The Lowdown
Alright folks, Rusty here. Let's have a look at what Balneario Sao Jose has in store for us over the next 16 days.
Right off the bat, the first week is a bit of a struggle. We’ve got a whole bunch of days with tiny, weak swell and onshore winds, so you can pretty much write off the next week for anything decent. The water temp is sitting at 67°, which is pretty average for this time of year, so no surprises there.
Now, after that dry spell, things start to get a little more interesting. The first real standout comes on Saturday, August 1st. We wake up to a glassy morning with 0.3m (roughly 1.0ft) of easterly swell, but it's short period at 7 seconds and combined energy is weak (397). It's not a world-beater, but it'll be the best wave of the week so far. Get on it early before the wind swings around.
The real highlight, and the one to circle on your calendar, is Tuesday, August 4th. It’s another glassy morning, this time with a 2ft southerly groundswell (0.7m). The period jumps up to 13 seconds, giving it some real push and combined energy is moderate (229). A glassy morning on a longer period swell at this beach and reef setup is about as good as it gets for this stretch. The cross-on seabreeze will spoil the afternoon, so get your session in early.
Looking further out, Wednesday, August 12th starts to look promising, but it's a long way off. We’re seeing a building 5ft southerly groundswell (1.5m) with a 15 second period hitting that afternoon – combined energy is strong (1173). The wind is a light cross-on, which is a bit of a letdown, so keep an eye on it.
Thursday, August 13th is another one to watch in the long range. A 5ft south-east swell (1.6m), 10 second period, with glassy conditions all morning. That's a legitimately good wave size and clean conditions. Combined energy is strong (865). This one is for the experienced crew, as it’s getting up there in size, but for the experts, it’s the best looking swell of the entire forecast if it holds.
So, to sum it up: mostly flat and windy for the first week, then a couple of small, clean windows that are worth a paddle. The real excitement is in the second week, with two solid, clean mornings to aim for the 13th of August.
Rusty.
