The Lowdown
Right then, let’s have a look at what’s coming our way. The outlook for Playa de Gros is a bit of a mixed bag, with a definite standout window to aim for.
We start off on Thursday, 20th August, with a 4ft to 5ft NW swell, but it’s pretty rough. The wind is cross-on or onshore, kicking up small wind ripples, so it’s not a great time to paddle out. The water here is sitting at 76°, which is much warmer than usual for this time of year, so that’s a nice bonus if you’re just floating around.
The next few days are a real struggle. Friday the 21st has a bit more size at 6ft, but the wind is straight onshore and it’s raining, so it’s washed out. The combined energy is high (680), but it’s all for nothing with the conditions. Saturday the 22nd starts clean with a 4ft NW swell and a cross-off breeze, but the swell is weak. By the afternoon, the wind swings and it gets choppy. Sunday the 23rd is tiny, down to 2ft, and the swell period is a short 7 seconds, so it’s just not worth it. The energy is almost nothing (54). From Monday the 24th through to Tuesday the 25th, the swell completely dies. We’re looking at flat spells with almost no energy, just a few pathetic ripples. That’s a solid 3 to 4 days of nothing.
Then, on Wednesday the 26th, we get a little pulse of life. A 4ft WNW swell with a clean, cross-off breeze. The energy is back up to 210, and it’s surfable. But the real gem is the first week of September. Thursday the 27th has a glassy morning with a 5ft WNW swell, and then the afternoon really lights up. The swell jumps to 7ft, the period is a solid 9 seconds, and the wind goes glassy. The combined energy is a massive 792, and it’s described as very good surf conditions. That’s the highlight of the whole forecast.
The standouts here are the afternoons of Thursday the 27th of August and the morning of Tuesday the 1st of September. The 27th gives you a 7ft groundswell from the WNW with perfect glassy conditions. The 1st of September is similar, with a 6ft NW swell, an 11-second period, and glassy morning winds. The energy is huge (821). This is proper, clean, powerful surf. It’s a bit big for beginners, but for anyone with a bit of experience, that’s your window. The 5ft to 7ft range on the 27th afternoon and the 1st morning is the best you’ll see, and with glassy wind, it’ll be absolutely dreamy. The rest of the time is mostly wind-affected or too small, so don’t waste your energy on those days.
