The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Balneario Sao Jose.
Right off the bat, we’ve got a bit of a slow start. The first week is pretty ordinary, so don’t get your hopes up too high. The real action, the one that’s got me talking, is way down the line on Monday the 27th of July. That morning, we’re looking at a solid 5 ft of swell from the ESE, and the energy reading is a massive 815 – that’s strong, punchy stuff. The wind is glassy, dead calm, so it’s going to be clean. That’s the standout session of the whole outlook, but it’s a long way off, so keep an eye on the charts.
Before that, we’ve got a few mornings that are worth a paddle. Wednesday the 15th of July has 5 ft from the SE with a clean cross-offshore breeze, and Thursday the 16th of July is glassy with 5 ft from the ESE. Both show clean conditions, but the energy is moderate (around 486 and 392). The water temp is sitting at 66°, which is about average for the time of year, so nothing weird there.
The surf drops off through the weekend into the following week. From Friday the 17th through to the 26th, it’s mostly small, knee-to-waist high stuff, with a lot of days where it’s just not worth getting wet. The wind is generally light and offshore some mornings, but the swell is tiny – under 3 ft – and the energy is low, often well under 200. There are a few glassy moments, like Sunday the 19th afternoon and Tuesday the 21st afternoon, but the waves are ordinary.
Come Monday the 27th, it’s a new story. That 6 ft ESE swell is the big one. The period is short at 7 seconds, so it’s a windswell, not a groundswell, but with glassy conditions it’ll still be fun. The energy is 815, which is strong. That’s the day to circle on the calendar. Tuesday the 28th morning looks promising too with 3 ft from the SSE on a 12-second period – a proper groundswell that’ll wrap in nicely – and glassy wind. The energy is still moderate at 388, but that long period will make for some nice, lined-up waves, especially if the tide is right.
Wednesday the 29th is also tidy. 4 ft from the SSE with a 13-second period – that’s long-period groundswell – and a clean cross-offshore breeze. The energy is 443, so it’s got some weight. The afternoon looks even better, with 4 ft and a 13-second period, glassy conditions, and the energy jumping to 701. That’s a very solid session.
So, to sum it up: the first week is a grind of small, ordinary waves. The real deal is on Monday the 27th of July for the biggest swell, and then Tuesday the 28th and Wednesday the 29th have the best combination of long-period groundswell and clean glassy or offshore winds. Don’t rush out for the first week unless you’re desperate for a splash.
Rusty.

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.
