The Lowdown
Alright, this is Rusty, giving you the lowdown for Playa de Lastres. Let’s see what we’ve got.
The next week and a half is pretty grim, I won’t lie. The models are showing a whole lot of flat, small, and messy conditions for most days. There’s a real dry spell until the final few days of the month and into September.
Looking at the details, Monday the 17th has a tiny 2ft NW swell but the wind is glassy in the morning. It’s not enough to get excited about, the energy is weak (44) and the surf is poor. That sets the tone for the next week. We go through Tuesday with 1ft, Wednesday with 0.7ft, just nothing doing. The water temp is sitting at 72°, which is a touch warmer than normal for this time of year, so at least it’s nice to be in the water.
There’s a small bump on Thursday the 20th morning with a 3ft NNW swell and a period of 11 seconds, giving us moderate energy (312), but the conditions are still poor, so it’s a miss. Friday the 21st is a bit better, we get glassy conditions and a 4ft to 5ft NNW swell, but it’s still just ordinary, nothing to write home about. The energy is moderate (378). Saturday the 22nd is clean but small, around 3ft.
For the next few days, it’s back to poor, small surf until Monday the 31st of August. That’s when things get interesting. The morning of the 31st is looking like the standout. We’ve got a 3ft swell from the NNW but check out the period – 17 seconds! That’s proper long-period groundswell energy, and the combined energy is a very strong 1217. The wind is glassy. This will be clean, lined-up waves for those who know the river mouth setup at Playa de Lastres. Remember, a super long period like this can make those beach break lines straighten out a bit, but with the offshore here, it could be special.
Then Tuesday the 1st of September morning is the biggest call of the forecast. A solid 8ft NW swell, with a period of 14 seconds and a combined energy of 2068 – that is very strong. Wind is light and cross-offshore, making it clean. That’s a heavy day though, over 8ft is expert territory, so it won’t be for the faint-hearted. The afternoon picks up a 19 mph cross-onshore wind which will chop it up, so get your session in before lunch.
For the best on offer, I’m looking at the morning of Monday the 31st for the clean, glassy, long-period energy, and then the morning of Tuesday the 1st of September for the biggest, cleanest swell of the run, though it’s a serious one for experienced surfers only.
Stay patient, get those dawn sessions in.
