The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming our way.
We’ve got a solid run of surf on the cards, but it’s a tale of two halves. The first few days are for the experienced crew only, with some serious size and energy. Then things back right off, and we’re looking at a long, quiet patch before a possible pulse of new swell moves in around the start of September.
The standout window is Wednesday morning, the 26th of August, at Itaúna. It’s a world-class point break, and conditions are set to be pristine. We’re looking at a 7ft swell from the south, with a long period of 12 seconds. The wind is dead calm, glassy as can be. The combined energy is strong (2111), so there’s plenty of grunt behind those waves. This is a session for the experienced surfer – it’s not a beginner wave at this size. The water temp is sitting at 73°, which is pretty much bang on average for the time of year, so no surprises there.
The build-up to that comes on Tuesday the 25th of August. The morning sees an 8ft south swell, 14-second period, with a cross-shore breeze. The wave energy is very strong (2698), but it’s a bit messy with a cross-chop, so it’s a bit of a war zone out there. The afternoon is much the same but with light rain, so not our best bet.
After that Wednesday morning glass-off, the wind turns on us Wednesday afternoon. The swell jumps to 8ft from the south with a long 15-second period, and the energy is massive (3148), but a moderate cross-onshore breeze is going to chop it up. Not the one.
Thursday morning the 27th offers another chance for a surf. The swell drops to 8ft from the south, 14-second period, and the wind is glassy from the west. It’s a clean, powerful wave, but still very much for the advanced crew. The energy is still strong (2186). Thursday afternoon sees the wind swing back to a cross-shore, and the quality drops.
From Friday the 28th onwards, the swell drops off a cliff. The south swell fades, and we switch to a weak, short-period easterly windswell. The energy readings drop into the hundreds (544, 430, 196...), and the waves are tiny, around 3ft or less. There’s a long stretch of poor to ordinary conditions that runs right through the end of August and into the first few days of September. It’s a real flat spell, with nothing worth paddling out for.
Then, on the 3rd of September (Thursday), we see a new solid south-southeast groundswell pushing in. The morning looks clean with a cross-offshore breeze, a 7ft swell, and an 11-second period. The energy is good (966). This is a promising, long-range prospect, but it’s a week and a half away, so keep an eye on it. The following days look smaller but still with some clean windows on offer.
So, to sum it up: get on the Wednesday the 26th or Thursday the 27th of August if you’re an experienced surfer. The rest of the month is a write-off for a paddle, but kite surfers might find some fun in the breezy, small conditions. The long-range stuff around the 3rd of September is worth watching.
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.
