The Lowdown
Alright, let me break this down in feet and miles per hour for those who work in the old numbers.
Right off, Geriba’s got a couple of sessions worth a dawn patrol. Water’s about normal for this time of year, nothing weird.
Monday the 14th and Tuesday the 15th kick things off with some fun, waist-to-shoulder-high waves (2 to 4 ft) out of the S/SSE. The wind turns offshore from the NE on Tuesday afternoon – that’s clean, lined-up, proper. Combined wave energy is moderate on Tuesday arvo, around 348. Not huge, but the quality is there.
Then Thursday the 17th is the big one. Swell hits about 5 ft from the S, 10-second period, and the combined energy jumps to 652 – solid, powerful. Wind is light cross-shore from the ESE, so the wave face stays pretty clean. This is the best size and energy of the whole stretch. Intermediate to advanced surfers will love it; beginners might find it a bit much.
After Thursday, it’s mostly disappointment. From Friday the 18th all the way through Monday the 28th, the wind shifts cross-off or onshore, and despite some big energy numbers on the 20th (538) and 21st (504), the wave quality is poor. Swell direction goes E with a short 6-8 second period – weak, choppy, messy. On the 18th through 20th, with 25-30 mph winds, a kite might be more fun than a paddle board.
Only other moment of hope is Tuesday the 22nd morning. Glassy, 5 ft from the E, but with that short period it’ll be a bit soft. Still, glassy is glassy.
So, your standout is Thursday the 17th. Best swell, best energy, decent wind. Tuesday the 22nd morning is a backup for the glassy lovers. After that, save the gas money.

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.
