The Lowdown
Alright, Rusty here, let’s have a look at what Geriba (Brazil) has in store for us over the next couple of weeks.
First up, we’ve got a solid pulse of swell rolling in from the south, but it comes with a fair bit of wind early on. Monday the 24th is looking average at best – we’ve got a bumpy 7ft south swell with a moderate cross-onshore breeze making things choppy. The combined energy is strong (1487), but the surface is messy. Monday afternoon picks up to 8ft (2677 energy), but it’s still cross-onshore and choppy. Not a day to get too excited about.
Tuesday the 25th cleans up nicely though. The wind swings cross-offshore from the east, and we’ve got a 8ft south swell (2128 energy) in the morning. The 14-second period means good shape, but this is still a fair size – solid for intermediate to experienced surfers. Tuesday afternoon holds at 7ft (1553 energy) and stays clean. This is a good window.
Now, Wednesday the 26th – this is the standout of this forecast period. Early morning we get a glassy 5ft southeast groundswell with a very long 16-second period (1985 energy). That’s the sort of clean, lined-up surf that makes Geriba a pleasure. Perfect for experienced surfers, but the long period will make it a bit tricky at the beach – expect long waits between sets and waves that stand up nicely.
The rest of the week and into early next month sees a steady decline. Thursday the 27th has a 7ft south swell with strong offshore wind in the morning, but the wind is howling at 25 mph, making it hard to paddle into. The afternoon is a lot better – 7ft and gentle offshore breeze (1761 energy) – clean and workable. Friday the 28th drops off to 4ft and 3ft with light energy (470 and 349). Saturday and Sunday the 29th and 30th are tiny – 2ft and below, with fresh offshore winds but hardly any swell to work with.
We hit a real lull from the 31st right through to September 1st – flat, poor conditions, less than 0.3ft and messy wind. Then a little bump on September 2nd: a 5ft southwest swell (290 energy) with glassy conditions in the morning. Clean, but small. That lasts into the 3rd and 4th with cross-offshore winds and similar 4-4ft south swells – marginal but rideable. By September 5th the wind picks up again, and from the 6th onward it’s dropping off into the doldrums.
So, if you’re looking for the best, get out on Wednesday morning the 26th – glassy 5ft south-southeast swell with that long 16-second period. Clean, punchy, and just a few guys out if you’re lucky. Beautiful session. The Tuesday the 25th is a solid backup.
Overall, a decent first week, then a long quiet stretch through the end of August into early September. It tends not to stay poor forever here, but this run looks pretty flat for a while.

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.
