The Lowdown
Right, folks, Rusty here. Let’s have a proper look at what Geriba’s got cookin’ over the next couple of weeks.
First up, the water’s sittin’ at a standard 72°, nothing unusual for this time of year.
The week kicks off on Saturday, the 25th, but don’t get your hopes up for that first session. The morning has a sloppy 4ft S swell (327 combined energy) with a cross wind, so it’s more of a paddle to stay warm than a day to remember. That afternoon and all of Sunday, the 26th, stay pretty ordinary and choppy, with the swell droppin’ off and the wind swingin’ onshore. We’re gonna have a lull here for a few days.
The real spark shows up on Monday morning, the 27th of July. A clean 3ft S swell (339 combined energy) is runnin’ with a nice offshore from the NE. This is a proper session for the beginners and fun-seekers. The afternoon stays clean but drops off a bit.
Tuesday the 28th through to Thursday the 30th are all pretty flat and weak, with swell dropping below 2ft and the combined energy sinkin’ into double digits – not worth wettin’ a wetsuit for.
Friday morning, the 31st July, brings a tiny little glassy moment – 2ft S swell (124 combined energy) with the wind off the water. It’s a cruisy dawny for the longboard if you’re desperate, but it ain’t gonna pump.
The standout window opens on Saturday morning, the 1st of August. We’re lookin’ at a solid 4ft S swell (352 combined energy) with clean offshore winds from the NNE. This is the pick of the early period, no doubt. Geriba handles this kind of S swell beautifully, and with the wind off the land, it’ll be smooth.
Sunday the 2nd keeps it tidy – another 4ft S swell with offshore winds, but the energy starts to fade by the afternoon as that wind cranks up.
The big dog arrives on Wednesday morning, the 5th of August. That’s the session to circle on the calendar. A proper 7ft ESE swell (924 combined energy) is forecast, with a clean offshore NNE breeze. Now, that’s getting into the expert range for sure, too big for beginners, and the break will be heavy. The crowd situation at Geriba can get busy, especially on a morning like that, so get in early. The period is 10 seconds, so it’s not a super long groundswell, but the raw power is undeniable. Thursday the 6th flips the switch, and the swell completely vanishes, droppin’ to a pathetic 0.7ft for the rest of the week and into the next.
So, to sum it up: Saturday the 1st of August morning is your top bet for clean, fun waves that won’t beat you up. Wednesday the 5th of August morning is for the experienced crew who want some size and power, but it’s a proper heavy day. The rest? Mostly flat spells, especially after that big pulse.
Rusty out.

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.
