The Lowdown
Alright folks, Rusty here. Let's have a look at what's on offer at Playa de Gros over the next couple of weeks.
The pattern kicks off a bit slow. Monday and Tuesday are pretty ordinary, with small swells and iffy winds, so we’re not getting fired up just yet. The real story starts to build from midweek and shapes up into a solid run.
The water is sitting at a very warm 74°, a whopping 4° above normal, so you’ll be in boardshorts or a spring suit at most.
Wednesday the 9th we see a bump in size, with chest to head-high 6ft swell out of the NW, but it’s coming with rain showers and a cross-onshore breeze. The combined energy is a moderate 537, but it’ll be a bit lumpy, not the cleanest.
Now, the first real standout comes on Thursday the 10th morning. We get a clean 4ft NW swell, 10-second period, and it’s flat calm – glassy conditions. That’s a proper window. Combined energy is a solid 355, and with zero wind, it’ll be an absolute joy. This is the pick of the first week for sure.
Friday and Saturday drop right off into tiny knee-high slop, so we have a quiet patch to start the second week. Worth noting the combined energy dips as low as 43 on Saturday morning.
But then, Sunday the 13th morning slams the door open again. A powerful 5ft NW groundswell with a 13-second period hits, and it’s glassy again. The combined energy is a strong 905, and the wave comment is "expect very good surf conditions". This is a serious session, but for a beach break like Playa de Gros, that long period groundswell can make it a bit tricky, sometimes a bit too straight. Keep an eye on the tide.
Monday the 14th morning is another good one, a clean 4ft with 12-second period and glassy conditions. Combined energy sits at a meaty 494. This is a solid follow-up day.
The next big tick comes on Wednesday the 16th morning: 4ft NW, glassy, 485 energy. Good, clean fun.
Then we get another absolute belter on Thursday the 17th morning. Wait, scratch that, the whole week has more. The next beauty is Saturday the 19th morning. This one is a standout for the more experienced crew. We’re looking at a solid 6ft NW swell with a 13-second period and a clean, cross-offshore breeze. The combined energy is a very strong 1037, and the conditions are described as excellent for experienced surfers. At this size and with that period, it’s not for beginners, but the crew will be frothing.
The run closes out nicely with Sunday the 20th afternoon being glassy and clean, and Monday the 21st looking good with glassy conditions and consistent 4-4ft NW swell.
Rusty.
