The Lowdown
Alright, let’s get this straight. The next couple of days are going to be a bit of a tease, but if you’re patient, there’s some real magic on the horizon.
Right now, through Thursday the 7th, it’s pretty gutless out there. We’ve got some small swell in the water, but the winds are messing with it. Mornings are looking a little cleaner with a light offshore, but the swell is just too small and weak to get excited about. The energy is weak, and you’d be scratching for ankle-biters. The period is short, so it’s not packing any punch. It’s a good time to do the chores, not the surf.
Then we get a little hiccup on Saturday afternoon. South swell bumps up to 4ft, but the period is a weak 6 seconds and the energy jumps to 634. That’s junky, onshore slop. Not worth the paddle out.
But hold on. Sunday morning, August 9th, is where it starts to get interesting. We’ve got a solid 5ft of south swell rolling in with a 14-second period. The energy is pumping at 1077. That’s a proper groundswell. The wind is offshore from the NE, which means it should be glassy and clean. This is the standout of the first week. Geriba (Rio de Janeiro) is going to have some proper lines. This is the one to circle on the calendar. The water temp is 73°F, which is about average for this time of year, so a steamer is optional.
The rest of that week is a bit of a mixed bag. The swell hangs around but the wind gets messy, turning cross-onshore and chopping it up. There’s some size, but it’s not going to be pretty. The energy dips and spikes, but the quality just isn’t there. Monday and Tuesday look particularly rough.
We get a bit of a reprieve on Wednesday afternoon, August 12th. The wind goes light and cross-offshore, and the swell cleans up to 3ft with a 13-second period. It’s not huge, but it will be fun and user-friendly. The energy is 662, so there’s some push behind it.
The following weekend, the 15th and 16th, looks like it could be the real deal. The swell is building, and by Sunday the 16th we’re looking at a solid 7ft of south swell with a 13-second period. That’s a lot of water moving. The energy is massive, hitting 1538. That’s strong to very strong. The wind is cross-offshore from the NE, but it’s blowing 25 mph, which is a proper breeze. It will be big, powerful, and challenging. This is for experienced surfers only. If you’re a beginner, stay well clear. This is a hold onto your trunks and hope for the best kind of day.
The last couple of days of the forecast, on the 18th and 19th, look promising again. The swell eases slightly, but the wind goes light and the period stays long. The 19th looks particularly clean, with a light offshore and a 14-second south swell. It won’t be as big, but it might be the best quality of the whole run.
So, if you’re looking for the best of it, Sunday morning the 9th is your call for the first week. For the second week, keep an eye on the 19th. It’s a long way out, so treat that one with a bit of caution, but it has all the ingredients.
There’s a lot of surf on the way, but it’s not all going to be good. The big stuff is going to be challenging, and the small stuff is going to be frustrating. Patience is key.

Information about the Geriba Surf forecast
The above surf forecast table for Geriba provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Geriba can be found by selecting the local surf guide option on the grey menu. Our Geriba 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 (Geriba) 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 Geriba 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.
Geriba is 5 km (3 miles) from the city of Armacao de Buzios. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Armacao de Buzios. Armacao de Buzios has rooms for a wide range of budgets as well as car hire and transport links.
