The Lowdown
Alright folks, this is Rusty, and I’m lookin’ at the next couple of weeks for our local stretch. The forecast is a bit of a mixed bag, with a solid kick of swell early on but plenty of wind to deal with, and a big lull later. Let’s get into it.
The first real sniff of action comes Sunday morning, August 9th. The ocean’s gonna fire up with a clean 5ft SSW groundswell pushin’ through, with a long 14-second period. The wind is a dream – light and offshore from the NNE, so expect some beautifully clean lines. The energy is solid, with a combined swell energy reading of (1106). This is proper stuff, but it’s got some punch. At 5ft, it’s edging into the size that might be a handful for the beginners, but for the experienced crew, it’s a green light. The water’s sitting at 73°, which is about what you’d expect for this time of year, so nothing out of the ordinary on that front.
The standout window, without a doubt, is the Friday morning, August 14th. The wind is dead flat, glassy as a mirror, with a solid 6ft south swell rolling in at 14 seconds. The energy is pumping at (1309), and with those conditions, Geriba is going to be absolutely pristine. That’s the morning to circle on the calendar. The swell is a little over 5ft, so it’s a bit more serious, but with the wind letting it breathe, it’s going to be a memorable session for anyone who can handle it. Just keep in mind that the crowds can be a thing here, so get there early.
After that, the rest of the window gets messy. The wind swings around onshore and cross-shore, chopping up the 5ft to 8ft south swells through the start of the week. The energy is high, readings over 1500, but the quality is just not there. A lot of it will be a battle against the wind. By the 16th, you’ll see a drop in swell size, and by the 17th and 18th, it’s pretty much flat as a pancake, with tiny waves and hardly any energy.
There is a glimmer in the second week. On the morning of Wednesday, August 19th, the wind goes glassy with a little 4ft east swell. It’s gonna be clean, but small. And then on Friday, August 21st, a cleaner 5ft SSW groundswell arrives with light offshore wind, making for another good look. The energy is moderate at (672), but it’s a much better prospect than the junk around it.
So, to sum it up: the best of the best is Friday morning, August 14th for the glassy, powerful south swell. Sunday morning, August 9th, is also a solid option for the bigger, clean swell. The middle of the week and the following days are mostly a write-off due to wind, and the last few days of the outlook are tiny. Keep an eye on that Friday 21st for a late-week reward.
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.
