The Lowdown
Alright surfers, Rusty here. Let’s talk about what Geriba has in store for us over the next couple of weeks.
Geriba is a consistent, beginner-friendly wave that’s open to the swell, and it’s often got a crowd out. The water is sitting at around 73°F, which is pretty average for this time of year.
The week kicks off quiet. Wednesday the 2nd is a total write-off with messy, cross-on winds and weak, short-period swell. Not worth paddling out.
Things start to look up on the morning of Thursday the 3rd. We’ve got a clean 6ft swell rolling in from the south with an 11-second period. The wind is offshore from the northeast, making for some tidy, clean lines. The combined energy is solid (906), and this is shaping up to be a proper standout session. This is likely the best on offer—size is manageable for intermediates, and it'll be fun for anyone who can read a wave.
Friday the 4th drops back a bit in size to around 3ft from the SSE, but with clean offshore breezes in the morning and light cross-off in the arvo, it'll be a fun little wave for a longboard or a bigger board. Combined energy is moderate (271).
Saturday the 5th morning is a gem for the light crew. Glassy conditions with rain showers and a little 3ft easterly swell. It won't be powerful, but the peace and clean surface will make it a nice session if you’re keen for a quiet paddle. Energy is moderate (208).
Sunday and Monday the 6th and 7th are pretty average—wind comes onshore, bumps things up, and the waves get sloppy. Not great.
Tuesday the 8th is another highlight. Glassy morning with a clean 5ft south swell, and by the afternoon it jumps a touch to 5ft with light cross-off breezes. Combined energy climbs to 531 and conditions are clean. This is a solid, fun day for all levels.
A bit further out, on Friday the 11th, we’ve got a promising morning with a clean 6ft swell from the east, light cross-off winds, and combined energy of 519. The period is a touch short at 9 seconds, but it’ll still offer fun, shapey waves. Could be another good one for the intermediate crew.
After that, the second week gets messier. Winds shift onshore, and while there are some moderate pulses of swell, the quality drops. A note for Sunday the 13th afternoon: a long-period 15-second south swell shows up but with strong cross-off winds—combined energy is 411, but the conditions just aren't friendly for paddle surfing.
The very end of the forecast, Thursday the 17th, sees a solid but ugly 7ft south swell with a very long 15-second period and strong onshore winds. Combined energy hits 1974, which is powerful, but the wind is lumpy and rough. For that setup, you’d be better off looking at it for a kite session than a clean surf—too much chop and power for fun paddling.
In short, the clear winners are Thursday the 3rd and Tuesday the 8th. If you can only surf once, make it one of those.
Stay stoked,
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.
