Forecast for Big Island Leeward

Swell Summary

Small pulses from the west-northwest to north will maintain small surf along north and west facing shores through early next week. The largest of these swell is slated for this Friday. A series of south swell is set to roll in through early next week. One of the two of the larger pules is due in tonight with a period of 16 seconds. The second pulse is a long 19 second period slated to arrive Sunday. This swell is likely to produce a significant increase in surf heights along south facing shores, just in time for the 4th of July celebration. Strengthening trade winds mean the surf along the east will be on the rise, but staying below high surf advisory. Certainly the waters will be becoming dangerously rough and choppy, especially over the weekend.
