The Lowdown

Alright, let's get into it. So, we're looking at Geriba for the next couple of weeks, and honestly, it's a bit of a mixed bag. The first few days are pretty ordinary, with small, weak swell and onshore winds making a mess of things. We've got a long stretch where it's just not worth paddling out.

Friday the 28th is a write-off. We're looking at 4ft of south swell with a 12-second period, but that cross-offshore wind from the ENE at 12 mph just chops it all up. The energy reading is 610, which is moderate, but the conditions are marginal at best.

Saturday the 29th morning could be a sneaky little session if you're desperate. The swell drops right off to 4ft from the east, but the wind is offshore from the NE at 16 mph. It’s a short-period 7-second swell, so it'll be a bit crumbly and weak on the beach. That energy is down to 345.

Then we hit a proper dead zone. From Saturday afternoon all the way through to Tuesday the 2nd of September, the swell just flatlines. We're talking 2ft and below, with onshore winds. It’s a total desert out there.

Wednesday the 2nd is where things start to get interesting, but not for the faint-hearted. The morning shows a building swell of 3ft from the SSW, but it's onshore and messy. The afternoon is a different beast—a solid 8ft of SSW groundswell at 12 seconds rolls in, pumping out 1413 for energy. That is a lot of power, and it's going to be a big, heavy, onshore mess. This is strictly for experienced surfers on a reef or point setup if you can find a bank that works, but Geriba itself as a beachie will be a washing machine. Kite surfers might have a field day, but for a paddle surfer, this is a pass.

Thursday the 3rd sees the swell settle a bit, with 6ft from the south in the morning, but it's still onshore. Not great.

Finally, we get a window. Friday the 4th of September morning. This is the standout of the whole outlook. We've got a clean 5ft of south swell with a 10-second period, and the wind goes glassy—zero, from the SW. The energy is still solid at 580. This will be the cleanest, most fun surf of the fortnight at Geriba. The water is 72°, which is spot on average for this time of year, so no surprises there. This is the one to circle.

After that, the wind gets messy again. Saturday the 5th and Sunday the 6th have small swell and howling offshore winds. There's a brief moment on Sunday afternoon with 2ft and a 14-second period, but the wind is offshore and it’s tiny. Not worth the paddle.

From Monday the 7th onward, we go back into a slump of small, onshore, weak surf until Wednesday the 9th, where we might get a glassy 3ft morning again. Then Thursday the 10th and Friday the 11th show some modest 4ft and 3ft swell with offshore winds, but it's all raw energy and the wind is strong. The Saturday the 12th finishes the period with 4ft to 4ft of short-period south swell and a fresh offshore breeze, but again, it's not going to be pretty.

So, the big takeaway: surf is quiet for the first half, then there's a monster swell mid-week for experts only, and your one true shot at a clean, fun session is Friday the 4th of September morning. Get on it.

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.
