The Lowdown
G’day, Rusty here. Let’s be straight with you: the next couple of weeks are a bit of a mixed bag for Playa de San Lorenzo. We’ve got a few clean mornings, but a whole lot of nothing in between. The good news is that the ocean isn’t completely flat – there’s some life in it – but you’re going to have to pick your moments.
Looking at the start of the run, Thursday the 13th has a bit of a pulse. The morning session is looking like the pick of the early days, with a clean 2ft of WNW swell rolling in. It’s not big, and the energy is moderate (131), but the wind is glassy, and that makes it all worth it. The water is sitting at 71°, which is a touch warmer than normal for this time of year – a nice little bonus. The afternoon stays clean but it drops off, so get it while you can.
Friday the 14th is similar – small and clean in the morning with 2ft, but the energy is weakening (90). It’s surfable, but you won’t be writing home about it. Saturday the 15th is a write-off; we’ve got a bit more swell (3ft) but the wind goes cross-onshore and it’s all over the place. Not worth your time.
Sunday the 16th is interesting. The swell picks up to 4ft from the NNW, and the energy jumps to 237, but the period is a short 7 seconds. That makes it a bit crumbly and less powerful. The morning is glassy, so there’ll be some clean-ish waves, but it’s not going to be great. Monday the 17th is back to the small stuff (2ft) with clean morning conditions, but again, it’s just ordinary.
Then we hit a dead zone. From Tuesday the 18th through to Wednesday the 19th, the swell drops right out. We’re talking 0.7ft to 1ft and very weak energy. The wind is cross-onshore and it’s just not worth paddling out. This is a few days of flatness, so don’t bother.
Now, here’s where things get a bit more interesting. Thursday the 20th sees a big pulse of swell arrive – 6ft from the NNW with a period of 11 seconds. The energy is strong (933), which is a big jump. The wind is light and onshore, though, so it’s going to be a bit messy. It’s marginal at best. Friday the 21st, though, is a standout. The swell settles to a solid 5ft, still from the NNW with a 9-second period, and the morning is glassy. The energy is strong (587) and the waves should have some push. This is the best morning of the whole run up to this point. The afternoon gets a bit onshore, so get out there early.
Saturday the 22nd sees the swell drop back to 3ft with a period of 8 seconds and moderate energy (221). The morning is clean, but it’s just ordinary. Sunday the 23rd is mostly flat again, so another gap.
Monday the 24th gives us a small, glassy morning with 4ft from the NW, but the energy is only moderate (225). It’s surfable, nothing more.
Then we get to the second week, and there’s a promise of something better. The standout for the whole period is Tuesday the 25th. We’re looking at a solid 7ft of WNW swell with a period of 8 seconds, and the morning is glassy. The energy is strong (628). This is the biggest, cleanest swell of the run. It’s got some punch, so it might be too much for the beginners, but for the intermediate crew, this is your day. The afternoon gets a bit cross-onshore, but the morning is the one to chase.
After that, the swell backs off again. Wednesday the 26th and Thursday the 27th have some small, clean mornings (4ft to 4ft) but the energy is moderate. It’s just not that exciting.
Finally, Friday the 28th brings another promising morning – 4ft from the NW with a 10-second period and glassy conditions. The energy is strong (473). It looks clean and should offer some good ones, but the afternoon gets blown out by a stronger cross-onshore breeze.
So, the long and short of it is this: if you want waves, focus on Friday the 21st for a clean, solid swell, and Tuesday the 25th for the biggest and best morning of the whole two weeks. Both have the right conditions – light wind and clean faces. The rest is a waiting game.
Rusty.
