The Lowdown

Alright mates, Rusty here. Let’s have a look at what’s coming our way.

We’ve got a bit of a slow start, but there’s a nice run of solid, clean swell for the experienced crew from the 12th through the 15th. After that, things go quiet for a stretch, with a long gap of almost a week where there’s nothing worth paddling out for. The surf does try to make a comeback later, but it’s a bit of a mixed bag.

Kicking off on Wednesday, August 12th, Geriba is the spot to be. The morning serves up a solid 7ft south swell with a 12-second period, and the combined energy is pumping at 1161. Winds are light and cross-offshore, keeping things clean. This is proper groundswell, so you’ll get good lines, but the size is over 7ft, so this is one for the experienced guys only. The water temp is about average for this time of year, so no surprises there.

Thursday the 13th looks even better. The morning has a 6ft south swell, 13-second period, and the energy is a touch lower at 1124, but the wind is a clean NNE offshore. That’s a major positive, giving you glassy, peeling faces. The swell direction is a perfect match for the break’s optimum, so expect some really nice, rippable waves. The afternoon picks up to 7ft, but the wind swings cross-offshore, so the morning is the standout session.

The 15th is another cracker. Saturday morning gives us a 7ft south swell, 13-second period, and the combined energy is a beefy 1560. With a light cross-offshore breeze, it’s clean and powerful. Again, this is expert territory with the size, but the quality is there for those who can handle it.

Now, the best of the best on offer is the Thursday morning (13th). The offshore wind on a 6ft south groundswell with a 13-second period, perfectly aligned to the break, is about as good as it gets for a clean, powerful session. The Friday morning (14th) is close, but the cross-onshore wind kills it.

After that, things drop off. From the 16th, the swell shrinks, the wind gets strong, and the scores plummet. You’ll see a long gap of about six days where the waves are just too small or messy. The 22nd and 23rd have a little bump of 3ft to 4ft swell, but with onshore or cross-shore winds, it’s a messy, low-energy affair. Not worth a trip.

The 25th afternoon shows a bit of life with a 4ft swell, but the period is a short 6 seconds, so it’ll be fat and weak. The 26th brings a bigger 6ft south swell, but the strong cross-onshore wind will turn it into a washing machine—more for kites than paddles.

So, in short: get on it for the 12th morning, the 13th morning, and the 15th morning. The 13th morning is the standout. After that, it’s a waiting game until the end of the month, but the forecasts are less certain that far out.

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.
