G'day, Rusty here. Let's have a look at what's in store for Balneario Sao Jose. The water's sitting at 68°, which is bang on average for the time of year, no surprises there.

To be straight with you, the first few days are a write-off. Friday the 3rd is a total dud with crossed-up wind and flat, weak energy – the combined swell energy is a paltry 111 (weak). Saturday the 4th is a bit better in size as it climbs into the 5ft to 5ft range from the south, but the wind is onshore and conditions are pretty average, a marginal call at best.

Alright, now for the bright spot. Sunday morning, July 5th is the standout. We've got a clean 5ft south swell, period a solid 12 seconds, combined energy of 724 (moderate), and the kicker? Glassy conditions, absolute dead calm wind. That's a real good session heading your way. This is the one to circle on the calendar for a proper crack.

Things get a bit mixed after that. The week of the 6th through the 10th is pretty inconsistent with small, weak swells mostly under 3ft, and often choppy or crossed-up winds. There's a little pulse on the 7th morning with a clean 3ft swell from the SSE under offshore NNW wind, but it's nothing to write home about. The 8th and 9th have glassy mornings, but the swell is only 3ft with combined energy in the 200s (weak).

The weekend of the 12th and 13th picks up a little. Sunday the 12th sees a 4ft swell from the SE, 12-second period, and offshore NNW wind in the afternoon. Clean, but small.

Now, heading into the second week, Saturday the 11th morning looks promising with glassy conditions and a 4ft SE swell, but it's still on the smaller side. Tuesday morning, July 14th is shaping up as another potential high point – a clean 5ft south swell, 12-second period, glassy calm. Combined energy of 663 (moderate). That’s a solid, clean wave.

Wednesday the 15th stays glassy in the morning with a 4ft south swell. Then Thursday the 16th morning is glassy with a 5ft south swell and combined energy of 525 (moderate). Friday the 17th morning, again glassy, with a 5ft south swell and 11-second period. And Saturday the 18th morning brings a clean 5ft SSE swell, 11-second period, cross-off wind, and combined energy of 771 (moderate). That's a solid end to the run.

Keep in mind, Swell heights pushing 5ft to 6ft on those later days are getting up there – fine for experienced surfers, but maybe a bit much for beginners.

So, in summary: Sunday the 5th and Tuesday the 14th mornings are your best bets for clean, fun waves. The rest of the window has its moments, but you've got to pick the glassy windows mid-week. Just don't bother with the first few days.

Stay stoked.

Information about the Balneario Sao Jose Surf forecast

The above surf forecast table for Balneario Sao Jose provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Balneario Sao Jose can be found by selecting the local surf guide option on the grey menu. Our Balneario Sao Jose surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Balneario Sao Jose) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Balneario Sao Jose may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
