On a July morning in Princeville, the grass on the golf course holds the last of the night’s rain, roosters call from the edge of the bluffs, and the first surfers walk down toward Hanalei Bay with boards under their arms. Mountains behind the town wear a scarf of cloud, and the air smells of salt and wet plumeria. This is Kauai’s north shore in its gentler season, a month for ocean swims, long beach days and green valleys, with an easy pace for anyone staying on the bluff.
What is the weather like in Princeville in July?
July in Princeville is warm, green and a little damp: pleasant enough for the beach all day, with passing showers that rarely last.
| Month | Average high (°F) | Average low (°F) | Rain days | Sea (°F) |
|---|---|---|---|---|
| June | 83.6 | 68.1 | 14.2 | 78.7 |
| July | 84.8 | 69.3 | 14.8 | 79.6 |
| August | 85.9 | 69.5 | 14.7 | 80.2 |
Princeville sits on the windward north shore, so it gets more rain than the dry sunny resorts on the south and west sides of the island. Rain in July usually comes as short showers blown in on the trade winds, often at night or in the early morning, and a sunny hour tends to follow. Mornings are often bright and clear over the bluffs, which makes them the best time for walks and the beach.
Afternoons are warm but seldom oppressive, since the trade winds keep the bluff breezy. Heavy downpours are uncommon in summer, and the wettest weather of the year belongs to the winter months. Evenings stay mild enough for dinner outside in a T-shirt, perhaps with a light layer once the wind picks up after sunset.
Daylight lasts well into the evening, with about thirteen and a half hours around mid-month, so there is time for a late swim or a long sunset on the cliffs. Pack for sun first and a shower second: a hat, sunglasses and a thin rain jacket cover it.
Can you swim in Princeville in July?
Summer is when the north shore proves most welcoming for a long, comfortable swim, and yes, the sea is warm enough for it.
The big winter swells that make this coast famous with surfers usually fade by summer, and many north shore beaches are gentler in July. Often a top pick for beginner surf lessons, swimming and paddleboarding is Hanalei Bay, a broad arc of sand backed by mountains.
Anini Beach, a short drive west, is sheltered by a long reef and tends to be popular with families and snorkelers. Below the bluffs of Princeville itself, Pu’u Poa Beach sits at the foot of the resort area, a good place for a sandy morning.
Still, the north shore can surprise you. Currents and shore break can appear even in summer, and conditions change from one day to the next and from one beach to the next.
Check the flags and signs, ask the lifeguard on duty where there is one, and stay out when the sign says to. Bring a rash guard, mineral sunscreen and your own snorkel gear if you have it, and keep your distance from turtles and monk seals resting on the sand.
What to do in Princeville in July
July is a beach-and-green-valley month on the north shore. The ocean is the main event, and the rest of the day fills with short walks, farm stands and views that open up between showers. Late in the month, local summer events and county fair-style gatherings often appear around the island, though dates move, so ask where you are staying.
Summer fruit stands along the road to Hanalei sell papaya, bananas and fresh coconut, and a shave ice after the beach is the classic reward. Plate lunches, fish tacos and poke are easy to find in the little restaurants of Hanalei, and a picnic on the sand costs only the groceries.
Hanalei Bay and the town of Hanalei
From Princeville, you head down the hill and it takes just a few minutes to reach Hanalei, crossing a bridge with only one lane and passing taro fields nestled beneath steep green peaks. The bay is the center of the summer scene: swimmers in the morning, stand-up paddlers at midday, and families under the trees at the pier by afternoon. The old pier is a good place to watch the light change on the mountains.
In town, a handful of galleries, bakeries and food trucks line the main road. Go early for parking and a quieter beach, and come back for sunset when the clouds often turn pink over the water. It suits almost everyone, from toddlers digging in the sand to surfers waiting for a small summer set.
Anini Beach and the reef
Anini is a long, calm-looking strand a little west of Princeville, backed by ironwood trees and guarded by one of the longest fringing reefs in the islands. In July it is usually a good choice for snorkeling, windsurfing and kite lessons, with a wide, shallow lagoon near the shore. Families spread out on the grass, and the whole beach has an unhurried local feel.
Even in the lagoon, stay off the coral and keep an eye on the flags and the signs, since currents run near the reef channels. Bring water and snacks, since there is little for sale right on the sand. Mornings tend to be the clearest time for the water.
Bluff walks, Queen’s Bath and Hideaways
Right in Princeville, a narrow path drops from the bluff to Hideaways Beach, a small cove with rocks, reef and a view back up the cliff. The trail is steep and can be slick after rain, so good sandals or shoes matter. The pools of Queen’s Bath, farther along the shore, are a famous sight, and in summer the lava rock is often calmer, but waves here have a long record of catching visitors by surprise, so most people choose to enjoy the view from above.
For an easy morning, walk the edge of the golf course and the cliffs near the St. Regis, where the views stretch across Hanalei Bay to waterfalls streaming down the mountains after a shower. Bring a hat and keep to the paths.
A few more ideas round out the month: kayaking up the Hanalei River in the calm of the morning, a visit to the Kilauea Lighthouse and its seabird refuge, a boat trip along the Na Pali coast when the summer sea allows, and a round of golf with a view of the bay. Local rain is a reason for a farm stand stop or a gallery browse, not a reason to cancel the day.
A two-day itinerary for Princeville in July
Day 1 belongs to the beach and the bay. Start early at Hanalei Bay while the water is clear and the sand is quiet, with coffee and a pastry from a bakery in town. Swim and paddle until the sun climbs, then retreat for a plate lunch in the shade. Midday heat is the time for a rest or a stroll through the galleries of Hanalei.
In the afternoon drive out to Anini for snorkeling in the lagoon, then return to the bluff for a quiet hour. Dinner can be a casual fish plate or a table with a view in Princeville. Daylight lasts late in July, so a sunset walk along the cliffs is easy to fit in.
Day 2 starts on the water or on foot. Paddle the Hanalei River in the morning calm, or walk down to Hideaways Beach if the path is not slick from a passing shower. By late morning, drive to the Kilauea Lighthouse and its birds, then eat at a food truck or a farm stand nearby.
Afternoon is for a round of golf, a spa hour or a slow beach read. If rain settles in, shift to a gallery visit, a coffee shop or a long lunch indoors and wait for the break in the clouds. Finish with a dinner in Hanalei and a last look at the mountains in the evening light.
Is Princeville busy in July?
Yes, July is one of the busier months on the north shore, because summer vacation brings families from the mainland and the weather is most welcoming.
The weeks around the Fourth of July are the liveliest, with full beaches, busy restaurants and rental cars that go quickly. Hanalei parking fills early, and the popular tables book up in the evening. Later in the month it stays active but a little looser, especially on weekdays and at the less famous beaches.
For the holiday weeks, reserve rooms and rental cars well in advance, and for the quieter stretches, a little later. Restaurants with a view are worth reserving a few days ahead, while casual spots can be handled on the day. Boat trips along the coast also tend to fill up in summer, so reserve those before you arrive.
Early mornings are the best way to beat the crowds. A sunrise swim or a walk on the bluff is peaceful even in peak weeks, and the late afternoon often thins out once beach days end.
What to pack for Princeville in July
Pack light and think of water, sun and the occasional shower.
- A rash guard and mineral sunscreen, for long days in the sun and the sea.
- Water shoes or sturdy sandals, for slick bluff paths and rocky coves.
- A thin rain jacket, because showers come and go quickly.
- Snorkel gear, if you have it, for the lagoon at Anini.
- A hat and sunglasses, since the light is bright between clouds.
- A dry bag, to protect phones and cameras on the beach.
Good to know before you go
The Central Pacific hurricane season runs from June 1 to November 30, so July falls inside it. A rental car is the easiest way to reach Hanalei, Anini and the lighthouse, and summer weekends fill the small beach parking areas quickly. Lodging costs include state and county taxes on top of the room rate.
| Fee | Amount | Who pays |
|---|---|---|
| State Transient Accommodations Tax | 11.00% | Guests, on the gross rental |
| Kauai County Transient Accommodations Tax | 3% | Guests, on the gross rental |
Princeville in July vs June and August
Moving the trip to June gives a slightly cooler sea and air and a bit less crowding once the school year ends in the mainland states. The weather feels much the same, with showers on the trade winds, and the start of summer brings a calm, easygoing mood to the beaches.
August is a touch warmer, with the sea at its warmest of the three months and the beaches busy through the school break. It rains a little more, and the lush green of the valleys holds. Crowds usually thin toward the end of the month as families head home.
Families tied to school calendars will find July the easy choice, with the most settled summer feel. Travelers who prefer quieter beaches could look to early June or late August, while anyone who wants the warmest water should lean toward August.
Is July a good time to visit Princeville?
Yes, July suits beach lovers, families and anyone who wants warm water and long daylight on a green, dramatic coast.
Swimmers, paddlers and snorkelers will love it, as will travelers who enjoy a slow morning on the sand and a cliff walk before dinner. Those who dislike any chance of rain, or who want the big winter surf, should look at another month. The north shore is always a little wet, and summer is not an exception.
On arrival, head down to Hanalei Bay for a first swim and let the day settle. What is special about July here is the way the ocean softens: the same bay that roars in winter turns into a wide, warm place to float with the mountains above you.
