The Lowdown
Alright, Rusty here. Let’s break it down.
First few days are a dud. Small, weak, short-period east windswell with the wind all over the place. Not worth paddling out.
Things perk up on Saturday, July 25th. A 5-foot south swell shows up in the morning with light offshore winds from the north-northeast. The water’s about 72°F, normal for this time of year. Clean, moderate energy – that’s the first real green light.
The big one is Saturday, August 1st. Smooth, glassy conditions early. A solid 7-foot south groundswell with a long 13-second period. The energy is massive. This is for advanced surfers only. The point at Itaúna will hold it, but that size and long period means it’s going to be powerful.
Before that, Monday, July 27th morning has a 4-foot south swell with light cross-off wind, clean. Then Sunday, August 2nd morning gives another clean 5-foot south swell.
There are some flat, ordinary days in between, especially late July, but that August 1st window is the one to plan for.
Crowds can show up when it’s good at Itaúna.
Keep the faith, the real swell is coming.
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.
