The Lowdown
Alright, surfers, Rusty here. Let's look at what's on the menu for the Geriba (Brazil) region.
We’ve got a bit of a slow start, but the back half of this forecast period is shaping up to be a cracker. The water temp is sitting right around average for this time of year, so no surprises there.
The first few days are a write-off for me. Friday the 21st and Saturday the 22nd are a total bust with tiny, weak swell and poor conditions. You’ll be scratching your head, not your board. There’s a bit of a gap here with no real surf on offer. Sunday the 23rd sees a small bump in energy, but it’s still marginal at best.
Things start to get interesting from Monday the 24th as a solid S-SSW groundswell starts to build. The energy jumps up significantly, but it’s paired with onshore winds and rain, making for a choppy mess. Not worth the paddle.
Now, hold onto your leashes, because the real standout is Wednesday the 26th. The morning session is the pick of the entire forecast. We’ve got a solid 8 ft groundswell from the S with a very long period of 16 seconds, packing a massive punch in terms of energy (4172). The wind is a gentle cross-offshore breeze from the ENE, keeping the waves clean. This is a setup for experienced surfers only – that size and power will be a handful for beginners. The long period will mean long, clean lines and plenty of power, but it might make the waves a bit too walled at a beach break like Geriba.
Tuesday the 25th is also decent, with similar swell size and clean cross-off winds, but the energy is a touch lower and the period is a bit shorter. Thursday the 27th still has some size, but the wind is howling, making it a tricky session.
After that, the swells start to fade out through the end of August and into the first week of September. The first few days of September bring a new, weaker, and messy W-SW windswell, but it’s not worth getting excited about.
So, if you’re an experienced surfer, block out the morning of Wednesday the 26th. It’s the clear winner. For everyone else, keep an eye on the forecasts, because conditions can change.
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.
