The Lowdown

Alright, Rusty here. Let’s have a look at what the ocean’s got cooking for us at Geriba over the next couple of weeks.

First thing you’ll notice is we’ve got a quiet start. The first real chance to get wet comes on Thursday, the 10th of September. It won’t be anything to write home about, but it’s a start.

Thursday afternoon brings in a 3 ft S swell with a period of 12 seconds. The wind is light out of the E, cross-off, keeping things clean. The combined swell energy is moderate at 323. Water temp is sitting at 72°, which is pretty much average for this time of year, so no surprises there.

Friday the 11th is where things start looking up. The morning session is the pick of the early days. We get a clean 4 ft S swell, a longer period of 14 seconds, and a nice offshore breeze from the NE at 9 mph. That’s good energy (605) and clean lines. Afternoon stays clean with a 4 ft SSE swell, but it takes a small step back with cross-off wind.

Saturday the 12th and Sunday the 13th are write-offs. Onshore winds and choppy conditions for both days. Saturday has 2 ft to 3 ft with cross-on and onshore wind, and Sunday is similar with short-period, weak swell. Don’t bother.

Monday the 14th brings a glimmer. The afternoon has a 6 ft E swell, but it’s short period (7 seconds). The real story is the wind goes glassy. That’s rare. The combined energy is strong at 566, but the short period means it’ll be a bit mushy and close-out city for some. Still, glassy conditions make for a fun session if you pick your peaks.

Tuesday the 15th is solid with offshore winds in the morning. A 5 ft ESE swell with a period of 8 seconds and moderate energy (448). Moderate offshore breeze from the N. It’s a good day for a beginner-friendly wave, though it might be a little raw for the true groms.

Now we hit a bit of a dry spell. Wednesday the 16th and Thursday the 17th morning are rough with strong onshore winds. The 16th has a 5 ft S swell but onshore wind kills it. The 17th morning turns glassy again, with a 5 ft S swell, 13-second period, and strong energy (658). That’s a real standout. It’s clean, it’s got push, and no wind. But it’s only a small window.

Friday the 18th through to Tuesday the 22nd is largely poor. The wind is mostly cross-off or offshore but strong (15-19 mph), which will make paddling out a battle. Swell sizes drop from 5 ft down to 0.7 ft. The combined energy falls off a cliff; by the 21st, it’s weak at 12. You’ll be doing more floating than surfing.

Then we get to the real prize. Thursday the 24th of September is the true standout. Morning and afternoon both see 6 ft S swell, 12-13 second period, and glassy conditions. The combined energy is very strong – 1085 in the morning and 1230 in the afternoon. This is heavy water. For experienced surfers only. The swell is solid, the wind is nonexistent, and the period is long. However, it’s a long period S swell, so at a beach break like Geriba, it might break a bit straight or close out. Keep your wits about you.

Friday the 25th holds onto that energy with a 6 ft S swell and a very long period of 14 seconds in the morning (energy 1352). Wind is cross-off from the E, but it’s moderate. The swell is still big – expert territory again. The afternoon drops to 5 ft but the period stays long.

So, to sum it up: the best days are Friday morning the 11th for the smaller, clean, offshore conditions, and Thursday the 24th for the big, glassy, powerful groundswell – but that one’s for the experienced crew only. There’s a decent stretch from the 18th to the 23rd with hardly any surf, so don’t plan a trip around that.

Get your wax ready for the 11th and the 24th. The rest is a waiting game.

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.
