The Lowdown
Alright, this is Rusty, and I’m looking at the forecast for Itaúna for the next couple of weeks.
We’ve got a bit of a slow start, but there’s some real potential brewing later on. The first few days are pretty gutless, with tiny swell and messy wind. The water temp is sitting about average for this time of year at 73°, so nothing wild there.
The first real flicker of life comes on Wednesday morning, August 5th. It’s not huge, with a 3ft south swell, but a light NE breeze is blowing cross-offshore, keeping things clean. The combined energy is moderate (370), so it’s a good session for the advanced crew who know the point. Crowds are possible here, so get in early.
The next couple of days are a write-off – small, weak, and choppy. Then things get interesting. From Saturday, August 8th, the ocean starts to growl. The swell builds quickly, hitting 6ft by the afternoon, but it’s a messy SSW windswell with a short period. The real energy kicks in Sunday, with a 7ft SSW swell and a long 14-second period. That’s a proper groundswell, and combined energy is way up (1611). This is big, powerful stuff for experts only. The wind is light and cross-shore in the morning, but it’s still a bit lumpy.
The standout window is looking like Thursday, August 13th. The morning session is the one to circle. We’ve got a 4ft SSW swell, a solid 13-second period, and a clean NE cross-offshore breeze. The energy is moderate (773), and the forecast says “expect very good surf conditions.” This is clean, lined-up, and perfect for the point. It’s about as good as it gets for this run.
The following week holds more promise but is less certain. Monday, August 17th morning has a 5ft S swell with a clean cross-offshore breeze again – another solid option. And then Wednesday, August 19th morning looks magic: a 4ft SSE swell with a very long 14-second period and glassy, near-calm wind. The point will be handling that long-period energy beautifully, offering some real gems.
Overall, it’s a slow start, but the second week has some proper sessions. The standout is Thursday, August 13th morning, with a close second being Wednesday, August 19th morning. Don’t sleep on those.
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.
