The Lowdown
Alright, Rusty here. Let's have a look at what's on the cards for the coming weeks.
Right, straight off the bat, it's a bit of a flat start. We're looking at tiny, weak swells through the first few days, nothing worth getting wet for. The water temp is sitting at about 72°, which is pretty much normal for this time of year, so at least it's not a shock to the system.
The first real sniff of action comes around Friday the 24th. That morning we see a small pulse of 3ft swell from the east, but it's got a short period of 8 seconds and a cross-onshore breeze. The combined energy is weak (111), so it's not really going to shape up. By the afternoon, the wind swings onshore from the south, but the swell bumps up a touch to 3ft from the SSW. Still, it's a poor outlook.
Things look a little more promising on Saturday the 25th. The morning sees a 4ft swell from the south, and the wind is a clean offshore from the NNE. The combined energy is moderate at 288. This is a better chance for a surf, but the overall forecast is still marginal. The afternoon is similar but with a cross-offshore wind, which still keeps it pretty clean.
We get a bit of a lull through Sunday the 26th and Monday the 27th as a strong south-westerly wind and a long-period swell (14 seconds) create a lot of chop and bump. The energy is strong (503 and 594), but it's not surfable.
The next window appears on Tuesday the 28th. The morning brings a 3ft south swell with a clean offshore from the NE. The combined energy is moderate (231) and the wind is offshore, so it'll be clean. It's not a standout, but it's a solid session.
There's another gap of small, weak surf until Saturday the 1st of August. That morning we see a 4ft south swell building, with a moderate period of 11 seconds and a clean cross-offshore breeze. The combined energy is moderate (363). It's a marginal forecast, but the afternoon looks better with a similar 4ft swell and a longer 12 second period, and the energy jumps to 680.
The standout, and the one to circle on the calendar, is Sunday the 2nd of August. The morning at Geriba is looking good. We've got a clean 4ft south swell with a nice 13 second period, and the wind is a clean offshore from the NE. The combined energy is strong (557). This is a proper groundswell with good energy and clean conditions. It's a point break setup, so that long period will wrap in nicely. The only downside is that crowds are likely, so get there early. This is the best on offer.
Monday the 3rd of August still has some decent 3-3ft swell, but the wind is a bit more cross-offshore. Tuesday the 4th of August morning is a real treat – glassy conditions with a 4ft east swell and the wind is gone. That's a major positive for clean, open faces. The period is short at 7 seconds, so it'll be a bit fat, but the glassy surface will make it fun.
After that, the swell drops off again into the second week, with a small pulse from a long period (16 seconds) on Wednesday the 5th of August, but the wind is strong and it's just not worth the effort.
So, to sum it up: the start is flat, but hang in there. Sunday the 2nd of August at Geriba is the pick of the bunch.
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.
