The Lowdown
G’day, this is Rusty. We’ve got a solid run of surf coming up at Guarita (reef) , kicking off Monday morning and stretching through that first week, with a real standout window shaping up for Thursday the 13th. The energy is strong across the board early on, but there’s a definite drop after that first weekend, so you’ll want to make the most of the first few days.
Monday morning the 10th sees a solid 6.2 ft S swell, period at 12 seconds, and the combined energy is pumping at 1729 – that’s strong to very strong. Winds are cross-offshore, so it’s clean, but conditions are described as marginal with questionable tides, so it’s not gonna be perfect. Worth a look, but keep an eye on the tide. Monday afternoon gets messier with cross-shore wind and energy dropping to 951, so morning is the go.
Tuesday morning the 11th is where things clean up nicely – 5.6 ft SSE swell, 12 seconds, light north offshore breeze, and 890 combined energy. This is clean and surfable. Afternoon gets a little cross-shore again, but it’s still okay. Wednesday morning the 12th keeps the same vibe with 5.2 ft SSE swell and light offshore – good waves, light rain about but the surface stays clean.
Now, Thursday the 13th is the standout. Morning pushes 5.6 ft SSE swell, period bumping to 14 seconds, combined energy jumps to 1140 – that’s strong. Winds are light cross-offshore, clean, and conditions are rated excellent for experienced surfers. This is groundswell, and at a reef break that’s a treat – long period energy, well-shaped waves, and easier paddling between sets. Afternoon gets glassy, with 5.6 ft and 13-second period at 1015 energy – just magic. This is the pick of the whole outlook. Guarita (reef) handles south and south-southeast swells well, and these directions are spot-on.
Friday the 14th backs off a bit with 4.6 ft but still 14-second period and clean morning – good waves, just not as punchy. Afternoon gets cross-onshore, so morning’s the go. Saturday the 15th drops further – 3.3 ft morning, 2.6 ft afternoon with glassy conditions – small but clean, worth a paddle if you just want to cruise.
From Sunday the 16th onward, things get small. Sunday morning is 2.3 ft with poor conditions, and through the next week it mostly stays under 3.9 ft. There’s a brief bump on Tuesday morning the 18th with 3.9 ft and clean cross-off wind, but it’s short-period at 7 seconds, so not much grunt. The week after that, from the 19th to the 25th, is mostly small, choppy, or poor – not worth getting excited about. A little glassy window on Thursday afternoon the 20th with 3.3 ft and 12-second period could give you a fun little session, but it’s nothing to write home about.
Summing it up: hit Tuesday morning the 11th for clean, easy waves, but Thursday the 13th is your top day – good size, long period, glassy afternoon, and the reef will be working beautifully. After that, the juice is gone for a while. This is Guarita (reef) at its best when the swell and wind line up. Stay keen for that Thursday.

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.
