The Lowdown
Alright folks, Rusty here. Let’s look at what’s on the cards for our stretch of coast. We’ve got a bit of a wait for the really good stuff, but the second half of the outlook is looking like it could be a ripper.
Things start off a bit messy on Thursday with a solid 6 ft S swell rolling in, but that 22 mph cross-off wind in the afternoon is going to chop it up. The morning is better, with a clean 12 mph offshore breeze, and the combined energy is moderate (906). The water temp is sitting at 73°, which is pretty much normal for this time of year, so no surprises there.
Friday morning is your first real call. Geriba is waking up to a clean 4 ft SSE swell with a moderate 16 mph offshore. The wave energy is 338, so it’s not huge, but it’s clean and the conditions look good. Friday afternoon drops off a bit with a cross-shore breeze, so get it early.
We’ve got a bit of a flat spell over the weekend. Saturday morning is glassy (2 ft) but tiny, and Sunday is pretty much a write-off with onshore winds and weak energy. Monday and Tuesday are still a bit of a slog, though Tuesday morning is worth a mention: a 5 ft S swell with a clean 6 mph offshore (energy 591) means there’s a wave to be had, but it’s not the standout.
The real action kicks off on Tuesday, 15 September. A big 8 ft S swell is pushing in with a fresh 19 mph offshore. That’s strong (energy 1474), and the offshore wind will keep it clean. This is solid, proper surf. For the experts, that’s a good thing. For beginners, it’s a bit too much.
But the absolute standout is Friday, 18 September. Geriba is going to be pumping. A 8 ft S groundswell with a very long 17-second period. The combined energy is a massive 3960 – that’s strong. It’s glassy in the morning, so the waves will be perfect. This is the kind of swell that makes the drive worth it. It’s a bigger wave, so only for experienced surfers, but if you’re comfortable, this is the best session of the entire outlook. The afternoon shifts a bit with a light cross-on, but the morning is the call.
All in all, we’ve got a quiet start, a few decent mid-week options, and then a potential classic on the 18th. Keep your eyes on that one.
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.
