The Lowdown
Alright, folks, Rusty here. Let’s take a look at what’s on the menu for Guarita over the next couple of weeks.
We’re looking at a pretty quiet start. The first few days are a write-off, with only small, weak, onshore-affected waves. Nothing worth paddling out for. Towards the end of the first week, things start to build, but it's not until the second weekend that we see the real potential.
The standout session is hands down Sunday morning, September 13th. We’ve got a solid 8 ft swell from the SSE, with a long 12-second period – that’s proper groundswell energy. The wind is light and cross-offshore from the SW, which means the wave faces will be clean. The combined energy is strong (1659), so there’s plenty of push. This is a big, powerful swell, and with Guarita being an exposed reef, it’s strictly for advanced surfers. The water temp is around 62°, which is about average for this time of year.
Another one to circle is Wednesday morning, September 16th. It’s a much smaller day, with 3 ft of SSE swell, but the wind is dead calm – glassy conditions. The swell period is a long 12 seconds, so there’ll be smooth, lined-up waves. With that combined energy of 361, it’s a moderate, mellow session. Perfect for a longboard or a fun board if you want a clean, easy paddle.
Then, on Friday morning, September 18th, we get another glassy morning. The swell is 3 ft from the S (12-second period), and with the wind completely calm, it’ll be a mirror. Combined energy is 407 – again, a nice moderate, clean morning.
Now, for the rest of the period, it’s a mixed bag. Saturday the 12th sees a huge 10 ft groundswell from the S, but the wind is a messy cross-shore, making it a choppy, difficult beast. That’s more for the experts or the kamikaze crew. From the 19th onwards, we get a few pulses of 7 ft+ energy from the east, but the wind is consistently onshore or cross-shore, ruining the quality. The crowds at Guarita are sometimes an issue, but on these standout mornings, you’ll likely have a bit of company.
So, to sum it up: the first week is a dud. The real action is the second weekend. Get your skates on for the 13th, or enjoy a quiet glassy session on the 16th or 18th. The long-range stuff for the 20th and 21st looks promising but stay tuned – it’s a ways off.
Rusty.

Information about the Guarita Surf forecast
The above surf forecast table for Guarita provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Guarita can be found by selecting the local surf guide option on the grey menu. Our Guarita 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 (Guarita) 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 Guarita 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.
Guarita is 22 km (14 miles) from Torres. If you plan a holiday in Rio Grande Do Sul, look for hotels and other accommodation in Torres. Torres has rooms for a wide range of budgets as well as car hire and transport links.
