The Lowdown

Alright, let’s get into it. Rusty here, and I’ve got the scoop on Joaquina for the next couple of weeks. This is a sandbar setup, very consistent, and exposed to the south-east. Water temp is sitting at 20°, which is just about normal for this time of year—no surprises there.

We’ve got a bit of a slow start. The first few days are pretty average, with Sunday the 23rd only offering a marginal 4ft swell from the SSE with a cross-on wind. Not worth getting wet for. Monday the 24th shows a bit more size, with a 6ft SSE swell and a 15-second period, but the wind is cross-shore and messy. The wave energy is moderate, but the conditions are just not there.

Now, Tuesday the 25th morning is where it starts to get interesting. The wind swings to a light N cross-off, cleaning up a 4ft SSE swell with a 13-second period. Wave energy is moderate (512), and it’s looking clean. That’s a solid morning session.

But the real standout comes on Wednesday the 26th. Both morning and afternoon are looking excellent for experienced surfers. We’ve got a solid 6ft swell from the SE, with a very long 15-second period—pure groundswell. Combined wave energy is strong (1246), and with a light N cross-off wind all day, the conditions will be clean and punchy. This is the best on offer. Keep in mind that long-period swell like this can break a bit straight at a sandbar, but the size and power will make for some serious waves for those who know what they’re doing.

Thursday the 27th drops off a bit, with smaller 4ft swell and a 13-second period. Still clean but nothing special. Friday the 28th is tiny, with swell dropping to 2ft and weak energy (67). Not worth a paddle.

We hit a real dry spell from Saturday the 29th through to Monday the 1st of September. Swell is small, short-period, and the wind is mostly onshore or cross-on. Choppy and poor. Tuesday the 2nd of September morning throws a massive 10ft swell from the S with a 10-second period and light cross-shore wind, but that’s way too big for this break—really only for the kamikaze crew. The energy is very strong (2422), but it’s a miss for most.

Wednesday the 3rd of September morning sees a nice recovery: a 5ft SE swell with an 11-second period and clean NNW offshore wind. Wave energy is moderate (595), and the conditions should be very good. That’s a promising morning session.

After that, the end of the forecast window tails off into smaller, weaker swells through to the 7th of September. Nothing to get excited about.

So, to wrap it up: the standout is Wednesday the 26th of August with that solid SE groundswell and clean offshore wind. Tuesday the 25th and Wednesday the 3rd of September mornings are solid secondary options. The rest of the period is mostly flat or messy. Crowds at Joaquina can be a factor, especially when it’s good, so get there early if you can.

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.
