Hawaii – North & South Shore Action

A pair of Northwest swells are forecast to arrive this week, along with a pair of South swells, making for fun conditions in both Town and Country. Looking North, an overhead Northwest swell is forecast to build through Wednesday (3 feet at 12.4 seconds 320°). Increasing Northeast trade winds will also be producing wind swell in the 8-second range.

Both components peak on Thursday, but look for the trades to stick around into the weekend. The Northwest swell fades into Saturday, but another pulse begins to fill later that afternoon.

Sunday’s Northwest swell isn’t as big, and is slightly more West (2.6 feet at 12.4 seconds 310°), but it will produce some fun waist to head-high surf at the top spots. The trade swell continues to decline into the beginning of next week.

Long-period SSW energy begins to show on the SSW of Hilo, HI buoy on Wednesday (2 feet at 16.6 seconds 195°) and builds into Thursday. The swell height is nothing substantial, but the 16-second swell period should give it some oomph.

The swell peaks at 2.6 feet at 14.9 seconds on Thursday, then tapers off into the weekend. A Southerly (181°) reinforcement builds Sunday into Monday, with energy in the 14-15 second range, and swell heights forecast to hit 3-feet. Look for conditions to be biggest late Sunday to early Monday, depending on swell travel time to your location.

Definitely enough action in the forecast to keep both sides of the Island happy. Thursday’s Northwest pulse will likely be biggest, but the SSW swell will pump waves at Town for a few days. The Monday morning dawn patrol could also be rewarding, stay tuned to the forecast to see how things shape up over the weekend.
