The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s happening over the next couple of weeks at Geriba.
Straight up, the first week is pretty flat and ordinary. We’ve got a long stretch of small, weak swell and the wind is mostly a fresh offshore or cross-off, but the waves just don’t have the size or energy to get excited about. From Saturday the 1st through to Monday the 10th, it’s a real waiting game. Most mornings offer a little clean offshore push, but the swell is tiny – nothing over 3 ft, and the combined energy is low to moderate (between 47 and 489). The water is sitting at 73°, which is about average for this time of year, so no surprises there.
The only standout in this whole 16-day window lands on Tuesday the 11th of August. Tuesday morning has the gear. We’re looking at a solid 8 ft S swell with a very long 14 second period, pushing a massive 2832 combined energy. The wind is glassy, dead calm from the NNW. This is serious groundswell – long period, heaps of power. It’s going to be too big for beginners, and even for most intermediates, but for the experienced crew, this is the session. The only caveat is that this kind of long-period south swell can be a bit straight at beach breaks, but Geriba can handle it well. The afternoon is a write-off on Tuesday with onshore junk, so get it early.
Wednesday the 12th still has some decent leftover swell – 7 ft in the morning, same S direction, period holding at 14 seconds, with a clean cross-off breeze. Energy is still strong (1663). It’s a solid option, but not quite the standout that Tuesday morning is. The rest of the second week drops back into the 3 ft to 5 ft range, with mostly cross-off or cross-onshore winds, and the energy fades. The last few days from the 15th have strong offshore winds (25 mph), which makes paddling a mission, so it’s really only for the fit and keen.
Overall, the best call is Tuesday morning the 11th. That’s the one to circle. Everything else is either too small, too windy, or just average. Crowds are often an issue at Geriba, so for that Tuesday morning, expect a crew.
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.
