About Laniakea
Laniakea is a highly powerful, remarkably long right-hand reef break situated on the renowned North Shore of Oahu, Hawaii. The bathymetry features a sprawling, deeply terraced volcanic coral reef that extends far into the Pacific Ocean. This stepped seafloor intercepts massive north-westerly winter groundswells, causing the wave to build slowly before pitching over the shallower inside ledges. It requires a southerly offshore wind to groom the expansive wave faces. When conditions align, Laniakea offers a high-speed, endlessly workable wall that occasionally throws thick barrel sections on the inside 'bowl'. Due to the immense hydraulic power, the highly active and treacherous rip currents that sweep across the reef, and the sheer length of the ride, it is strictly an advanced surfing location. It demands elite physical paddle endurance to simply maintain position in the line-up, coupled with the technical proficiency to execute high-speed carving manoeuvres on thick, heavy wave faces.

How often is this page updated?
Current conditions refresh every 6 hours when the cron runs. Hourly data updates every 30 minutes. The 7-day forecast, luck factor, and packing notes are all pre-computed at the same time.
What is the luck factor?
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 late April.
How is 'best session' picked?
We score each day of the 7-day forecast using the same algorithm as the leaderboard, and highlight the highest scorer.
Where does the data come from?
Open-Meteo's Marine API (swell height, period, water temperature) and Weather API (wind and conditions).
Does the score capture local knowledge?
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.
