We compare the 7-day forecast to the last 5 years of marine data for the same week at Laniakea. The delta tells you whether conditions are shaping up better, worse, or about the same as a typical early July.
We score each day of the 7-day forecast using the same algorithm as the leaderboard, and highlight the highest scorer.
Open-Meteo's Marine API (swell height, period, water temperature) and Weather API (wind and conditions).
Honestly, no. Every break has tide windows, swell directions and reef contours that a global model cannot see. Treat the score as a starting point, then check a local cam.
The best week for surf at Laniakea is the week of 30 November (score 3/5) with low crowds.
Barely any swell. Not much to work with today. Heavy offshore making for difficult paddle-outs but textbook faces. Conditions improving through the afternoon. Not enough swell to get this spot firing properly.
Heads up: jellyfish: peak season, and rocks exposed at low tide.

The air here is 70% cleaner than the average comparison city right now.
Significantly cleaner air than a typical city. Ideal for outdoor exercise with minimal respiratory strain.
Not a pollutant. Ozone is naturally higher at altitude and near the coast, and lower in cities where traffic exhaust breaks it down. High readings here typically indicate clean air. Can cause short-term airway irritation during intense exercise but is not linked to the long-term health risks of particulate pollution.
Additive health score: each pollutant contributes points relative to its WHO 2021 guideline and long-term health impact (PM2.5 9, NO₂ 5, O₃ 3, PM10 2, SO₂ 1 at WHO limits). Data via Open-Meteo. City markers show live readings. Red line marks the WHO guideline. Updated 03:00

Laniakea is a powerful, remarkably long right-hand reef break on Oahu's North Shore, offering high-speed walls and occasional barrel sections along a sprawling volcanic coral reef. The wave demands elite paddle fitness just to maintain position in the line-up due to the powerful currents and the distance of the take-off zone from shore. Famous for the green sea turtles that haul out on the beach, Laniakea produces world-class right-handers when the North Pacific delivers.
North-westerly winter groundswells from November through February deliver the goods. The wave needs 6ft-plus of swell to properly activate the outside reef. The biggest days handle 12-15ft. Southerly or easterly trade winds provide offshore conditions. The wave works across the tide range but the inside bowl section is best on a lower tide.
The outside take-off zone sits far from shore over the deep reef section. The right peels for 100-200 metres, transitioning through multiple sections before finishing in the inside bowl. Position yourself well outside; the sets build slowly and break further out than expected. The deep-water channel on the east side provides the paddle-out route, though the distance is significant.
Powerful currents sweep across the reef, making position maintenance exhausting. The reef is shallow on the inside sections with exposed coral. Hold-downs on bigger days are serious. The distance from shore means swimming in after a lost board is a long, current-affected ordeal. Turtles rest on the reef and must be avoided. The paddle out is gruelling.
Limited roadside parking along Kamehameha Highway, which is heavily policed for parking violations. The beach access is straightforward but the paddle-out is long and demanding. No formal facilities at the beach. The North Shore towns of Haleiwa and Waialua provide services.
Laniakea is less crowded than Pipeline or Sunset Beach due to the demanding paddle and the powerful conditions required to activate it. Expect 10-20 experienced surfers on good days. The North Shore hierarchy applies. The demanding paddle naturally selects for fit, committed surfers.
Paddle fitness is the barrier to entry here. The take-off zone is far from shore and the current constantly pushes you out of position. A longer board (6'6" to 7'2") with extra paddle power is essential for both catching waves and maintaining position. Start paddling out earlier than you think; it takes longer than expected. The inside bowl section throws the best barrels on a lower tide but the shallow reef increases risk. Hawaiian etiquette applies: respect the locals, don't snake, and don't drop in.

View Best Time to Go →Combining historical conditions with school holiday crowd pressure to find the sweet spot.
The timing score combines two signals: historical conditions quality (how good the skiing or surfing typically is in a given week, based on 5 years of weather data) and crowd pressure (how many of this destination's feeder markets have school holidays that week).
Crowd pressure is weighted by each feeder country's share of visitors. If 40% of a resort's visitors come from France and France is on holiday, that contributes 0.40 to the crowd pressure score. Crowds can reduce the timing score by up to 35%, ensuring conditions still matter most.
Scores: 5 = great conditions with low crowds (the sweet spot). 4 = great conditions with moderate crowds, or good conditions with low crowds. 3 = average. 2 = below average conditions or very crowded. 1 = poor conditions or peak holiday chaos.
