The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
Right off the bat, we're looking at a pretty flat and quiet start. The first few days are a write-off, with tiny waves and not much to get excited about. The real action is tucked away in the second week.
Geriba is our only named break on the cards, and it's a consistent, beginner-friendly beach break that's exposed to the swell. The water temperature is sitting at 72°F, which is bang on average for this time of year – nothing to worry about there.
The first real window of opportunity doesn't open until Thursday, September 3rd in the morning. We've got a solid 8ft swell rolling in from the south with an 11-second period, and the wind is dead glassy from the east. That's a recipe for clean, powerful waves. The combined energy is sitting at 1,276 – a moderate push – and it's going to be a standout for experienced surfers. The swell is a bit too hefty for beginners, though. The afternoon cleans up with cross-offshore winds, but the conditions are a touch more marginal.
Then we hit a bit of a lull. Friday and Saturday are small again, with messy onshore winds and weak energy readings in the 200-500 range – not worth paddling out for.
The real standout of the whole forecast is Monday, September 7th morning. We're looking at a massive 12ft southerly groundswell with a long 14-second period. The wind is glassy, and the combined energy is a whopping 5,152 – that's serious, powerful stuff. This is strictly for experts only, and even then, it might be too big for the break itself. The afternoon stays big with a 15-second period and 6,145 energy – monstrous. This is a heavy, heavy swell that will be breaking straight and fast, so only the most experienced will be out there.
Tuesday, September 8th is still pumping, but it's dropping. The morning gives us a 10ft southerly swell with a 15-second period, moderate offshore winds from the northeast, and energy at 4,279. Still for experts, but a little more manageable. The afternoon drops to 8ft with cross-offshore winds.
The following days see the swell taper off, with some clean windows on Wednesday, September 9th morning (7ft, glassy, 1,350 energy) and a smaller, glassy morning on Sunday, September 13th (4ft, glassy, 414 energy) – that one could be a fun, smaller-scale option for the beginners if the tide lines up.
Overall, the best bet is the Thursday, September 3rd morning for experienced surfers looking for clean, solid waves. The Monday, September 7th and Tuesday, September 8th sessions are for the hardcore chargers only. The rest is small and messy, or too big and windy.
Keep your eyes on the forecasts for that second week – it's got some serious potential.
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.
