The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for Barra da Lagoa over the next couple of weeks.
Right off the bat, we’ve got a few days of nothing to write home about. The surf is pretty much flat or junk through Wednesday the 22nd and Thursday the 23rd, with a mix of light rain, onshore winds, and a tiny, messy 2ft windswell that’s just not worth paddling out for. We’re looking at a bit of a dry spell until Friday morning.
Now, Friday the 24th is where things start to get interesting. The early morning is the standout for this first week. We’ve got a clean 6ft swell from the SSE, with a 10-second period. The wind is light and cross-offshore from the south, which should keep the waves clean. The combined energy is moderate at 669, so there’s a solid push. The water temp is about average for this time of year, so no surprises there. This is the best bet for the first week, but be aware this spot can get crowded often, so get in early.
The swell hangs around for the weekend, but the wind gets tricky. Saturday the 25th morning is still good with a 6ft SE swell and light NW winds, but the afternoon gets chopped up. Sunday the 26th and Monday the 27th are a write-off with onshore winds and weakening swell.
We then hit another quiet patch. Tuesday the 28th through to the end of the month and into early August only offer small, weak waves, mostly under 3ft, with very low energy – sometimes as low as 47. It’s just ordinary.
The real roaring action, if you can handle it, is for the first week of August. On Monday the 3rd, we’re looking at a massive 10ft ESE swell with a 10-second period. The combined energy is a very strong 1996, but the key warning here is that this is too big for this break. The comments say it’s too big, so unless you’re a real expert, give it a miss. The same goes for Tuesday the 4th with a 10ft, 12-second groundswell packing 2665 energy. That’s a lot of water moving, and it’s still flagged as too big.
Wednesday the 5th is the real standout for the whole forecast. The morning brings an 8ft ESE swell with an 11-second period, and the wind is light, cross-offshore from the northwest. The energy is very strong at 1633, but the conditions are rated as excellent for experienced surfers. This is the one to circle on your calendar. It’s big, but it’s clean. The swell direction is a good match for the break. Thursday the 6th keeps the quality going with a 7ft ESE groundswell, a very long 14-second period, and light cross-offshore winds. That’s a long period, which means the waves will have a lot of power and shape, but at a beach break like this, it can close out. Still, for the experienced crew, it’s a promising run.
So, to sum it up: the first week is a slow burner with one good morning on Friday the 24th. The second week has a massive, expert-only swell early on, but the real gem is Wednesday the 5th and Thursday the 6th, which are the best on offer for anyone with the skills to handle it.
Rusty.
