The Lowdown
Alright folks, Rusty here. Let’s have a look at what Geriba’s got cooking for us over the next couple of weeks.
First up, the water temp is sitting at 73°, which is about average for this time of year – no surprises there.
Right now, things are looking pretty flat and sloppy. Monday afternoon has a bit of a bump at 4ft from the east, but it’s short-period windswell at 7 seconds and a cross-off wind is messing it up. Not worth paddling out for.
The first real chance of a wave comes on Tuesday morning, the 4th of August. It’s a small 3ft easterly swell, but we’ve got clean offshore wind from the NE at 19 mph. The period is a bit short at 8 seconds, and the energy is moderate (276), so it’ll be weak but rideable for beginners. It’s a good chance to get some practice in with no crowd.
We see a bit more activity around Wednesday the 5th. The morning has a 3ft south swell with a better 12-second period, and the offshore wind is still solid. It’s still on the small side, but the longer period gives it a bit more shape.
Now, here’s the standout. Hold on for Sunday the 9th of August. We’ve got a 5ft SSW groundswell in the morning with a long 14-second period, and the wind is offshore from the NE at 16 mph. The combined energy is strong (1519). This is the best of the whole window. The waves will have proper power and shape. The afternoon jumps up to 5ft from the same direction with a very long 16-second period, but the wind switches onshore, so get out there early. This one is for the experienced surfers; that size and power will be too much for beginners.
After that, the middle of the week gets messy. Monday the 10th and Tuesday the 11th have similar sized swell (5ft – 5ft), but the wind is cross-on or onshore, and the energy is still strong, but the conditions are choppy. Not great.
We get a second window starting Wednesday the 12th. The swell hangs around 4ft to 6ft from the south, and the wind is cross-off from the east. The energy is high (622 to 873). It’s not as clean as the 9th, but it’s surfable and worth a look if you’re keen.
Things start to fade into the second week. By Friday the 14th, the swell drops to 4ft, but it’s a long-period south swell (14 seconds) and the wind is light. It’ll be clean and small. Saturday the 15th has a 5ft to 5ft south swell, but the wind is cross-shore or onshore, making it choppy.
After that, it’s a long run of poor conditions and small swell through to the end of the outlook. The wind is strong offshore on the 17th and 18th, but the swell is tiny (2ft to 3ft). Not worth the effort.
So, to sum it up: Sunday the 9th of August morning is your absolute best bet. Get on it early for clean, powerful groundswell. If you miss that, the mornings on Wednesday the 12th and Thursday the 13th offer some decent, albeit less perfect, waves.
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.
