The Lowdown
Righto, let's have a look at what's on the cards for Geriba. It's a classic beginner-friendly beach break, exposed to the south-east swells, and it can get crowded. The water temp is sitting at 72°, which is pretty much what you'd expect for this time of year, nothing unusual there.
First up, this weekend is a write-off. Saturday and Sunday, the 12th and 13th of September, are a complete no-go. We've got a fresh cross-onshore breeze on Saturday making a mess of things, and Sunday is light but onshore and messy. The swell energy is weak (174), and it's just not worth a paddle.
Things start to look up on Monday morning, the 14th. We get a moderate offshore wind from the NE, cleaning up 4ft of short-period (8 sec) easterly swell. The combined energy is moderate (319), so it'll be punchy. This is the first real window for a surf, and with the offshore breeze, it'll be clean. The afternoon holds similar promise with a 3ft southerly swell under NNE offshore winds.
Tuesday the 15th morning is the standout of this first week. It's small, with 4ft from the SSE, but the wind is a light offshore from the NE, making for glassy, clean conditions. The combined energy is moderate (367). For a beginner-friendly spot like Geriba, this is the pick of the bunch. The afternoon turns onshore and messy again, so get out early.
Wednesday the 16th and Thursday the 17th are a mixed bag. Wednesday is cross-onshore and choppy, with weak, long-period energy that won't shape up well here. Thursday morning is marginal, but Thursday afternoon is a beauty: a 5ft southerly swell (10 sec period, moderate energy at 548) with glassy conditions. That's a magic window for a clean session. The energy is moderate, but the glassy surface makes it top-notch.
Friday the 18th has good swell (5ft from the south), but the wind is a fresh cross-offshore, which can make it a bit lumpy and tricky despite being clean. The energy is strong (936), with a long 14-second period. This will hold shape well, but the wind might be a factor.
The following week: Saturday the 19th through to Wednesday the 24th sees cleaner conditions with light winds and offshore breezes, but the swell drops off. Swell heights from 1ft to 4ft, all from the south or SSE, with moderate energy. These are small, fun days, not for anything exciting.
Now, for the 24th of September, hold onto your board. We get a huge pulse of swell: 8ft on Thursday morning and peaking at 12ft for the rest of the day and into Friday. The combined energy rockets up to 7406, which is very strong. The swell is from the south with a very long 17-second period. This is groundswell of the highest order, but at 12ft, Geriba is going to be too big and dumpy for the average surfer. This is strictly for experts only, and even then, the sheer power will make it a handful. The offshore winds on Friday (NE at 19 mph) will keep it clean, but the size is the issue.
The weekend of the 26th and 27th sees the swell settle back down to 6ft to 3ft, with offshore winds and moderate energy. It'll be a nice, clean drop back to normal conditions after that massive pulse.
So, the best of it? For a clean, beginner-friendly session, Tuesday morning the 15th is your call. For a more powerful, glassy wave for the experienced crew, Thursday afternoon the 17th is the standout. And if you're a big-wave specialist, look at Thursday 24th through Friday 25th of September – but it's a beast and you'll need all your wits about you.

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.
