The Lowdown
G’day, it’s Rusty. We’ve got a slow couple of weeks ahead, but there’s a couple of windows worth chasing. Water’s at 73°F, which is normal for this time of year, so the wetsuit stays the same. The wave energy is mostly moderate through the first week, but it does get properly strong mid-period before dropping off again.
First real session is Wednesday morning on the 9th. It’s small at around 3ft, but it’s glassy with a bit of offshore wind. That’s your clean window. Energy is moderate at 340, so not a flogger, but the lack of wind will keep it tidy. Thursday the 10th morning is similar—3ft of south swell, 12-second period, light offshore cross-off wind. Energy bumps to 515, and it looks clean and lined up.
The standout, though, is Friday morning on the 11th. Swell pushes to 4ft from the south, the period stretches to 14 seconds, and there’s basically no wind. Energy reads 742—that’s the kind of push that makes Itaúna (Big Island) proper. Glassy, long-period groundswell, and as a point break, it’ll handle that longer period well. Just expect longer waits between sets, but the shape will be worth it.
Saturday the 12th morning drops to 2ft, energy tanks to 214. There’s a storm chance, but light offshore wind might make it a fun grovel if you’re keen.
Then Sunday the 13th gets heavy: 6ft in the morning, 8ft in the afternoon, with energy roaring up to 1080 and then 1339. That’s strong, powerful stuff. But the wind is cross-onshore and choppy. Messy. Honestly, that setup looks way more interesting if you’ve got a kite than a paddle board.
Monday the 14th still has size around 4ft to 5ft, but the wind is a moderate cross-off. It’s clean, but quality is down a notch. Energy is still up around 754, yet the period drops to 10 or 11 seconds. Rideable, but not the Friday kind of clean.
From Tuesday the 15th through the end of the first week, it’s mostly 3ft to 4ft, with afternoon onshores killing a lot of the vibe. The second week starts to lose its punch. Wednesday the 16th has some size at 6ft, but the period is down and winds are cross. Not your friend.
The next real nod is Thursday the 17th morning—5ft of south swell at 12 seconds, light offshore east-northeast wind, energy at 669. Clean and should offer proper point-break shape. That’s your backup to Friday the 11th.
After that, wave heights hold around 3ft to 4ft, but winds get messier. Friday the 18th is too windy at 25 km/h—offshore, but energy drops. The weekend of the 19th and 20th sees a shift to easterly swells with short periods, which aren’t ideal for the point. Saturday the 19th morning has a brief look with 3ft and a 12-second south swell, light offshore wind, but that’s about it.
The final stretch from Monday the 21st to Wednesday the 23rd is mostly small and shabby. Monday is 3ft to 5ft from the east with short periods and moderate wind. Tuesday the 22nd morning is glassy but only 4ft from the southwest at a poor 6 seconds. Energy is weak at 146. Wednesday has some period but it’s cross-onshore and fading.
So the call is simple: if you get one session this fortnight, make it Friday the 11th in the morning. Thursday the 17th morning is the backup, but the long-range promise fades and the second week is far less certain. Keep an eye on the dawn reports.
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.
