The Lowdown
Alright, let's talk about Geriba. The forecast starts off slow, but there's some serious power brewing for the end of the month.
The first week is pretty much a bust. From the 17th through the 24th, the waves are flat to tiny, with weak energy readings dropping from 222 down to nearly nothing. Even when a little bump shows up, the conditions are just poor. It’s a long, quiet run with nothing worth suiting up for.
Around the 25th and 26th, you'll see some waist-high south swell push in, but the wind is messy and blows onshore, so it's not really a goer. You'd have to be pretty keen.
Now, circle Wednesday the 29th. That morning is the real deal. Geriba will be clean with 4ft south/southeast groundswell, a 14-second period—those are proper, long lines. The wind is light offshore out of the NE, so it’ll be glassy perfection. The combined energy reads 752 (moderate), so there's plenty of punch. It's normally a friendly wave, but with that size and power, it'll be fun for most.
The window closes fast, though. That afternoon a strong SW wind messes it up. The following days see a big pulse of swell, over 8ft, but it's hammered by strong cross-shore winds and lumpy conditions—experts only, if anyone. The 31st and 1st of August offer cleaner conditions with big swell again (8ft to 6ft), but the wind is howling over 25 mph, making it a battle. The water temp is 72°, which is about average for the time of year.
So the 29th morning is your best bet. Don't sleep on it.
Stay thirsty,
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.
