The Lowdown
Alright folks, Rusty here. We’ve got a long look ahead for Slip Point, and I gotta be straight with you—it’s mostly a flat spell. There’s a big gap right at the start, with no real surf on offer for over a week. From Tuesday the 11th all the way through to the morning of Thursday the 22nd of August, it’s a write-off. The wind is either onshore or just junk, and the swell is basically non-existent. You’d be wasting your time paddling out.
Finally, on the afternoon of Saturday the 22nd of August, we see a tiny pulse of life. A small W swell of 2ft sneaks in with a 9-second period. The combined energy is moderate (103), but the wind is cross-onshore and up to 9 mph, making it choppy. It’s still rated as poor conditions, so I wouldn’t get your hopes up.
Sunday the 23rd offers similar 2ft W swell (9s), but the wind gets worse in the afternoon—12 mph from the WNW making it properly choppy. Energy drops to about 80. Not worth a session.
Monday the 24th of August, the morning is the best we’ll see in this whole window. We’ve got a 3ft swell from the WNW, period bumps up to 8 seconds, and the combined energy hits a moderate 118. The wind is light and onshore from the NW, but it’s clean. It’s still rated as poor surf conditions, so it’s not going to be pumping, but it’s the most promising moment.
Into Tuesday the 25th of August, the morning brings a rare treat. The wind swings to the east at 6 mph, giving us cross-offshore conditions that are clean. There’s a 2ft WNW swell with an 8-second period, energy at 72. It’s described as surfable but very ordinary. Still, a clean wave at Slip Point is better than a choppy one.
Wednesday the 26th of August, the last day in the outlook, is similar: 2ft from the WNW, a 10-second period, energy at 72, and clean conditions with a light east breeze. Again, it’s surfable but very ordinary.
So, the standout? It’s a toss-up between the morning of Monday the 24th for the biggest wave height (3ft) and the morning of Tuesday the 25th for the cleanest conditions. I’ll go with Tuesday the 25th of August as the best bet. The cross-offshore wind and clean surface will make those small, very ordinary waves feel a whole lot better than they look on paper. Just don’t expect any barrels.
Stay patient, and keep an eye on the forecast. Things can change.
Rusty.
