The Lowdown
Alright folks, Rusty here. Let’s cast an eye over the next couple of weeks for Geriba. It’s a bit of a mixed bag on the horizon, but there are a couple of windows that’ll get the heart pumping.
Right off the bat, we’re looking at a pretty flat start. The first few days are a write-off with tiny, junky waves. The water temperature is sitting at 73°, which is pretty much bang on normal for this time of year, so the wetsuit decision is easy for now.
The first real glimmer of hope comes on Thursday, the 3rd of September. The morning is the standout. We’ve got a solid 6 ft south swell with a clean 10-second period pushing in. The combined energy is a solid 615 (moderate), and the wind is blowing clean offshore from the NE. This is going to be a fun session, with some proper shape to the waves. It’s a beginner-friendly spot, but with that size, it’s a good step up for those looking to push into something a bit more substantial. Keep an eye on the crowd factor, as it can get busy here. The afternoon turns nasty with a howling 25 mph cross-offshore wind, so make the most of the morning.
Friday the 4th is a solid follow-up. The morning sees a 3 ft south-southeast groundswell (11-second period) with a light offshore NNE breeze. The energy is at 257 (moderate), and it’s going to be clean and lined up. Another very good session. The afternoon holds up alright too with light winds.
We then hit a lull. Saturday the 5th drops off quickly, and from Sunday the 6th through to Tuesday the 8th, we’ve got onshore winds and lumpy conditions. There’s a pulse of 6 ft to 6 ft south swell on Monday the 7th, but with a cross-onshore wind, it’s going to be messy and not much fun for a paddle. If you’ve got a kite, that Monday might be your window.
Wednesday the 9th has some clean-ish waves, but it’s marginal. The real next highlight is a very long-range pulse. On Thursday the 10th of September, we’re looking at a 5 ft south swell with a very long 13-second period. The energy is a thumping 847 (strong). However, the wind is a fresh 22 mph cross-offshore. That’s a lot of wind for a clean wave. It’s a promising forecast, but that far out, it’s a bit of a tease. The swell direction is perfect for Geriba, but the wind needs to settle.
Jumping forward to the 16th of September, the Tuesday morning looks like a nice little payoff. We’ve got a 5 ft easterly swell with a light offshore breeze from the NE. The energy is 495 (moderate), and it’s clean. Not a monster, but a proper, fun, user-friendly wave for all levels.
Overall, the best bet is hands-down the morning of Thursday the 3rd of September. That’s the one to circle. The 16th is a solid backup. The long-range stuff on the 10th is exciting on paper, but treat it with caution until we get closer.
Stay stoked.
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.
