The Lowdown

Alright, grab your board, 'cause things are about to get interesting here at Geriba. The water temp is sittin' at a pleasant 72°F, which is just about normal for this time of year, so no surprises there.

To start, we've got some solid groundswell filling in from the south, but the early part of this week is a bit of a mixed bag. Wednesday afternoon (that's the 9th) has some small 3ft S swell, but with a cross-off wind, it's just not coming together, and the energy is weak (150). Thursday the 10th starts to look a little better, especially in the afternoon. The NNE wind turns offshore, cleaning up a 3ft S swell with a nice 13-second period and moderate wave energy (328). It won't be pumping, but you'll find clean lines.

Now, Friday the 11th is the first real standout. Morning session has 4ft of sweet S swell with a long 14-second period and very strong energy (609). The gentle offshore NE breeze will have it glassy and lined up. This is the kind of day where you want to be in the water early. The wind holds offshore into the afternoon, but a cross-off breeze kicks up and the swell drops a touch, so morning is the call.

The weekend goes a bit ugly on us, unfortunately. Saturday the 12th and Sunday the 13th get hammered by strong cross-onshore winds that'll chop things up, even though there's plenty of swell. That 6ft S swell on Sunday afternoon has strong energy (708), but it's a messy cross-shore wind, so unless you're after a beatdown, give it a miss.

The start of the following week is tricky. Monday and Tuesday (14th and 15th) have a lot of wind, with the swell shifting east and the period dropping short, under 8 seconds. The offshore winds on those days will make the faces look clean from the beach, but that short-period east swell won't have the push or shape you want. It’s going to be a frustrating paddle.

But then we get a major pulse. Thursday the 17th is the standout of the whole forecast. We get a solid 8ft to 8ft S groundswell driving in with a very long 14-second period. The combined energy is enormous (1975–2160). With a light easterly cross-off breeze in the afternoon, the conditions are rated excellent for experienced surfers. This is big, powerful, lined-up swell. It's going to be a lot of water moving, so only paddlin' out if you know what you're doin'. This is the one to circle on your calendar.

After that big day, we get a drop-off into the weekend of the 19th, with small, weak S swell and clean but weak conditions. Not much to write home about.

Lookin' out to the 23rd and 24th, there's a promising pulse of S swell reappearing on Wednesday the 23rd with a 13-second period, and clean offshore wind. Then, the morning of Thursday the 24th has a big 8ft east swell with an offshore NNE breeze and strong energy (994). That's another expert-level day, with size and clean conditions. The afternoon stays clean with a light cross-off breeze. That second pulse is a solid shout for the end of the 16-day window, but it's a bit further out, so keep an eye on it.

For the best of the best, lock in Friday the 11th for the clean, fun S swell, and Thursday the 17th for the serious, powerful groundswell if you've got the chops. Geriba is always an exposed, consistent break, and crowds are often a factor here, so get in early.

Stay frothy.

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.
