The Lowdown
Righto, let’s have a look at what’s on offer at Guarita over the next couple of weeks.
The outlook kicks off with a bit of a slow start. Sunday the 6th is a write-off – messy, cross-shore wind and a choppy 7ft south swell that’s just not clean. The wave energy is moderate though, sitting at 767. Water temp is 62°, which is about average for this time of year, so nothing unusual there.
The first real standout comes Monday morning, 7th September. Glassy conditions, a 5ft south-southeast swell at a solid 10-second period, and the combined energy is a moderate 388. This is the pick of the early window – clean, workable, and with that offshore wind, it’ll be worth the paddle out. The wind is light from the north, so you’ll be looking at some nice, lined-up waves on this exposed reef break. It’s an advanced spot, so not for the groms.
Tuesday morning the 8th drops off a bit to 3ft, but Tuesday afternoon glass-off again with that same 3ft south-southeast swell, period still 9 seconds, and energy at 257. It’s small but clean, and if you’ve got a log, you’ll have fun.
Wednesday morning the 9th shows a 3ft swell but with a long 12-second period – that’s proper groundswell energy, and the combined energy is 327. It’s a cross-off wind, so clean. The long period might make it a bit straight at a beach break, but for a reef like Guarita, that’s a good thing. Worth a look.
The middle of the week gets a bit ordinary. Thursday and Friday are marginal at best, with small swell and deteriorating winds. Friday afternoon the 11th is a write-off with 12 mph cross-on wind and a weak 4ft easterly swell. Energy drops to 249.
Saturday the 12th morning is clean but tiny at 3ft, and then the wind howls in the afternoon from the southwest at 22 mph, with a 6ft south swell. That’s a clean cross-off, but it’s more for the experienced crew – the energy jumps to 769. That’s a solid pulse, but with the wind, it’s a tricky one.
Sunday the 13th has a 7ft south-east swell, energy at 705, but it’s cross-on and choppy. Not great. Monday the 14th has a similar size in the 5-6ft range, but with moderate cross-shore wind and chop. Not one to get excited about.
The second week gets a bit more interesting. Thursday the 17th morning has a 5ft south swell with an 11-second period, energy at 593, and light cross-shore wind. It’s marginal, but the period is decent. Then Saturday the 19th afternoon sees a surge in energy to 1062 – that’s strong wave energy from a 4ft south-southeast swell with a very long 16-second period. The wind is cross-on, so it’s a bit bumpy, but that groundswell pulse is proper. Good for a reef, less so for a beach.
The real standout, though, is Sunday morning the 20th September. A 6ft east-northeast swell, period 7 seconds, but the wind is glassy light from the west-southwest, giving you clean conditions. Combined energy is 644. This is the best wave of the run – punchy, clean, and the reef will handle the shorter period. Crowds are possible here, so get in early.
Monday the 21st drops off to 5ft and clean, but with moderate wind, it’s okay but not a standout.
So, overall, the best windows are Monday morning 7th September and Sunday morning 20th September. The 20th is the bigger, cleaner standout, but it’s a week and a half away, so keep an eye on it. The rest of the period is a mix of small and messy, with a few clean but tiny windows in between.

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.
