The Lowdown
Alright mate, I'll give you the straight-up honest forecast for the region. This is where I call it like I see it.
First up, these next few days are a total write-off. Geriba is going to be a mess. That Sunday, the 16th, has a bit of size at 5 ft from the south, but the wind is a stiff cross-off, making things lumpy. The energy is moderate, about 772, but the whole thing is just a marginal, messy affair. It’s not worth paddling out for. From Sunday through to the 22nd, we’re looking at a long, dry spell with next to nothing. The swell drops to ankle-snappers, and the winds just don’t cooperate. I’m talking at least five days of flat or near-flat conditions. It’ll be frustrating, but that's how it goes sometimes.
Now, let's look at the light at the end of the tunnel. There’s a real pulse of swell coming from the south. It starts to show up on the 25th of August. This is the standout period. On Tuesday the 25th, we’re looking at a solid 8 ft south swell in the morning, with the energy climbing right up to 2001 (strong to very strong wave energy). The wind is offshore from the NE at 12 mph. This means clean, groomed faces. This is proper surf for experienced surfers only, as it's well over 8 ft. The period is a long 13 seconds, so there'll be plenty of power between waves. The afternoon holds at a more manageable 7 ft.
The 26th of August is a close second, and honestly, it might be the pick of the bunch. The swell holds solid at 7 ft from the south, with a very long period of 14 seconds. That is a groundswell with serious energy. The wind is offshore again, this time from the north at 6 mph, making it glassy. The energy reading is 1834 (strong). Again, this is strictly for the experienced crew due to the size. The very long period (over 15 seconds) on these southern swells can make them a bit straight at the beachbreak, but with the offshore wind they’ll hold up well.
After that, the swell drops off again quickly. The 27th sees the wind turn onshore, spoiling the party. By the 28th, there’s a small clean 3 ft wave to be had on the Friday morning, but it’s a far cry from the mid-week pump.
So, to put a pin in it: the next week plus is a bust. If you are a beginner, stay home till the 25th because that swell will be way too big. For everyone else, lock in the 25th and 26th of August. The 26th Wednesday morning with the glassy north wind is the one I'd be stoked on. It’s a promising run, but it’s far out, so keep your fingers crossed.

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.
