The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s coming up for Geriba over the next few weeks. It’s been a bit of a mixed bag, but we’ve got a couple of sessions that are going to be worth the paddle out.
The overall pattern shows a solid start to the period, with a nice pulse of S swell arriving on Monday the 7th, but the real gem might be hiding a bit further out. We’ve got a lot of action in the first week, then a bit of a lull and some messy conditions before a standout session on the 15th.
We kick off on Monday afternoon, 7th September. The water is sitting at 72°, which is about average for this time of year. It’s cloudy with a glassy sea state and a light WSW breeze at 3 mph. The surf is a clean 6 ft of S swell, with a period of 11 seconds. The energy is moderate (847). This is a solid, fun wave for beginners and intermediates alike. The crowd is often around, so expect a few friends out with you.
Tuesday morning, the 8th, sees a drop in size to 5 ft, but the wind picks up and turns cross-off from the NE at 12 mph. The energy drops a bit (663). It’s still surfable, but the morning’s light rain takes the shine off. Tuesday afternoon gets windier and the quality drops. Wednesday the 9th is a bit of a write-off, with strong offshore winds all day, though the afternoon turns glassy with a tiny 3 ft swell and a bit of heavy rain. The energy is weak (335). Not the best.
Thursday the 10th has a nice 3 ft S swell with a 12-second period, and the wind is offshore in the morning and cross-off in the afternoon. The energy is moderate (314-323). It’s a clean but small offering. The real standout in the first week looks like Friday the 11th. Morning session offers a 4 ft S swell, a 14-second period, and a clean offshore NNE breeze at 16 mph. The energy is solid (514). The water is clean and the waves are pulsing. The afternoon is almost as good with a 3 ft swell and 13-second period.
That’s the best of the first week. Saturday the 12th is a write-off with poor conditions and small, choppy waves. The whole of the following week gets a bit dicey. The swell builds again, but the wind is mostly cross-on, making things messy. Sunday the 13th has a 7 ft swell from the S, but the cross-onshore wind makes it a pretty average affair (energy 1745). The 14th is similar, with an 8 ft swell but strong cross-off wind, which keeps it clean but pushes the size beyond what’s fun for most.
Now, the true standout is Tuesday the 15th. The morning session is calling for a 7 ft SSE swell with a 13-second period, and the wind is glassy from the NW at just 3 mph. The energy is very strong (1889). This is a big, clean, powerful swell. The break is exposed, so it’ll be handling the size well. This is one for the experienced surfers – at 7 ft, it’s big and the longer period (13 seconds) means it will have plenty of punch. The afternoon stays clean but the wind gets strong and offshore. The energy is still massive (1748). This is the day to clear your schedule.
After the 15th, the swell slowly backs down. The 16th has more onshore wind, the 17th has a moment of hope with a small 3 ft clean swell, but the rest of the week is a mix of choppy, cross-on conditions and small, short-period windswell. The 18th and 19th are full of messy, short-period E swell that is not worth your time. The 20th has a brief moment with a 6 ft E swell and a strong offshore wind, but it’s a messy setup. The final few days, the 21st and 22nd, are very small and weak.
So, to sum it up: the best session is undoubtedly Tuesday the 15th morning. Get there early for the glassy, big, powerful swell. The Friday the 11th morning is also a very solid, clean option if you want something more manageable. The rest of the period is either too small, too windy, or too messy to get excited about.
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.
