The Lowdown
Alright, Rusty here, let’s look at this in feet and miles per hour.
The first few days are small and not worth getting wet for. Thursday the 6th has 2ft south swell, but the wind is a moderate offshore from the NNE at 15 mph, keeping it clean. The wave energy is weak (125). Friday the 7th is even smaller, just 1ft from the SSE, with lighter offshore wind but not enough push.
Saturday the 8th sees a jump to 3ft, but it’s a short-period 5-second south swell, so the waves are fat and weak. The afternoon brings a long-period 18-second groundswell, but the energy is moderate (262) and the cross-offshore wind won’t help the shape at a beach break.
Sunday the 9th morning is the first real standout. We’ve got 5ft of SSW groundswell with a 14-second period, and the wind is offshore from the NE at 12 mph. The combined energy is strong (887). The water temp is 73°, about average for this time of year. For a beginner spot, this is just on the edge of being too big for learners, but it’s still manageable for progressing surfers. Crowds are likely, so get there early. The afternoon gets choppy with cross-onshore wind.
Monday the 10th and Tuesday the 11th are blown out with onshore winds and 4ft to 6ft of messy south swell. High energy (over 1200) but the wind ruins it.
Wednesday the 12th morning is another good session. Glassy conditions with a light easterly breeze at 3 mph, and a 6ft south swell at 12 seconds. The energy is solid (754) and the clean conditions make it very surfable.
Thursday the 13th and Friday the 14th have offshore winds in the mornings, with 6ft and 3ft south swells. Friday morning has a very long period of 15 seconds and strong energy (847), which will produce clean, lined-up waves, though the long period can make beach breaks a bit straight.
The second week gets rough. The 15th and 16th have 6ft to 8ft of swell with cross-onshore winds, making it choppy and more of a kite day. The 16th has a 7ft short-period east swell (7 seconds) that’s clean in the morning, but the wave quality will be weak.
From the 17th onwards, the wind howls at 20 to 28 mph, and the waves drop to 2ft to 5ft, making it hard to paddle and not worth it. There’s a small window on Wednesday the 19th morning with a light 6 mph offshore and 4ft east swell, but it’s not a standout.
The best sessions are Sunday the 9th morning and Wednesday the 12th morning. Clean, offshore wind, solid south swell, and good energy.
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.
