The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
First up, we’ve got a bit of a dry spell to kick things off. Looking at the charts, the first proper surf worth paddling out for doesn’t show up until Monday morning, July 27th. That’s a few days of flat or junk conditions to get through, so be patient.
Monday morning, July 27th, at Geriba is where it’s at. The combo is looking sweet: a clean 3ft swell from the S, with a 12-second period pushing some decent energy (348). The wind is a light offshore from the NNE, and the water’s sitting at a comfortable 72°, which is pretty much bang on average for this time of year. The whole place is exposed to the swell and the direction is lining up nicely with what works best. Beginners will be stoked – it’s not too big, and it’s consistent. Just keep an eye out for crowds, they can be a thing here often.
Monday afternoon, the wind swings more cross-offshore and the swell drops a touch to 3ft. It’s still clean, but the energy drops off (236) and it’s more marginal. That Monday morning window is the real gem.
After that, it’s a long stretch of ordinary. Tuesday the 28th through to the end of the first week of August is mostly poor. The wind is howling from the NE at 18-25 mph, blowing everything out. The swell is tiny, mostly under 2ft, and the energy readings are weak (down to 19). You’ll see a few moments of “surfable but very ordinary” on Wednesday the 29th morning and again on Wednesday, August 5th morning, but with only 2ft on offer and moderate offshore winds, it’s not worth getting too excited about. The ocean is just not cooperating.
Now, hold onto your board, because the real standout is a long way off. Saturday, August 8th morning is looking like the one to circle on the calendar. Geriba is expecting a bump in swell to 5ft from the S, with a very long 14-second period. That’s some serious groundswell energy (799!). The wind is glassy – literally glassy, with a slight air from the SSE. That’s about as clean as it gets. The swell is a bit over 4ft, so it’s a step up for the beginners, but for the crew that knows what they’re doing, this is going to be the best session of the whole forecast. The only caveat is that with a long period like 14 seconds, it can break a bit straight at a beach break, but in these conditions, expect some proper lines.
The afternoon of the 8th drops to 4ft, but the wind picks up a little and it gets more marginal. Hit the morning session hard.
After that, we’re back into a slump. The second week is mostly small, weak, and blown out by strong NE winds. There’s a tiny window on Sunday, August 9th morning with 3ft and a light offshore, but it’s just ordinary. Nothing to write home about until the next swell comes through.
So, to sum it up: the best bet is the glassy Saturday morning, August 8th. Monday morning, July 27th, is a solid backup. The rest of the 16 days is mostly a write-off, so pick your moments wisely.
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.
