The Lowdown

G’day, Rusty here. Let’s talk about Joaquina. It’s a sandbar setup, and it’s very consistent, so you can usually find something. The water’s sitting at 67°, which is about normal for this time of year, so no surprises there.

The outlook kicks off on Monday, September 7th, but honestly, don’t bother. It’s a bit of a dud with weak SE swell at 4 feet and a light onshore breeze. The wave energy is moderate at 256, but the vibe is just poor. Tuesday morning, September 8th, is a write-off too—tiny 3 feet swell with a light offshore, but it’s just ordinary. The afternoon doesn’t get much better, with a 2 feet SE swell and a cross-off breeze.

Then, Wednesday morning, September 9th, is where it starts to get interesting. We’ve got a clean 4 feet E swell, and the wind is glassy—dead calm from the NNW. That’s a major positive, and the wave energy is moderate at 249. This is a solid window for a paddle. The afternoon fades into a 2 feet SSE swell with onshore wind, so don’t stick around.

Thursday, September 10th, has some charm. The morning brings a 3 feet E swell with a light cross-off breeze, and the energy is moderate at 244. It’s clean and surfable. The afternoon shows a 2 feet SSE swell with a 15-second period, which is a long-period groundswell, and it’s clean with a cross-off breeze. Energy is moderate at 211. That’s a good slot for a longer session, especially if you can work the tides.

Friday, September 11th, is a fade. The morning has a tiny 1 feet SSE swell, and the afternoon drops to 1 foot, with moderate wind. Not worth the drive. Saturday, September 12th, brings a messy 1 foot swell in the morning, but the afternoon sees a 7 feet SSE swell with strong cross-on wind. The energy jumps to 1234, which is strong, but the wind is howling at 22 mph, making it lumpy. Keep the board in the car.

Sunday, September 13th, is a big one. Morning has a 10 feet S swell, but the wind is cross-on and strong, energy at 4203—very strong—but it’s a mess. The afternoon shows a 10 feet SSE swell with a 12-second period, and the wind is onshore. The forecast says it’s too big for this break, so only experts should even think about it, and even then, it’s a gamble.

Monday, September 14th, is blown out. Tuesday, September 15th, though, is a standout. The morning is clear, with a 4 feet SE swell, 12-second period, and a moderate offshore wind from the WNW. Energy is strong at 1194, and conditions are excellent for experienced surfers. This is the best on offer in the first week. The afternoon is just okay, with a cross-on breeze.

Wednesday, September 16th, the morning is glassy—dead calm wind, 3 feet SE swell, and a 12-second period. Energy is moderate at 586. It’s clean and fun. The afternoon gets a cross-shore breeze, so morning is the call.

After that, the second week gets grim. Thursday, September 17th, through Saturday, September 20th, is mostly cross-on or onshore wind, with weak to moderate swell. The best of that stretch is Saturday afternoon, September 20th, with a tiny 0.7 feet SSE swell—not worth it. Sunday, September 21st, has a 4 feet E swell in the morning with a light cross-off breeze and moderate energy at 281, but it’s raining heavily. The afternoon is similar.

Overall, the standout is Tuesday morning, September 15th, with that 4 feet SE swell, clean offshore wind, and strong energy. For a glassy session, Wednesday morning, September 16th, is also a good pick. The rest of the window is a lot of waiting, and the second week is mostly poo.

Rusty.

Information about the Joaquina Surf forecast

The above surf forecast table for Joaquina provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Joaquina can be found by selecting the local surf guide option on the grey menu. Our Joaquina 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 (Joaquina) 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 Joaquina 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.
