The Lowdown
Alright folks, it's Rusty here. Let's talk about what's coming up for Playa de Somo. The picture is a mixed bag for the next couple of weeks, but there's a light at the end of the tunnel, and it’s got some serious size.
Right now, we're looking at a run of small, weak surf. For the first week and a half, it’s honestly pretty quiet. From Monday the 17th all the way through to about Tuesday morning the 26th of August, there’s nothing that will get you out of bed. The waves are tiny, mostly under 3ft, and the energy is low. We’re looking at combined swell energy numbers barely ticking over 100 (53 to 161). It's flat, plain and simple.
Thursday morning the 20th does see a small uptick with a 3ft NNW swell and glassy conditions, but it’s still pretty ordinary and the energy is only moderate (226). Not a standout.
The first real sign of life comes late in the period. Thursday morning the 27th of August sees a slight pulse to 4ft from the NW with glassy winds, but the energy is still only moderate (161).
But hold onto your board shorts, because the real magic is the stand-out window at the very end. Friday morning the 28th of August is when things get real. We’ve got a solid 8ft NW groundswell, with a period of 9 seconds, and the combined energy jumps to a strong 1019. The best part? The wind is glassy from the west. This is where the experienced crew will be licking their lips, because at over 8ft on the Friday afternoon it is strictly for the experts.
Then, the true highlight of the whole 16 days is Saturday morning the 29th of August. This is the one to circle. We’re looking at a massive 13ft NNW groundswell with a long period of 13 seconds. The combined energy is a beastly 5866. With glassy WSW winds, the conditions are described as excellent for experienced surfers. This is a big, powerful swell, best suited for a point or reef, but if you’ve got the skill, Playa de Somo could fire. The afternoon is going to get blown out by onshore winds, so it’s a morning mission only. Remember this is nearly two weeks out, so while it looks incredible, treat it as a promising but still uncertain forecast.
The water is sitting at 73°, which is a touch warmer than what you’d usually expect for this time of year.
Alright, that’s the long-range call. Keep an eye on that last weekend of August. Rusty out.
