The Lowdown
Alright folks, Rusty here. Let’s cut through the noise and look at what’s coming for Geriba over the next couple weeks.
We’ve got a classic late winter scenario unfolding. The first few days are pretty average with some bumpy conditions, so don’t get too excited just yet. It’s not until the 27th that things start to look interesting, and then there’s a real standout shape on the 10th of September that you’ll want to circle on the calendar.
Geriba (Brazil)
This week starts with a bit of a whimper. Wednesday morning the 26th has some head-high, 5 ft south swell rolling in with a long 16-second period, but there’s a cross-shore wind messing it up. The wave energy is powerful though, sitting at 2097, but the surface is choppy. That afternoon, the wind picks up to a stiff 12 mph cross-shore, and the swell jumps to a messy 8 ft – that’s getting into expert-only territory with a cross-chop, and honestly, the kite surfers will be having a better time than us paddle surfers.
Now, Thursday morning the 27th is where we get our first real window. Swell drops a touch to 8 ft from the south, still with a clean 15-second period, and here’s the kicker: the wind comes out of the NE at a gentle 9 mph offshore. That’s the magic word – clean. The energy is still pumping at 2249. This is the standout of the first week. For experienced surfers, this is the session to chase. The water temp is about average for this time of year, so a spring suit will do.
After that, the size fades fast. Friday the 28th drops to 4 ft and the wind gets fresh at 19 mph. By the weekend, we’re down to tiny 2 ft dribblers. There’s a big gap of small, choppy, or onshore junk from the 29th all the way through to the 3rd of September. A few days show some waist-high swell, but the wind is either strong onshore or cross, making it a frustrating paddle.
The second week opens up again on the 4th of September. Friday morning the 4th shows some chest-high 5 ft south swell with a clean 11-second period and a light cross-offshore breeze from the east. The energy is moderate at 478, and the forecast says good conditions. It’s not a giant, but it’s rideable and clean.
Then we hit the real gem. Look at the 10th of September, Thursday morning. The swell builds to a solid 6 ft from the south, with a long 11-second period, and the wind is a clean offshore out of the NNE at 12 mph. The energy jumps to a strong 1242. The conditions are described as excellent for experienced surfers. This is promising but still far out, so keep your fingers crossed, but if it holds, the offshore winds and that solid south groundswell will make Geriba’s banks look very, very good. Crowds are likely here, especially on a clean day like that, so get there early.
That’s the story, folks. A quiet start, a good Thursday morning on the 27th, and a distant but tasty prospect on the 10th of September. Stay patient.
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.
