The Lowdown
Hey folks, Rusty here with a look at the surf ahead. We got a slow start to this run, no two ways about it. The next few days are a total no-go. Onshore winds and sloppy surf are making things pretty uninviting.
The first few windows of surf from the 16th to the 19th are pretty average at best. We see a 0.9m to 1.4m SSW to S swell, but the wind is a killer. It’s cross/on-shore or just plain messy. The water’s got a bit of a chop on it, and it’s just not worth the paddle out unless you're dedicated to the cause. Combined energy is up to 635, but it's a junky sort of energy.
Things start to clean up for Friday the 19th and Saturday morning, but there’s not much size. The ocean is getting some shape to it, but it's still small and weak.
Now, hold on to your boards because we get a little pulse of East swell late on September 20th and into Monday the 22nd. This is our first real chance at something decent. The winds turns offshore and the whole lineup gets clean. It’s not huge, maybe only 1.6m, but the combination of clean conditions and some juice makes it the best we've had. The short period of around 7-8 seconds will keep it a bit crumbly, but it's fun and clean. This is when you want to be out there in the water.
Then it goes quiet again. A few days of dribble, and nothing really catches the eye. The ocean seems to take a breath.
But the real story here is what’s coming. Take a look at the forecast for the 1st of October. We got a 1.6m south swell lining up with a light offshore wind and clean, glassy conditions. All the energy signs are looking good, and the wave direction is spot on. The long-range models are showing something with a lot of potential, and the overall energy is the healthiest we've seen.
It’s a waiting game, but that final window is where you want to be. I don’t want to get too excited this far out, but damn, it looks like it’s shaping up to be the day to get a few sneaky ones. Keep your fingers crossed.
Stay sharp.
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.
