The Lowdown
Alright, Rusty here. Let's have a look at what's on the cards for Geriba over the next couple of weeks.
First off, water temps are feeling pretty average for this time of year, so nothing out of the ordinary there. The next few days are a bit of a write-off, with tiny, weak swell and poor conditions. But don't write it off just yet. The real action starts to build from Sunday the 9th of August.
We've got a solid pulse of groundswell arriving Sunday morning. The swell is a clean 5ft from the SSW with a nice long 14-second period, and the wind is blowing offshore from the NNE at 12 mph. That's a recipe for some beautiful, clean waves. The wave energy is really kicking in at 982 (moderate), and it's going to be a proper standout session. The crowd will be a factor here though, as it's often busy, so get in early. This is easily the best on offer for the whole outlook.
The swell hangs in there through the week, but the wind turns more onshore and messy, making things pretty average. The standout for the experienced crew comes on the morning of Wednesday the 12th of August. The swell is a solid 6ft from the S, with a 12-second period, and we've got a cross-offshore breeze. The wave energy is strong (1051), and it's described as excellent for experienced surfers. That's a good call if you've got the skills.
Then, the real cherry on top looks like Friday the 14th of August. The morning brings a 6ft S swell with a 14-second period, and it's dead glassy. Zero wind, totally clean. The energy is strong (1127), and the conditions are described as excellent for experienced surfers. This is a serious session for anyone who can handle a bigger, long-period groundswell on a beach break. It can get a bit tricky with the period at a beach, but on a day like this, the cleanliness will make up for it.
After that, the size drops off, and the wind gets howling again. The last week of the outlook is a total bust, with tiny, weak swell and strong winds. The run from the 17th of August onwards is a flat spell, with nothing worth paddling out for. A few days of small, messy windswell pop up, but nothing that will get your heart racing.
Summary: Clear your schedule for Sunday the 9th of August and Friday the 14th of August. Those are your two windows. The rest is a waiting game.
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.
