The Lowdown
Alright folks, Rusty here, gettin' you the lowdown on what's cookin' for the next couple of weeks. We're lockin' onto one spot, so let's ride.
Okay, so we're startin' off a bit rough. The first few days are lookin' a bit average, but there's light at the end of the tunnel. We've got a decent pulse of energy rollin' in, but the wind's gonna be a bit of a fluffer to start with.
Geriba is our only play this period. It's a beginner-friendly spot, which is good for the size we're gettin', and it's generally consistent.
The first real window of opportunity kicks off on Wednesday, the 12th. On Wednesday morning, we're seein' a solid 7ft swell out of the south, with a 12-second period. The combined swell energy is a healthy 1161, and we've got a light breeze swingin' cross-offshore. That's gonna keep things clean and fun. This is a top pick for the experienced surfers out there.
Then Thursday the 13th, the morning session is another standout. Still a solid 6ft of S'ly swell at 13 seconds, energy at 1124, but the big news is the wind—it's gonna be a clean, direct offshore from the NNE. That'll groom the waves beautifully. Again, this is an excellent setup for those who know what they're doin'.
Friday the 14th morning holds promise too. Another 6ft of S swell, 14-second period, and light offshore winds from the NE. It's clean, it's got energy (1303), and it's prime time for the experienced crew.
Water temps are about average for this time of year at Geriba.
Now, after that initial run, things kinda fade out and get a bit sloppy for a stretch. We hit a flat patch from around Monday the 18th all the way through to Friday the 22nd. There's a bit of a pulse comin' back on the 22nd, but it's nothin' special.
The real wildcard, and the one that's got me a little excited, is lookin' way down the line. On Tuesday the 25th, we've got a bomb swell headed our way. We're lookin' at 4ft of south swell, but the period is a massive 17 seconds—that's a proper groundswell. The combined swell energy is a powerful 986. But the absolute killer is the wind: it's glassy. Total flat calm. That early morning session could be absolutely magic for the experienced guys, if the tide plays ball. The longer period will make for some proper grunty lines, but it might get a bit straight on a beach break; these long-period swells are better when they have a point or a reef to bend around, but with glassy conditions, any wave will be a gem. It's a week and a half away though, so chalk that one up as a very promising long-range possibility.
So, the short story? Snag the Wednesday 12th, Thursday 13th, and Friday 14th mornings for the best guaranteed fun. Keep an eye on the 25th for a potential dream session if the forecast holds.
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.
