The Lowdown
Alright, Rusty here. Let's have a look at what's on the menu for Geriba over the next couple of weeks.
Honestly, mate, it's a pretty grim stretch for the most part. We're looking at a long, flat spell to kick things off, with nothing worth paddling out for from Tuesday the 28th of July right through until the end of the first week of August. The swell is tiny, mostly around 1 ft to 2 ft, and while the wind is often offshore or cross-offshore, the waves just don't have any push. The combined wave energy is weak, sitting between 33 and 274 (moderate energy at best), and the forecasters are calling it "poor surf conditions" day after day. There's a bit of a bump on Friday the 31st of July with a 4 ft SSE swell and a 9-second period, but the wind is cross-shore and messy, so it's not one to get excited about. The whole first week is a write-off.
Then, after a solid ten days of nothing, we finally get a cracker. The standout is on Tuesday the 11th of August. The early morning session is looking like the best on offer by a long shot. We’ve got a clean 5 ft swell from the south with a very long 15-second period—that's proper groundswell energy. The combined energy is a massive 1172, which is strong. The wind is glassy, dead calm, which is a major positive. The water temp is sitting at 72°, which is about average for this time of year. This is a good one for experienced surfers, as the swell is over 5 ft, and that long period will make for some powerful, lined-up waves. Keep in mind at a beach break like Geriba, a long-period south swell can sometimes break a bit too straight, but with those conditions, it’s going to be clean. The crowd factor is often, so expect a few others out there, but for the quality on offer, it's worth it.
The following Wednesday morning, the 12th of August, holds a similar size and energy, with a 5 ft south swell and a 15-second period, and the energy is even higher at 1231. However, the wind is a light cross-onshore, which will put a bit of a wrinkle on the face. It's still a solid day for the experienced crew, but the Tuesday morning is the real winner.
So, to sum it up: a long, flat, boring first week, then a proper window of quality south groundswell for the second week. The clear winner is Tuesday morning, the 11th of August. Don't sleep on it.
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.
