The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s on the table for the next couple of weeks. It’s a bit of a mixed bag, but there’s some light at the end of the tunnel if you’re patient.

Right out of the gate, the first few days are a write-off. We’ve got weak, messy swells coming from the South with onshore and cross-onshore winds. The water temperature is sitting at 73°, which is just about average for this time of year, so no surprises there. Don’t bother paddling out Tuesday or Wednesday – it’s straight-up poor conditions.

The first sign of life shows up on Thursday, the 17th. We get a small bump in energy, with a S swell around 5 ft max and a cross-shore breeze. The combined energy is moderate (590 to 685), but conditions are still marginal and a bit crumbly. It’s surfable if you’re desperate, but I wouldn’t get stoked.

Friday, the 18th, sees a bit more size on offer, but the wind stays messy and it’s still just marginal. We get a clean cross-offshore breeze on Saturday, but the swell drops right back off to under 3 ft.

Now, here’s where it gets interesting. Sunday, the 20th, we get a spike of energy as a short-period E swell pushes in with a fresh offshore breeze from the NE. We’re looking at 6 ft surf with light rain and some clouds. The combined energy jumps into the moderate range (517). The wind is offshore and it’s clean, but the period is short (7 seconds) making it a bit lumpy and disorganised. It’s not perfect, but it’s the best we’ve seen so far.

The best day on offer in the first week is Monday, the 21st. A solid E swell is still hanging around at 5 ft to 6 ft, and the wind swings to the NNE in the afternoon, giving us a gentle offshore breeze and clean conditions. The combined energy sits at a moderate 304 to 406. The waves will have a bit more shape, and it won’t be too wild. Geriba is the spot to aim for if you can sneak out Monday afternoon. The swell direction (E) is not bang on the optimum SE, but the clean offshore wind makes up for it.

Tuesday, the 22nd, is also worth a look. We’ve got a clean 5 ft E swell with light offshore winds from the ENE. The combined energy is moderate (255). It’s a nice clean morning session for the intermediate crew. After that, the swell drops away.

The second week looks quieter again. The 27th of September gets a spike in potential with a very long-period S groundswell at 17 seconds and solid 2 ft to 3 ft surf. The combined energy is moderate (383 to 448). The morning of the 27th has a clean offshore breeze from the NE. That long period means it will have a lot of punch for the size, and it will be better shaped at a point or reef. It’s a standout for the second week, but you’ll need to be on it early before the wind changes.

Further out, the 28th of September sees a big pulse of energy with S swell pushing 8 ft and a combined energy hitting a very strong 1526 to 1983. That’s a lot of water moving around. However, the wind is onshore and it’s messy. This one is for experienced surfers only, and even then, conditions are poor. The best chance to ride it might be the morning of the 29th, when the wind goes light and cross-shore, with the swell still over 7 ft. It’s still big and the period is long (13 seconds), so it’ll be lining up but take caution.

Overall, don’t get too excited about the first few days. The standout is Monday the 21st for a clean, surfable wave. The 27th is a promising long-range option but keep your expectations in check.

Stay salty, folks.

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.
