The Lowdown
Alright, Rusty here, let's have a look at what's cookin' at Geriba over the next couple of weeks.
First off, the water is sitting at a balmy 72°, which is right on the money for this time of year, so no surprises there.
The week kicks off with a solid pulse of energy. Thursday the 27th morning is where it's at – we've got a nice 8ft SSE groundswell with a long 15-second period rolling in. That's a lot of water moving, putting the combined energy at a hefty 2817, so it's got some serious grunt. For the experienced crew, this is the standout window. The wind is a light, cross-off breeze from the east, keeping things reasonably clean despite the size. The afternoon holds similar size at 8ft, but the rain and a bit more wind make it less appealing.
Friday the 28th is a step down. The swell drops to 4ft in the morning and the wind picks up, making conditions just ordinary. Not worth rushing for.
The weekend is a write-off. From Saturday the 29th right through to Tuesday the 1st of September, the swell is tiny and the wind is howling. We're looking at a solid four-day stretch of nothing surfable. Wednesday the 2nd shows a brief uptick of 5ft on the afternoon, but it's with onshore wind and a poor outlook. Not one to get excited about.
There's a glimmer of hope towards the end of the week. Thursday the 3rd afternoon gives us a 6ft SSE swell at 11 seconds, with a cross-shore breeze that might clean it up a touch (energy at 669 – moderate). It's marginal, but a beach-and-reef setup like this with onshore wind could actually be more interesting for a kite session.
Friday the 4th morning is the next real bright spot. We get a 6ft S groundswell with a 12-second period (energy at 965) and a stiff 19 mph offshore wind from the northeast. That's fresh and clean. The size is solid, but with that offshore wind, the waves will be holding up nicely. It'll be a bit of a battle to get out, but the reward is there for those who make it.
After that, it trails off into smaller, cleaner but weak surf from the 6th to the 11th. The 6th and 7th of September have some glassy mornings and light offshores with knee-to-waist high waves, but it's nothing to write home about. The long period (16 seconds) on the morning of the 7th will produce some very clean but slow lines at Geriba – it might be a bit too straight for the beach break, but the calm conditions will be a treat for a log.
All in all, the standout is undeniably Thursday the 27th morning for the experienced crew throwing themselves into that 8ft SSE groundswell. For the regular punter, Friday the 4th morning offers the best balance of clean offshore wind and rideable size.
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.
