Things to Do

When the Weather Turns on the North Shore

Last updated

Rain on Oʻahu's North Shore comes in squalls, not days. What to do when it does, and what to do on the worse problem: a big swell that closes the water.

Start with the thing that will save you a wasted decision: rain on the North Shore is almost never a reason to cancel a day. It arrives as squalls — fifteen or twenty minutes of hard, warm rain blowing through on the trades, then sun. December is the wettest month at roughly two and a half inches, and June and July are comfortably under an inch. There is no grey season here. If you are standing in Waikīkī looking at cloud over the Koʻolau and wondering whether to drive up, drive up.

What is true is that the Koʻolau slopes a mile inland are substantially wetter than the beach strip, so a downpour over the mountains can silt up the water at stream mouths for a day or two without a drop falling on the sand. If you are here to snorkel, rain matters for visibility rather than for comfort.

The genuinely difficult day on this coast is a different one, and it usually happens under a clear blue sky. From roughly November to March, a big north swell closes the ocean. Lifeguards shut Waimea, Ehukai and Sunset, the reef at Pūpūkea is unenterable, and the entire reason a lot of people drove up here is suddenly a spectator sport. That is the bad-weather day the North Shore actually has, and most of this page is really about it.

The honest position on indoor options: there are very few. This is thirty miles of two-lane road with one large resort, no shopping mall, no cinema and no museum quarter. The genuinely sheltered things on this coast can be counted on one hand, and two of them are ticketed. If it is raining hard and you want to be indoors all day, the correct answer is often to drive somewhere else — the south shore is frequently dry when the North Shore is wet, and Honolulu has the indoor capacity that this coast does not.

What is left is better than that sounds, though. Waimea Valley is a rainforest walk that is arguably improved by rain. The Polynesian Cultural Center at Lāʻie is the one place up here built to absorb a whole afternoon and evening. Haleʻiwa's shops and galleries are covered. The Kahuku trucks do not care about weather and neither does a queue under an awning. And watching a serious winter swell in the rain is, if anything, more memorable than watching it in sunshine.

Our picks

The ones we would book

  • Editor's Pick

    Best booking for a wet or closed day

    Why we chose it

    Waimea Valley. A paved, gently graded walk up a botanical valley that is genuinely better in warm rain than in flat midday sun, with the canopy taking the edge off a squall. Adult admission has recently been in the mid-twenties. The one thing rain may cost you is the swim at the falls, which lifeguards close when the stream is running hard.

    Cheapest way to salvage an afternoon

    Why we chose it

    Dole Plantation on the freeway route home. The shop, the pineapple-cutting demonstration and the ice cream are under cover and free to walk into; the train and the maze are low-teens tickets each and both are outdoors, so skip the maze if it is actually raining. It costs no detour, which is the whole argument for it.

What rain actually does here

The pattern is squalls on the trade winds, not frontal systems. A shower blows in off the ocean, rains hard for fifteen or twenty minutes, and moves on. Half an hour later the sand is dry. Locals do not reschedule around it and neither should you.

The numbers, as monthly bands rather than promises: December is wettest at around two and a half inches, January and February are close behind, and the totals fall away through spring to a low in June and July of comfortably under an inch. Even in the wet months the rain is concentrated into short events rather than spread through the day.

Two complications worth knowing.

The mountains are wetter than the coast. The Koʻolau range behind this strip catches substantially more rain than the beaches do, which is why the valleys are green and the shoreline is not. A heavy night on the ridge sends brown water down the streams, and at Waimea, Anahulu and the smaller gulches that muddies the nearshore water for a day or two. If you planned to snorkel, check what the last twenty-four hours of rain did rather than what the sky is doing now.

Rain closes the waterfall pool, not the valley. Swimming at the falls in Waimea Valley depends on lifeguards having the pool open, and stream conditions after rain are exactly what closes it. The walk stays open; the swim may not.

The one weather event that does stop a day is wind on the shoulder of a tropical system. Central Pacific hurricane season runs from June to the end of November, direct hits on Oʻahu are rare, and a system passing to the south more commonly delivers several days of unsettled conditions and closed water under otherwise fine skies.

The genuinely sheltered list, which is short

The Polynesian Cultural Center, Lāʻie. The only place on this coast built to hold a full afternoon and evening, with six island villages, a canoe pageant and a theatre show. A good deal of the site is outdoors, so it is shelter with caveats rather than an indoor day, but the show and the dining are under cover and it absorbs weather better than anything else up here. Closed Sundays, recently Wednesdays too, plus Thanksgiving, Christmas and New Year's Day. Check the calendar first: a rainy-day plan that arrives at a locked gate is worse than no plan.

Haleʻiwa town. A few hundred yards of covered shopfronts: galleries, surf shops, board-shaping rooms, small food places. Not a mall, and it will not hold four hours, but it holds one or two and it is the only concentration of roofs on the coast.

Dole Plantation, Wahiawā. On the freeway route above Haleʻiwa, so it is on the way home rather than a detour. The shop, the pineapple-cutting demonstration and the ice cream are under cover; the train and the garden maze are not, and a wet maze is a miserable maze. Grounds admission is free.

Turtle Bay. The resort's restaurants and public spaces are open to non-guests and are the coast's only reliable wet-afternoon sit-down, and its bar runs later than anywhere else up here.

The food trucks. Kahuku's shrimp stands and the cluster across from Shark's Cove operate through squalls with awnings and a queue. A wet lunch under a tarpaulin with a plate of garlic shrimp is a perfectly good forty minutes.

That is the list. There is no cinema, no aquarium and no shopping centre on this coast, and any guide that implies otherwise is padding.

Things that are better in the rain

Local tips

Waimea Valley. The main path is paved and gently graded, the canopy takes the edge off a squall, and a botanical valley in warm rain is a genuinely better experience than the same valley at midday in August. The stream runs harder and the collection looks like what it is. The one thing to check is whether lifeguards have the falls pool open, because stream conditions after heavy rain are exactly what closes it. Adult admission has recently been in the mid-twenties.

Watching surf. Rain does nothing to a forty-foot face. Ehukai Beach Park, Waimea Bay's lot and the cliff above it, and the long stretch at Sunset are all as good wet as dry, and there are markedly fewer people. Bring a rain shell rather than an umbrella, which the trades will destroy.

Puʻu o Mahuka Heiau. A short level path on the ridge above Waimea, and the view down over the bay under moving cloud is better than under flat sun. It is free, it takes twenty minutes, and it is an active sacred site — stay outside the enclosure walls and do not touch the offerings.

The drive itself. The windward coast road through Kāneʻohe, Kualoa and Lāʻie is at its best with cloud sitting on the Koʻolau wall and waterfalls running down it, which only happens when it has been raining. If a wet morning has wrecked the beach plan, this is the day to do the long route.

Haleʻiwa's shave ice. Contrarian, and correct. The queues are shorter and the shops are covered.

Wet-weather odds by month

When to go

Rain here is short and frequent rather than long and rare, so these are odds on being rained on at some point in a day rather than on losing the day.

  • December. Wettest month, roughly two and a half inches, with squalls most days and the biggest surf of the year. Plan a land itinerary and treat any swimming as a bonus.
  • January and February. Close behind December for rain and at the peak for swell. The two months where a rainy-day list is genuinely needed.
  • March. Easing, but still winter more often than not on the water. Spring break crowds.
  • April and May. Rain falls away quickly, from around two inches in March to well under an inch by May. The ocean usually opens during April.
  • June and July. The driest months of the year, comfortably under an inch each, with hard reliable trades. A wet day here is a rarity.
  • August and September. Still dry, with the warmest water of the year. September is the strongest month on this coast for most people.
  • October. Rain begins to return and the first north swells often arrive in the second half. Still one of the two quietest months.
  • November. Wetter again, the surf season turns, and the Triple Crown waiting period opens. Conditions can change inside a week.

Across every one of those months, the same advice applies: check the surf forecast for the north shore of Oʻahu before you check the weather. On this coast the swell decides more days than the rain does.

The real bad-weather day: a closed ocean

Before you book

This is the day that actually disrupts a North Shore trip, and it usually looks beautiful.

From roughly November to March, north swell arrives in pulses that build over a day and run for two or three. When it does, Honolulu Ocean Safety closes beaches and flies red flags, and the water at Waimea, Ehukai, Sunset and Pūpūkea is simply not available. Shark's Cove, which is shallow, sheltered snorkelling in August, is a place people are swept off the rock ledge in January. The Waimea shorebreak breaks adult collarbones in water you can stand up in. None of this is weather in the sense a forecast app means it.

Red flags and closures are not advice. If lifeguards have shut the beach, the answer is no, and the tower will tell you plainly if you ask.

What to do instead. Waimea Valley. The Polynesian Cultural Center. The heiau. Haleʻiwa town. The Kahuku trucks. Kualoa Ranch down the windward road. Dole Plantation on the way home. And the thing most people end up doing, which is standing on the sand for two hours watching the ocean do something they have never seen before.

Where you can still swim. The sheltered coves beside Turtle Bay at the northeastern corner, the protected end of Kawela Bay, and Mālaekahana near Lāʻie are the realistic options, and even those depend on the day. Otherwise the south shore is on the other side of the island's swell window and is frequently calm on the same day.

How to see it coming. Read a surf forecast for the north shore of Oʻahu the evening before. Big swells are called days out. In winter that forecast tells you whether the beaches will be open at all, which makes it more useful than any weather forecast you could read.

Driving out of the weather

How they compare

Oʻahu is small enough that the weather on one coast frequently has nothing to do with the weather on another. If a wet or closed day has ruined the plan, moving is a legitimate answer.

WhereDrive from HaleʻiwaWhy it helps
South shore and WaikīkīAbout 55 minutes over the topOften dry when the North Shore is wet, and on the opposite side of the winter swell window — swimmable when this coast is closed
Kāneʻohe and the windward coast45 to 70 minutes down Route 83Byōdō-In Temple, Kualoa, and the drive itself at its best under cloud on the Koʻolau
Wahiawā and the central plain20 minutes up Route 99Dole Plantation, and it is on the way home anyway
Honolulu properAbout an hourThe island's actual indoor capacity: museums, galleries and a genuine choice of restaurants
Leeward sideOver an hour via H-1The driest corner of the island, though the Kaʻena end of it is only reachable on foot from here

Two caveats. Leaving the coast in the middle of a wet morning means driving back up in the evening, so it works better as a change of plan for the whole day than as a two-hour excursion. And the freeway route through Wahiawā queues in the commuter peaks in both directions, so an eleven o'clock departure beats a four o'clock one.

The other option, which experienced visitors use, is simply to wait. A squall on this coast lasts twenty minutes. Buy a coffee in Haleʻiwa, sit in the car, and the beach will be dry before you have finished it.

Straight answers

Questions people actually ask

Does it rain a lot on Oʻahu's North Shore?

Not in the way visitors expect. Rain here arrives as squalls on the trade winds — fifteen or twenty minutes of hard warm rain, then sun — rather than as grey days. December is the wettest month at roughly two and a half inches, and June and July are comfortably under an inch. Nobody should cancel a North Shore day for rain. The Koʻolau slopes a mile inland are considerably wetter than the beach strip.

What is there to do indoors on the North Shore?

Very little, honestly. The Polynesian Cultural Center at Lāʻie is the one place built to hold a whole afternoon and evening, though much of it is outdoors and it is closed Sundays and recently Wednesdays too. Haleʻiwa town's galleries and surf shops hold an hour or two. Turtle Bay's restaurants are open to non-guests. Dole Plantation's shop is covered. There is no cinema, aquarium or shopping centre on this coast.

Is Waimea Valley worth visiting in the rain?

Arguably it is better. The main route to the falls is paved and gently graded, the canopy blunts a squall, and a botanical valley in warm rain looks like what it is. The one thing rain may cost you is the swim: lifeguards close the falls pool when the stream is running hard after heavy rain, and that decision is made on the day. The walk itself stays open.

What should you do if the surf is too big to swim?

Treat it as the North Shore's real bad-weather day and switch to the land itinerary: Waimea Valley, Puʻu o Mahuka Heiau, Haleʻiwa town, the Kahuku trucks, the Polynesian Cultural Center, Kualoa Ranch, Dole Plantation. Then spend an hour watching the ocean from the sand at Ehukai or Waimea, well back from the waterline. For actual swimming, the sheltered coves by Turtle Bay or a drive to the south shore.

Is the weather different on the North Shore than in Waikīkī?

Often, yes. Oʻahu's coasts sit on different sides of the Koʻolau range and the swell windows are opposite, so the North Shore can be wet while Waikīkī is dry, and the North Shore's water can be closed by a north swell on a day the south shore is glassy. It is about fifty-five minutes between them on the freeway route, which makes moving a legitimate response to a bad morning.

Can you still see the turtles at Laniākea in the rain?

Usually, yes — the turtles are not troubled by a squall, and there are often fewer people at the pull-off. The stop is a dirt shoulder on the mountain side of a fast two-lane highway with no facilities, so wet weather makes the crossing worse rather than the viewing. Keep to the ten-foot distance NOAA asks for, keep the stop short, and if the pull-off is full, keep driving.

When is the wettest time of year on the North Shore?

December, at roughly two and a half inches, with January and February close behind. Those are also the months of the biggest north swell, so they are the weeks when a wet-weather plan is genuinely useful. The driest months are June and July, comfortably under an inch each, with hard reliable trades. Even in the wet months the rain comes in short bursts rather than spread across the day.
