The Lowdown
Alright, Rusty here. Let’s talk about what’s coming up at Geriba.
The next 16 days are a bit of a mixed bag, with a long flat spell at the start. We're not seeing anything worth paddling out for until Saturday morning, August 1st. But even then, it’s not a classic. There’s a run of flat or poor conditions from the 31st of July right through the first week of August. For about a week, you’ll be looking at clean-looking water but waves that are just too small or weak to get excited about. The combined swell energy is mostly in the weak to moderate range, barely cracking 100 (205) on the 31st, then dropping to low numbers like 73, 31, 48... not enough to push you around.
The real standout action doesn’t arrive until Sunday, August 9th, in the afternoon. That’s when the ocean wakes up. A solid south swell rolls in at 6ft, with a period of 16 seconds – that’s proper groundswell, long period and full of energy. The combined energy jumps to 1469, a strong reading. The wind is cross-off from the ENE, keeping the surface clean. This is a serious session for intermediate and experienced surfers – the long period will make Geriba, an exposed beach break, a bit tricky because those long-period swells tend to throw down fast and close out, but the power is there. For beginners, 6ft is starting to get out of their comfort zone.
Then Monday morning, August 10th, it gets even bigger, with 8ft from the south. That’s expert territory. The combined energy hits 3043, which is very strong. But the wind shifts cross-on from the WSW, and with that much size and onshore texture, it’s going to be a messy, choppy beast. The setup looks more interesting for kite surfing than paddle surfing.
The best combination of size, wind, and quality looks like Wednesday morning, August 12th. The swell drops to a more manageable 4ft from the south, period at 13 seconds. The wind is offshore from the NE, light and clean – that’s a major positive. Combined energy is a solid 538, moderate but punchy. This is the one to circle. It’s not too big, it’s offshore, and it’s clean. The crowds at Geriba are often there, so expect company, but the quality will be worth it.
Water temperature is sitting at 73°F, which is only 0.4°F warmer than average for this time of year, so nothing unusual – just your standard warm water for a winter session.
So, to sum it up: the first week is a write-off. The second week has a couple of windows, but the Wednesday morning, August 12th is your best bet for a clean, fun session. The Sunday afternoon, August 9th is for the bigger-wave crew, but expect some lumpy conditions.
Rusty.

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.
