The Lowdown

Alright folks, Rusty here. Let’s break down what’s on the menu for our local stretch.

We’re starting with a bit of a slow burn, but there’s a wave or two worth paddling for if you pick your moments. The first real action kicks off on Wednesday the 12th of August, with a solid 7ft S swell rolling in, but the wind is a cross-off from the ENE at 12 mph, keeping things clean. The water temp is sitting at 73°, which is about average for this time of year, so no thermal surprises. The wave energy is moderate (1290) and the period is 12 seconds, so there’s some push behind it. It’s a fair session, but nothing to write home about.

Thursday the 13th of August is where it gets interesting. Morning session at Geriba is the standout of the whole run. We’ve got a 6ft S swell with a 13-second period, and the wind is offshore from the NNE at 9 mph. That’s glassy, clean conditions, and the moderate wave energy (1124) is working with you. This is excellent surf for experienced surfers—solid, well-shaped waves with that long-period groundswell feel. Head out then.

The rest of the week fades quickly. Friday the 14th and Saturday the 15th get messy with onshore and cross-shore winds, lumpy conditions, and stormy weather. Wave energy spikes a bit but it’s all chop. Not worth the paddle.

Then we hit a dead zone. From Sunday the 16th of August through to the end of the third week of August, it’s flat or tiny. Swell drops to below 3ft, the wind is howling, and the wave energy numbers are in the low double digits. It’s a solid 5-6 day gap with no real surf on offer. You’d be better off waxing your board and waiting.

Things start to bubble again on Sunday the 23rd of August. The 4ft SSW swell is a hint of life, but it’s still small and the wind is fresh. Not a goer.

The real second act comes on Monday the 24th of August. Morning session at Geriba sees a 7ft S swell with a 13-second period, and the wind is offshore from the NE at 12 mph. The wave energy is strong (1673) and the conditions are clean with moderate offshore winds. This is excellent for experienced surfers—bigger, more powerful waves. It’s a promising call, but it’s a week away, so keep an eye on it.

Tuesday the 25th of August afternoon is also a looker. A 8ft S swell, 15-second period, very long-period groundswell, and light ENE winds at 9 mph. Wave energy is strong (2252). This is the kind of swell that’ll wrap nicely around the point. It’s excellent for experienced surfers, but the long period means it’ll be a bit more drawn out—perfect for a reef or point setup.

After that, the wind turns onshore again and the surf drops off. The 26th and 27th are messy and choppy.

So, to sum it up: Thursday morning the 13th of August is your top pick—clean, offshore, solid swell. The Monday the 24th of August morning and Tuesday the 25th afternoon are the long-range standouts, but they’re less certain. The water’s average temp, no crowds mentioned at Geriba, so you might have it to yourself.

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.
