The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up for Joaquina.

Right off the bat, the first few days are a bit of a write-off. Saturday the 22nd and Sunday the 23rd are pretty average – onshore crud and small, messy waves. You’re not missing much. We’ve got about a two-day gap before anything really worth talking about.

The real standout for this whole outlook lands on Monday the 24th. That morning is looking prime. We’ve got a solid 6 ft groundswell pushing in from the SSE, with a very long period of 15 seconds. That’s proper energy, and the combined swell energy is a beefy 1589. The wind is glassy – dead calm – so the surface will be like a mirror. This is excellent surf, but those waves are going to have some punch. With the size and period, this is really for experienced surfers only. The long period means the sets will be well-spaced, making it easier to get out the back, but at a beach break like Joaquina, that long period can make the waves a bit too straight and fast. Crowds are likely here, so get in early.

The action carries on into Tuesday the 25th morning. The swell drops to 4 ft from the SSE, still with a decent 13-second period, but the wind is light offshore from the NNW. That’s clean, lined-up waves, and the energy is moderate at 512. The water temperature is about 67°, which is right on the money for this time of year.

Wednesday the 26th is another solid day. The swell shifts more SE, with 6 ft and a 15-second period, and the energy is strong at 1297. We’re getting a light cross-offshore breeze from the north, keeping the waves clean and well-shaped. Again, this is powerful stuff for the experienced crew.

After that, the swell fades out considerably through the end of August, dropping to small, weak waves by the 28th. There’s a bit of a lull, but it’s not all bad. Looking ahead to the start of September, there’s a promising window on Tuesday the 1st of September. The swell is only 5 ft, but it’s from the ESE with a short period of 7 seconds. The wind is glassy – dead calm – which makes for a beautiful, clean surface. The energy is moderate at 402. This is a good option for the intermediate crew, but the short period means the waves will be a bit weaker and more crumbly. It’s not a massive standout, but it’s a fun, clean session.

The rest of the first week of September is a mix of small, clean conditions and some onshore trash. Nothing that screams “drop everything,” but the clean mornings with offshore winds on the 3rd and 4th are worth a look if you’re desperate.

Overall, the best on offer is the Monday the 24th morning session – that’s the one to circle on the calendar. The Tuesday the 1st of September is a solid second choice for a glassy, smaller-wave day.

Rusty out.

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.
