The Lowdown
Alright, grab your board and let's see what Geriba's got cooking. The forecast starts with a bit of a lull, but we've got a solid run of surf coming into the second week.
The water's sitting at a warm 73°F, which is about average for this time of year, so no surprises there.
The first real action kicks off on Friday afternoon, August 14th, with a 6ft S swell rolling in at a 13-second interval. The energy's moderate (1124), but the wind is a cross-on from the SE, making it a bit choppy. It's a marginal start, nothing to get too excited about.
Saturday morning, August 15th, is where things start to get interesting. The swell pushes up to 8ft from the SSE, packing a solid 13-second period and strong energy (2113). The NE wind is cross-off, keeping the waves clean. This is a solid session for experienced surfers, as it's a bit too big for beginners. The afternoon though, the wind shifts and it gets messy.
Sunday, August 16th, the swell drops quickly to 4ft, but the wind stays clean from the ENE. It's smaller, but still rideable. After that, we hit a dry spell. From Monday, August 17th, right through to the end of the week, the swell drops out completely. There's a lot of clean, offshore wind, but the waves are tiny, barely a ripple. The energy is weak (as low as 17), and it's just not worth paddling out for.
The waiting game pays off. The real standout is shaping up for Tuesday morning, August 25th. We've got a 6ft SSW groundswell with a 12-second period, and strong energy (1080). The wind is offshore from the NE, giving us clean, lined-up waves. This is the best of the forecast, excellent conditions for experienced surfers. The swell direction is a perfect match for the break's optimum from the SE, making for some proper walls.
The day before, Monday, August 24th, also has some size, with 8ft S swell, but it's a bit cross and lumpy, so it's a secondary option.
Wednesday morning, August 26th, is worth a mention too. A 5ft S swell with very light offshore N wind, and the energy is moderate (668). It'll be clean and fun, but not the standout.
So, to wrap it up: the first week is a write-off after the initial pulse. Wait for that Tuesday the 25th for the best chance of scoring some clean, punchy waves. The longer-range stuff is promising, but as always, keep an eye on the forecasts.

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.
