dusty gold in the first light, and the fishing boats are leaving the harbor. By the time the coffee is poured at an oceanfront café on Alii Drive, the sun is already warm on the seawall and snorkelers are wading in. June here is dry, bright and easy, a month for long days on the water and slow evenings with the sunset over the Pacific.
What is the weather like in Kona in June?
Kona in June is warm, dry and sunny, with mornings that start bright and afternoons that stay comfortable at the beach. Because the volcanoes block the moisture, the leeward coast lies in their rain shadow, which means rain seldom falls and does not last long.
| Month | Average high (°F) | Average low (°F) | Rain days | Sea (°F) |
|---|---|---|---|---|
| May | 83.9 | 72.7 | 1.8 | 79.5 |
| June | 85.2 | 74.0 | 1.7 | 80.4 |
| July | 86.1 | 74.9 | 1.3 | 80.9 |
Days are warm enough for shorts and a swimsuit from breakfast on, and evenings stay mild enough to eat outside without a jacket. Nights hold on to the warmth of the day, so you can leave the windows open or sit on a lanai after dinner. The sun is strong at this latitude, and the light is long, with daylight stretching past thirteen hours in mid-June.
When rain does come, it is usually a quick passing shower, often in the afternoon or at night, and it tends to clear fast. The wet weather belongs to the other side of the island.
Hilo, on the windward coast, gets far more rain through the year, and the high slopes of Hawaii Volcanoes National Park are cool and often damp. If you plan to drive across the island, bring a layer and expect the sky to change as you climb.
June also marks the start of the Central Pacific hurricane season, which runs from June 1 to November 30. Hawaii is rarely hit, but it is worth watching the forecast if you travel later in the season.
Can you swim in Kona in June?
In June, Kona’s ocean is warm enough that you can swim for a long, comfortable stretch, and most folks remain in the water for as long as they please. Snorkel masks come out early and stay out until the afternoon.
Summer is the calmer season on west-facing shores, and the Kona coast is usually gentler than in winter. Kahaluu Beach Park, Magic Sands and the sheltered coves along Alii Drive are popular for snorkeling, with turtles often seen near the rocks.
Manta rays, dolphins and reef fish sometimes show up on boat trips and night snorkels. Conditions still change from day to day, and a south swell can bring surf to some beaches, so the beach signs and the lifeguards decide whether it is a good day for the water.
Families often start at the shallow, sandy spots, while confident swimmers head for the reef edges. Bring a rash guard, a snorkel set and a mineral sunscreen, and keep your distance from turtles and monk seals, which are protected. Rinse off afterward, since the salt and the sun add up over a long afternoon.
What to do in Kona in June
June is a month for the water and the early hours. Kamehameha Day on June 11 is the big date, a state holiday marked with lei draping on the statues of the king, parades and hula across the islands. In Kona the day carries extra weight, since this is the coast where Kamehameha spent his later years, and the mood in town is festive, with families gathering at the parks and along the water.
Kona is also home to the Kona coffee belt, and a June visit pairs well with a morning in the green hills above town. Farms pour tastings on shaded porches, and roasters in town sell beans by the bag. Fruit stands along the road sell what is ripe, and the farmers markets in Kailua-Kona fill with flowers, honey and local produce.
Snorkeling and boat trips on the Kona coast
The reefs near Kailua-Kona are the reason many people come. Kahaluu Beach Park is the easy starting point, a protected-feeling bay near town where fish crowd the rocks and turtles often graze in the shallows. It is best in the morning, before the wind picks up and the parking fills.
Boat tours leave from the harbor for the cliffs and coves farther south, and many head to Kealakekua Bay, known for its clear water and the white monument to Captain Cook on the far shore. Evening trips go out for the manta rays, which gather under lights after dark. These outings suit confident swimmers and curious kids alike, and the flat summer mornings are the best time to go.
Kailua-Kona town and Alii Drive
The waterfront of Kailua-Kona is a good place to spend an easy afternoon. Hulihee Palace, a former royal retreat of lava stone, and the small Mokuaikaua Church, among the oldest in the islands, sit along the main road. Beyond them, Alii Drive runs along the shore past tide pools, cafés and shops selling shell jewelry and aloha shirts.
Late in the day, people gather on the seawall to watch the sun drop into the ocean, and the restaurants fill with grilled fish, poke and shave ice. The town feels relaxed in June, with fishermen cleaning their catch at the pier and kids jumping off the rocks.
Pu’uhonua o Honaunau and the South Kona coast
South of town, the road winds through coffee country to Pu’uhonua o Honaunau National Historical Park, a place of refuge on the shore where wooden figures stand beside carefully fitted lava walls. Walk the grounds slowly and keep off the stones, which are sacred to Native Hawaiians.
The tide pools beside it are a pleasant stop, and the nearby snorkel spots draw people looking for quiet water. Combine this with a coffee farm and a lunch at a roadside stand for a full day away from the main strip.
If you want to stay on land, the long lava coast to the north, with its white beaches at Hapuna and Kua Bay, is a good morning trip. Shade is scarce, so go early and pack water. When clouds roll in, the local museums, galleries and coffee roasters make an easy plan B.
A two-day itinerary for Kona in June
Spend midday walking Hulihee Palace and the church, then slip into the shade for lunch, since the sun is strongest at this hour.
Spend the afternoon at a small beach or browsing the shops along the waterfront. Stay for sunset on the seawall, then book an evening manta ray snorkel or a simple dinner of fresh fish at a harborside restaurant. Long daylight means you have time for all of it without rushing.
Day 2 heads south through the coffee belt. Stop at a farm for a tasting in the cool morning air, then continue to Pu’uhonua o Honaunau National Historical Park and walk the grounds before the heat builds. Eat lunch at a roadside stand or a small local café nearby.
In the afternoon, take a boat to Kealakekua Bay or snorkel from the shore at a quiet cove, then head back for a casual dinner. Should a shower appear, rare for this area, head instead to a roastery, a gallery or a farmers market, and hold off on the water until the following clear morning.
Is Kona busy in June?
Kona is moderately busy in June, with family travelers filling the coast as school lets out on the mainland. The beaches and boat tours see steady traffic, but the island is rarely crowded the way peak winter weeks can be.
Kamehameha Day brings local families to the parks and a festive feel to town, and the week around it can be livelier at beaches and restaurants. Rooms and rental cars are easiest to find if you book early, especially for the holiday weeks and for travel at the start of summer break. Later in the month, plans can come together closer to the date, though popular boat tours and dinner tables still fill up.
Early mornings are quiet almost everywhere, and the best snorkeling spots are calmest before the day-trippers arrive. Evenings along Alii Drive are lively but never frantic. Plan the busiest outings, such as manta ray trips and sunset dinners, a little ahead of time, and leave afternoons loose for the beach.
What to pack for Kona in June
Pack for sun, salt water and warm nights, with one layer for the drive uphill.
- Because the sun stays intense from morning to night, pack mineral sunscreen and a wide-brimmed hat.
- A rash guard and snorkel gear, for long hours in the water.
- Water shoes, for rocky entries at tide pools and coves.
- A light jacket, for cool air on the slopes and for breezy evenings.
- A refillable water bottle, for shadeless lava coast walks.
- Sandals and a light cover-up, for evenings on Alii Drive.
Good to know before you go
June opens the Central Pacific hurricane season, which runs from June 1 to November 30, so keep an eye on the forecast if your plans stretch later in the year. With a rental car, you can easily check out the coast and the coffee belt, plus boat tours and manta ray trips should be reserved ahead of time. Lodging taxes are added to the bill and are shown here for planning.
| Fee | Amount | Who pays |
|---|---|---|
| State Transient Accommodations Tax | 11.00% | Guests staying in hotels and rentals |
| County of Hawaii Transient Accommodations Tax | 3% | Guests staying in hotels and rentals |
Kona in June vs May and July
Going a month earlier, in May, brings slightly cooler air and a sea just a touch less warm, with similar dry weather. The crowds are lighter before school lets out, and Lei Day on May 1 brings its own garlands and hula to the islands. It suits travelers who prefer a quieter coast and do not mind a slightly cooler dip.
July is a little hotter and a little drier, with the warmest sea of the three months. Family travel peaks as summer vacation hits full swing, so beaches and restaurants fill and rooms are harder to find. It suits those who want the longest stretch of warm water and do not mind the company.
June sits in the middle, with Kamehameha Day as its own highlight. Choose May for the fewest people, July for the warmest water, and June if you want the holiday spirit with settled weather.
Is June a good time to visit Kona?
Kona shines in June, above all for visitors seeking sunny days, balmy water and a laid-back shore. Snorkelers, families, coffee lovers and anyone who enjoys long evenings by the sea will find it easy to love.
It is less ideal for those who want cool mountain air or green, rainy landscapes, since the leeward side stays dry and bright. If you prefer a quiet beach, head out early and choose smaller coves over the main strip.
On arrival, book the boat trip or manta ray snorkel first, since those fill up, then leave the rest loose. What makes June special in Kona is the combination of Kamehameha Day, flat summer mornings on the reef and sunsets that linger well past dinner.
