The Lowdown
G’day, Rusty here. Let’s break down what Praia Brava’s got lined up in the next couple of weeks.
Right out of the gate, Monday the 7th is dead flat with tiny 1ft waves and no energy — don’t even bother. Water temp’s about 73°, pretty average for this time of year.
Tuesday the 8th wakes up with a 5ft south swell, combined energy moderate at 861, period 10 seconds, but the wind’s blowing cross at 16 mph, so it’s lumpy. Not a cracker, but it’s the first real size. Wednesday the 9th afternoon turns glassy with 5ft from the ENE, short 7-second period, combined energy of 468 — clean and surfable, a decent little window.
Thursday the 10th morning offers a long-period 4ft south swell at 12 seconds, clean offshore flow, and 725 combined energy. That’s a groomed option for the experienced crew.
The true standout is Monday the 21st morning. We see a solid 7ft ENE swell, glassy calm winds, and strong combined energy at 630. Water’s still seasonal. That’s going to be clean and powerful — a bit much for beginners, but for anyone with some chops, it’s the pick of the forecast.
Saturday the 19th afternoon kicks up a big 8ft south swell with a very long 14-second period and massive combined energy of 2014, but the wind’s a messy cross at 22 mph. That’s more of a kite-surf day than a smooth paddle session.
There’s a long dry spell from the 12th through the 20th, mostly marginal or poor. Stick with Monday the 21st morning — that’s your best shot.
Rusty.

Information about the Praia Brava Surf forecast
The above surf forecast table for Praia Brava provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Praia Brava can be found by selecting the local surf guide option on the grey menu. Our Praia Brava 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 (Praia Brava) 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 Praia Brava 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.
Praia Brava is 3 km (2 miles) from Cabo Frio. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Cabo Frio. Cabo Frio has rooms for a wide range of budgets as well as car hire and transport links.
