The Lowdown
Alright folks, Rusty here. Let’s look at what’s coming our way.
Straight up, the first few days are a write-off. We’re looking at a bit of a flat spell right now, so don’t bother paddling out until the weekend. The real action doesn’t kick off until Saturday the 5th of September, so you’ve got a couple of days to sort out your gear.
The standout session, and the one I’d be circling in red, is Saturday morning the 5th of September at Playa de Gros. The swell is a clean 3 ft from the NW with a period of 9 seconds, pushing a moderate combined energy of 249. The wind is a light cross-offshore from the ENE at 6 mph, which is going to keep the surface clean. The water is sitting at 74°, which is much warmer than normal for this time of year, so ditch the wetsuit. This spot is a beginner-friendly beach break, and it’s very consistent. Keep in mind, crowds are often here, so get out early.
After that, the next best look is Thursday the 10th of September. The morning session at Playa de Gros is showing a 4 ft NW swell with a 11-second period (moderate energy at 361) and glassy conditions with a light ENE breeze. The afternoon holds similar quality with a 4 ft NW swell and glassy NNE wind. It’s a clean, solid day for a longer session.
Friday the 11th of September morning is also worth a mention. Glassy conditions again with a 4 ft NW swell, 9-second period, and moderate energy at 251. It’s well worth a paddle if you’ve got the free time.
The second week gets a bit more ordinary. The swell is smaller and the wind tends to be more cross-onshore. There’s a brief window on Tuesday the 15th of September morning with a glassy 2 ft NW swell, but it’s weak. And again on Wednesday the 16th of September morning, there’s a glassy 3 ft NW swell, though the energy is low.
Overall, the best bet is the Saturday morning session, with Thursday the 10th as a solid backup. Don’t expect much from the second week unless forecasts change.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
