The Lowdown
Alright folks, Rusty here. Let's have a look at what Geriba's got cookin' for us over the next couple of weeks.
The first few days are a bit of a write-off, I'll be honest. We've got a weekend of poor conditions ahead, with onshore winds messing up even the small swell that's around. The real action doesn't start to build until the middle of next week.
Saturday, the 5th starts off with a promising little glassy morning – a tiny 3ft swell from the east, but the water's a lovely 72°, which is about average for this time of year. You could get a few fun ones on a longboard, but the energy is weak (187). The afternoon turns sour with a strong cross-on breeze, so call it a half-day.
Sunday, the 6th is a total loss. Strong onshore winds and building swell make for a messy, choppy mess. The afternoon sees a raw 6ft southerly swell (449 energy) but it's blown out.
Monday, the 7th is still marginal. The swell hangs around 7ft from the south (835 energy), but it's cross-onshore and the tide is likely a factor. Not one for the quiver.
Tuesday, the 8th is where we start to see some hope. A solid 5ft south swell (474 energy) and a clean, moderate offshore breeze from the NE. This is a good session for the experienced crew – the wave height is getting up there, but not too big for a good paddle. The morning window is the pick.
Wednesday, the 9th has a standout morning. A clean 6ft easterly swell (544 energy) with a gentle offshore from the NNE. The period is a bit short (8 seconds), so it'll be a bit sectiony, but for a fun, punchy wave on a longboard or fish, this is a top call. The afternoon changes with onshore wind, so get it while it's good.
Thursday, the 10th is clean again. Morning offshore winds with a 4ft south swell (382 energy) and a longer 12-second period, meaning better shape. The afternoon goes glassy with a 4ft south groundswell (487 energy). A solid day for a sunset session.
Friday, the 11th is the pick of the first week. A glassy morning with a 4ft, 14-second south groundswell (588 energy). That's a proper long-period groundswell – it'll be lining up with beautiful shape, perfect for a point break or reef. Get on it early. The afternoon stays clean with a cross-off breeze.
Saturday, the 12th and Sunday, the 13th see the swell drop right off. Small, weak waves and strong winds make it a weekend for other plans.
Monday, the 14th is a big warning. A massive 7ft south swell (1676 energy) hits with strong onshore winds. This is a dangerous, powerful, blown-out mess. Only for the insane, or the kite surfers – the setup looks far more interesting for them than paddle surfing.
Tuesday, the 15th is the absolute standout. A 8ft, 12-second SSE swell (1491 energy) with a clean cross-off breeze. This is heavy, powerful surf for experienced surfers only. The wave energy is massive. If you're a competent surfer, this is the day to be in the water. The morning will be firing.
Wednesday, the 16th through to Friday, the 18th taper off. The swell drops and the wind becomes inconsistent, with some onshore slop and rain. Not worth the paddle.
Saturday, the 19th is another cracker for the second week. A 5ft, 16-second south groundswell (1263 energy) with a clean cross-off breeze. This is a very long-period groundswell, so expect long, clean lines and long waits between sets. That's a classic, powerful, clean session for the experienced surfer.
Sunday, the 20th wraps it up with a small, clean morning but a short-period east swell (7 seconds) that will be weak and messy.
Best on offer: Without a doubt, Tuesday, the 15th for the big swell and clean conditions. The Friday, the 11th and Saturday, the 19th are also top-tier for their groundswell quality and glassy morning windows. For the average surfer, Wednesday, the 9th morning is the most accessible standout.
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.
