Forecast for Big Island Leeward

Swell Summary

While surf will remain below High Surf Advisory levels along all shores this week, a trio of storm-force north Pacific lows will, or have already, generated mid- to long-period northwest to north swells that will arrive over the coming days. The first swell will arrive tomorrow and Wednesday, with peak open ocean swell heights approaching 5 feet. The second low will generate a similarly-sized northwest swell that should arrive by the end of the week. The third low is expected to develop later this week, and may produce a northwest to north swell that arrives in about a week or so.

Southern hemisphere storm systems are still sending some swell our way, and a small boost in long-period south swell energy is expected around mid-week. The trade winds will deliver a steady supply of short-period wind waves to east facing shores through the week.
