The Lowdown

Alright, I’m gonna be straight with you – this is a tough stretch for Slip Point. The next couple of weeks are mostly flat or full of very weak, small, short-period windswell that won’t get you excited. The water is sitting at 54°F right now, which is 5°F colder than usual – that’s much colder than normal for this time of year, so you’ll want a thick hood and gloves.

Looking at the overall pattern, there’s a lot of days with no surf to speak of. From the get-go, Monday morning (August 31) is small and clean but only 2ft of west swell with a 9-second period, and the combined energy is a measly 59 – weak. That afternoon goes glassy with 2ft, but still very ordinary. Tuesday (September 1) is a write-off with onshore wind and tiny swell. Wednesday and Thursday (Sept 2-3) are completely flat. Friday the 4th shows a little pulse: 3ft from the WNW at 9 seconds, with glassy morning conditions and combined energy at 147 – still weak, but the best of a poor lot. It’s just very ordinary.

Then we hit another gap. Saturday (Sept 5) through to Monday (Sept 14) is mostly small, weak, or flat. The afternoon of Sunday the 6th has a 1ft WNW swell with a period of 13 seconds – that’s a long-period groundswell, but it’s tiny, and combined energy is only 81. Wednesday the 9th morning gives 2ft at 13 seconds with glassy wind and 115 combined energy, but again, small.

The one standout in the whole 16-day window is Saturday, September 12. That morning, Slip Point sees a 4ft west swell with a 12-second period, offshore east-southeast wind at 10 km/h, and combined energy of 464 – that’s moderate energy, and it’s the biggest swell of the period. The wind is cross-off, so it’ll be clean. This is your best bet, but it’s still just a 4ft wave, so don’t expect a heavy day. Keep in mind that the swell is coming from the west, and the optimum direction for this break is WNW, so it’s a bit off-angle. The afternoon that day goes marginal with cross-shore wind.

After that, Sunday the 13th afternoon has a tiny 2ft at 9 seconds with glassy conditions, but it’s weak. Then it’s flat again through to the end of the forecast.

Bottom line: the only real highlight is that Saturday morning, September 12. Everything else is small, inconsistent, and mostly flat. If you’re desperate, the Friday morning the 4th is also worth a look for a glassy, small wave session. For the rest, save your energy.
