The Lowdown

Alright, this is Rusty checkin’ in from Geriba. We’ve got a pretty slow start here, so don’t get your hopes up for this weekend. The first few days are a write-off – Sunday and Monday are mostly messy with onshore winds and weak, short-period swell. Tuesday morning shows a little bump, but it’s still tiny and not worth paddlin’ out for.

The Real Window Opens Thursday, September 17th

Thursday morning is where it finally gets good. We’re lookin’ at a solid 5ft swell out of the south, with glassy conditions – that’s a rare treat, and it’ll be super clean. The combined wave energy is strong at 556, so there’s some punch in the water. This is the standout of the whole run. Geriba is consistent and handles a south swell well, so this should be a fun session, especially for intermediates and up. The water temp is about average for this time of year, nothin’ wild.

Thursday afternoon stays clean with a cross-off breeze, but the swell drops a touch to 5ft. Still a good option if you miss the morning.

Friday the 18th keeps the south swell goin’, around 4ft to 5ft, but the wind picks up hard from the northeast – 18-22 mph cross-off. That’ll keep things clean but make it a bit of a battle. The energy is high (up to 688), so the waves will have plenty of push.

The Lull and a Late Spike

From Saturday the 19th into the middle of the following week, things fade fast. Swell drops below 2ft for several days, and the combined energy dips into the weak range – we’re talkin’ 20-30s. Not much to work with, unless you’re after a flat spell and a tan.

Then, outta nowhere, on Friday, September 25th, there’s a spike. The morning shows a 5ft swell from the south-southwest with a long period of 14 seconds and huge combined energy of 1001 – that’s serious power. But here’s the catch: it’s onshore wind, so it’ll be messy and choppy. The swell direction (SSW) is a little off the optimum for Geriba, which likes it from the SE, so it might be lumpy. This one’s more for the experienced crew who don’t mind a bit of chop for some size.

After that, we’re back to small, marginal surf through the 27th and 28th. The last day, Monday the 28th, has a tiny 1ft south swell with offshore wind, but it’s barely a ripple.

So overall, Thursday the 17th is your best bet – clean, chest-to-head-high south swell, glassy morning. Friday’s also worth a look if you’re keen on more size and don’t mind the wind. The big spike on the 25th is a wildcard – could be a fun, lumpy day for the bold.

Stay stoked, and keep an eye on the forecasts – things can change.

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.
