The Lowdown
G’day, it’s Rusty here. The outlook for Itaúna is a bit of a slow burn, but there’s a couple of windows that’ll get the heart pumping. For the first week, it’s mostly small and ordinary, with a few clean mornings but nothing that’ll get you out of bed in a hurry. Then, around the 27th of July, things start to crank properly, and the second week has some real promise, though it’s a bit of a mixed bag.
Let’s start with Tuesday the 21st of July. It’s a clear morning, with a light NNE cross-off breeze at 9 mph, and the swell is a tiny 3 ft from the east, period of 8 seconds. The combined energy is weak at 82, so it’s surfable but very ordinary. The afternoon gets a little bump in height to 4 ft, but the wind goes cross and the conditions are poor. Water temp is sitting at 72°, which is about average for the time of year.
Wednesday the 22nd is similar – clean in the morning with 3 ft and a cross-off, but the energy is still weak (87). The afternoon goes cross again and is poor. Thursday the 23rd is a write-off – strong onshore winds and tiny swell. Friday the 24th has a clean morning with 2 ft from the SSW and a cross-off, but the energy is only moderate (131). The afternoon jumps to 5 ft from the SSW with a period of 10 seconds and good energy (502), but it’s cross-onshore and choppy, so no good. Saturday the 25th is interesting – the morning is clean with a cross-off and 5 ft from the south, energy at 444, but it’s marginal. Then the afternoon goes glassy, with 5 ft from the south, period of 10 seconds, and a combined energy of 441. That’s a standout for the first week – glassy conditions and a clean 5 ft wave. It’s a point break, so that long period won’t be an issue. However, it’s an advanced spot, so not for beginners, and crowds can be around sometimes.
Sunday the 26th is a letdown – the morning has 3 ft from the south with a 14-second period (very long period), energy at 615, but the wind is cross and it’s marginal. The afternoon is a complete mess with fresh onshore winds. Monday the 27th of July is where it gets good. The morning is clean, with a WNW cross-off at 6 mph, and the swell is 5 ft from the south, period of 12 seconds, and combined energy of 796 – that’s strong energy. This is a clear standout for the week. The waves will have proper shape and power, and with offshore winds, it’ll be a ripper session. The afternoon is smaller and onshore, so get in early.
Tuesday the 28th is clean in the morning but smaller at 3 ft, and the energy drops to 325. The rest of the week is a slow fade into tiny surf and ordinary conditions. There’s a gap from the 29th of July through the 31st where the swell drops to 1 ft to 2 ft, and there’s nothing worth paddling for.
Then the second week kicks in. Saturday the 1st of August, the morning is clean with a 4 ft swell from the southeast, period of 7 seconds, and energy at 301, but it’s short period and a bit weak. Sunday the 2nd of August morning is a standout – clean, with a 6 ft from the east, period of 8 seconds, and combined energy of 931 (strong to very strong). That’s a solid wave, but at 6 ft it’s getting big for beginners, and the short period means it’ll be a bit crumbly. The afternoon has a 3 ft from the south with a 12-second period and energy of 702, but it’s cross-shore and choppy. Monday the 3rd is small again. Tuesday the 4th of August morning is glassy, with a tiny 2 ft from the SSE, period of 13 seconds (long period), and energy of 220. That’s a clean, lined-up point wave but very small. The rest of the second week is a mix of onshore winds and poor conditions, with no real standouts.
So, the best on offer is the morning of the 27th of July at Itaúna – 5 ft, south swell, clean cross-off winds, and strong energy. That’s the one to circle. The second standout is the glassy afternoon of the 25th of July, with 5 ft and clean conditions. For the second week, the morning of the 2nd of August has the biggest swell at 6 ft, but it’s a bit of a gamble with the short period and size – more for the experienced crew.
Signing off, Rusty.

Information about the Itaúna Surf forecast
The above surf forecast table for Itaúna provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Itaúna can be found by selecting the local surf guide option on the grey menu. Our Itaúna 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 (Itaúna) 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 Itaúna 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.
Itauna is 5 km (3 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
