The Lowdown
Alright, let me tell you about what's cooking for the one truly serious wave in this whole forecast.
The window kicks off with some heavy, pure groundswell pumping in, and this spot, Shipstern Bluff, is the only show. It's a true big-wave reef, only for advanced guys. The water temp is sitting at about 55°F, which is roughly a degree warmer than normal for this time, so nothing too strange.
The first big highlight is Sunday, August 23rd, in the afternoon. You've got an 8-foot SSW swell running with a 16-second period, carrying a massive amount of wave energy (3920). That is deep, long-period groundswell. The wind is a clean cross-offshore from the west at 9 mph. This is a standout, but it's a monstrous wave. Experts only.
Tuesday, August 25th, is a smaller but still viable window. The morning brings a 6-foot SSW swell with a 12-second period and light cross-offshore winds from the northeast at 6 mph. The afternoon gets clean with a 5-foot swell and true offshore wind from the north at 6 mph. Wave energy is moderate (740). It’s smaller, but still a heavy paddle.
Look at Sunday, August 30th, in the afternoon. That’s when a huge 12-foot SW swell with a 14-second period shows up. The combined wave energy is absolutely massive at 9486. It’s windy, with a fresh 19 mph cross-offshore from the west-northwest, but it stays clean. That’s a true beast of a day. It'll be a circus for the tow crews.
September 1st has another solid morning. A 8-foot SSW swell, 14-second period, with a light 9 mph cross-offshore. That’s the kind of day you set an alarm for if you're a big-wave charger.
There's a fair gap after that with smaller, choppier, or wind-ruined days from September 2nd on, until a couple of scruffy-looking days pop up.
The standout in the whole run is the afternoon of August 30th. That 12-foot, long-period swell with clean winds is the main event. The afternoon of August 23rd is a close second with that incredible 16-second period. This is not beginner territory, and if you’re not sure, don’t even think about it.
