Forecast for Big Island Windward and Southeast

Forecast for Big Island Leeward

Swell Summary

The current long period northwest swell will remain steady today, hovering near low end High Surf Advisory (HSA) thresholds. The current HSA was extended in time through this afternoon for most north and west facing shores of the smaller islands. Surf heights are forecast to fall just below advisory thresholds by this evening as the swell period continues to decline. A small north swell will also linger through the day today before fading by tonight. A series of reinforcing long period northwest swells will arrive this week, likely bringing north and west shore surf back into advisory levels from Thursday through Friday before gradually declining over the weekend.

South and east shore surf will remain on the small side, with east shore surf building from Tuesday into next weekend as trade winds strengthen over and upstream of the island chain.
