Long-period NW groundswell is filling in nicely, with Polihale and Tunnels leading the pack at ★2.5 — both seeing 15-second sets and decent cross to cross-offshore winds keeping faces clean. Haleiwa is also waking up with the biggest jump overnight, though it's sitting at ★1.5 for now with light cross-offshore ENE flow. Swell is building through the next 24 hours across the board, so expect ratings to climb — check North Shore and Kauai's north-facing reefs over the next couple days as this thing fills in.
