Just past sunrise on an April morning in Princeville, clouds pull back from the Hanalei mountains’ green wall, and the bay turns a pale silver in the day’s first light. Roosters call from the roadside, surfers walk down to the water with boards under their arms, and the fairways of the bluff steam gently after a night shower. April is the tail end of the wetter season on Kauai’s north shore, which means waterfalls still running, taro fields shining and the island at its greenest.
What is the weather like in Princeville in April?
April is warm and green with frequent passing showers, mild enough for shorts and a light rain layer on the same day. The north shore sits on the windward side of Kauai, so clouds catch on the mountains behind town and drop rain in short bursts, while the sun keeps breaking through between them.
| Month | Average high (°F) | Average low (°F) | Rain days | Sea (°F) |
|---|---|---|---|---|
| March | 76.5 | 63.3 | 12.9 | 75.3 |
| April | 79.6 | 64.8 | 12.8 | 75.8 |
| May | 82.5 | 66.7 | 10.6 | 77.6 |
Mornings start cool and fresh, pleasant for coffee on a lanai with a light sweater. By midday the sun does the work and the air turns properly warm, though the trade winds keep it comfortable.
Showers tend to arrive as quick curtains that pass in minutes, and a rainbow over Hanalei Bay often follows. A real downpour that lasts the day is less common, and an inch of rain or more falls on only about one day in the month.
Evenings cool off enough that a long-sleeve shirt feels good at an outdoor dinner, especially near the bluff where the wind comes off the ocean. Days are long, with a little under thirteen hours of daylight in mid-April, so there is time for a morning on the water and an afternoon on a trail. Pack quick-drying layers rather than anything heavy, and expect trails to be muddy and the light to be soft and changeable, wonderful for photographs of the mountains.
Can you swim in Princeville in April?
Yes, the sea is comfortable for a long swim in April, warm enough that most people stay in without a wetsuit, though the surf on the north shore decides where and when.
April sits at the end of the big-wave season on the north shore, so swells can still roll in from the north and make some beaches rough, with strong currents and shore break. Other days the water is gentler, especially inside the reef-sheltered corners of Hanalei Bay and at pocket beaches below the bluff, where families wade and paddle.
How a beach is that day changes quickly, so read the signs at the sand, and let the lifeguards and the posted flags decide. At beaches without a lifeguard, stay on the shore if the waves look heavy.
Strong swimmers and surfers will find plenty to like, and snorkelers should look for a day with small surf and clear water. Nervous swimmers and young children do best on the calmest days and in the shallows. Bring a rash guard for the sun and a towel for the showers, and keep a respectful distance from any turtle or monk seal resting on the sand.
What to do in Princeville in April
April on the north shore is about green scenery, slow beach mornings and the last of the winter swells. Spring brings Easter weekend, and the week after Easter the Merrie Monarch hula festival fills Hilo on the Big Island, so many hula halau across the islands, Kauai included, are rehearsing.
Dates move with Easter, so the timing shifts from year to year. Watch for hula performances, lei stands and craft fairs in the north shore towns, and for the gentle spring mood of locals out on weekend mornings.
Humpback whale season is winding down by April, and you may still spot a few from the bluff or from a boat, but they are fading with each week rather than guaranteed. Bring binoculars and look for spouts and tail slaps offshore in the early morning, when the sea is flattest.
Hanalei Bay and Hanalei town
A short drive down the hill from Princeville, Hanalei is the north shore’s gathering place, a curve of sand backed by mountains with a pier at one end and a surf break at the other. Mornings are best for walking the beach and watching surfers paddle out, when the light is soft and the crowds are thin. In April the mountains behind the bay are streaked with waterfalls after the winter rains.
In town, look for shave ice, fish tacos, plate lunches and fruit stands, plus small galleries and surf shops in the old plantation-style buildings. The taro fields along the road into town glow bright green and make a good photo stop. It suits almost everyone, from families to couples, and a sunny gap between showers is the moment to walk the pier.
Coastal walks and beaches below the bluff
Princeville itself is a clifftop community, and its best moments are the paths and overlooks along the edge. Short trails drop to small beaches tucked beneath the bluff, with tide pools, lava rock and turquoise water on calm days. In April the paths can be muddy and slick after rain, so wear shoes with grip rather than flip-flops.
Go in the morning, when the air is cool and the light skims the cliffs, and treat the water with respect, since swells can arrive without much warning. These walks suit anyone who likes scenery over activity, and they pair well with a swim on a calm day and a picnic lunch.
Golf, spa days and easy afternoons
Princeville is known for its golf courses, set along the cliffs with views of the mountains and the sea, and April’s mild temperatures make a round comfortable, with showers passing quickly. When rain sets in, resort spas, long lunches and browsing the shops at the Princeville center fill the gap.
For food, expect fresh fish, poke, coconut and tropical fruit, plus coffee and baked treats at small cafes. Evenings call for a sunset drink at a resort terrace, with the sky changing color over the ocean when the clouds part.
A two-day itinerary for Princeville in April
Day 1 starts early with coffee and a walk along the bluff, when the air is cool and the first light catches the mountains. Head down to Hanalei Bay for a beach morning, a swim if the flags and lifeguards say the water is friendly, and a stroll along the pier. Lunch is a plate lunch or fish tacos in Hanalei town, eaten at a picnic table or on the sand.
In the afternoon, when clouds often build over the hills, wander the galleries and shops in town and stop for shave ice. Return to Princeville for a late-day walk on the clifftop paths, then settle in for dinner with a view and watch the sky turn orange over the ocean. If rain sets in, a spa treatment or a slow meal indoors makes a good card.
Day 2 begins with a round of golf or a quiet walk down to one of the small beaches below the bluff, whichever suits you, while the morning is still cool. Look out to sea for any late whales, and bring a light rain jacket in case a shower sweeps through.
Spend midday at a resort pool or a cafe, then use the afternoon for photography on the quiet roads around the taro fields or a relaxed browse of the Princeville shops. Finish with an early dinner and a sunset stroll along the edge of the bluff. On a wet day, stay indoors for a long lunch, a spa visit and a lazy afternoon with a book.
Is Princeville busy in April?
Princeville is moderately busy in April, with the winter crowds thinning but spring break and Easter weeks still bringing families and couples from the mainland.
Holiday weeks around Easter and school breaks are the busiest stretches, when rooms, rental cars and dinner tables go first. The weeks outside them are calmer, and Hanalei and the beaches feel relaxed, especially on weekday mornings. Reserve your room and rental car well ahead when your trip lands on Easter or a spring break, though you can wait a bit longer if you come during the calmer weeks.
Restaurants in Hanalei and Princeville fill in the early evening, so a reservation for dinner is a good habit on weekends. Popular north shore sights can draw a crowd by late morning, so an early start helps. No park or trail reservation is required this month, so check the official state park notices before you plan a day around one.
What to pack for Princeville in April
Think light, quick-drying and ready for a shower, with one warmer layer for evenings.
- Pack a light rain jacket, since most days bring passing showers.
- Shoes with good grip, since bluff paths and trails are muddy.
- Swimsuit and rash guard for sun and sea.
- A long-sleeve shirt or sweater for breezy evenings.
- Mineral sunscreen and a hat for bright breaks between clouds.
- Binoculars for any late whales offshore.
Good to know before you go
April falls before the Central Pacific hurricane season, which runs from June 1 to November 30, so the main weather matters this month are showers and north swells. Having a car makes the short hops between Princeville, Hanalei and the beaches easy. Book lodging first, then a car, then dinners. Lodging is subject to the state and county accommodation taxes below.
| Fee | Amount | Who pays |
|---|---|---|
| State Transient Accommodations Tax | 11.00% | Guests, on lodging |
| Kauai County Transient Accommodations Tax | 3% | Guests, on lodging |
Princeville in April vs March and May
Going a month earlier brings more rain, with March the wettest of the three, and a somewhat cooler feel. The sea is about the same temperature, but north swells are usually larger and more frequent, so beach days are more hit or miss while the big-wave scene is at its peak. Whale watching is also better in the earlier weeks.
Going a month later brings warmer air, fewer rainy days and a sea that is a touch warmer, which makes May easier for swimming and beach time. The north shore swells calm down as summer approaches, and the whales are gone. The landscape is still green, but trails are drier and the days feel more settled.
Choose March if you want big surf and a better chance of whales, and May if you want gentler water and more sunshine. April sits between them, with a bit of both, and suits travelers who like a green island, a mix of swell and calm and a relaxed pace.
Is April a good time to visit Princeville?
Sure, April suits travelers who enjoy lush scenery, gentle weather and a laid-back north shore, and who take the odd shower as part of the deal.
It suits hikers and photographers, golfers, couples and families who want warm air without summer heat, and anyone who enjoys watching the sea change from day to day. Travelers who want guaranteed sunshine and flat water for snorkeling may prefer a leeward coast or a later month, since the north shore can still be rainy and its surf unpredictable.
On arrival, check the beach conditions and lifeguard flags first, then plan the day around the weather, saving the clifftop walks and Hanalei for the clearest hours. What makes April here memorable is the light, with waterfalls still pouring down the mountains, rainbows over the bay and a sea that is warm enough to enjoy once the swells allow.
