The Lowdown

Alright, folks, it’s Rusty here. Let’s have a look at what’s coming up for Balneario Sao Jose.

Right off the bat, we’re looking at a pretty flat start. The first few days are basically a write-off with tiny, weak dribble. From Tuesday the 21st through Thursday the 23rd, we’ve got waves around 2ft to 3ft from the east, but the period is a short 8 seconds, so there’s just no push or power behind it. The combined energy is weak, sitting between 67 and 129. It’s surfable, but honestly, it’s very ordinary. If you’re desperate for a paddle, Tuesday morning and Wednesday morning are clean with light offshore winds, but don’t expect much.

Now, things start to get interesting from Friday the 24th. That’s when we see a proper bump in energy. The swell picks up to 4ft from the south-southeast with a period of 9 to 10 seconds, and the combined energy jumps to 326 – that’s moderate energy, real waves. The wind is offshore from the north-northwest on Friday morning, going glassy by the afternoon. That is your first standout window. Saturday the 25th morning is also looking good with clean 4ft surf from the same direction. These are the best options on offer in the first week.

We do get a bit of a lull through Sunday and Monday, with the swell dropping back but the energy still decent. Sunday arvo brings a longer period of 12 seconds from the south at 5ft, but the wind is cross-onshore, so it’s a bit messy. Monday morning, the 27th, is glassy with 3ft from the southeast and a 9-second period, but it’s a smaller day.

The second week is a bit of a mixed bag. There’s another promising little pulse around Tuesday the 29th with glassy conditions and 3ft from the east, but it’s short period. The real standout for the long range is Wednesday the 5th of August. We’ve got a very long period groundswell of 15 seconds from the south, with 3ft of swell. That’s a classic south swell, and with glassy conditions in the morning, it could be magic. The combined energy is 305, so there’s juice in the water. Keep in mind that a long period swell like this (over 15 seconds) can be a bit tricky on a beach break – it might break a little too straight – but it’ll be clean and have plenty of push. That’s your second standout, but it’s a fair way out, so don’t book the week off just yet.

Water temperature is sitting at 67°F, which is pretty much bang on average for this time of year, so no surprises there.

This spot is a beach and pier setup, exposed to the south-east. For the days with bigger swell and poor winds, like Sunday the 26th afternoon with 5ft and cross-onshore wind, it might look more interesting for the kite crew than for paddle surfing.

Otherwise, keep an eye on Friday the 24th and Saturday the 25th for the best of the early action, and then cross your fingers for the 5th of August.

Rusty.
