The Lowdown
Alright folks, this is Rusty. Let's have a look at what's on the menu for Joaquina over the next couple of weeks.
To be honest, the first week and a half is a bit of a write-off. We’ve got a long stretch of grovelly, onshore junk from the 1st right through until the 11th of September. Winds are mostly cross-on or cross-onshore, and the swell is all over the shop – small, short-period, and messy. The wave energy is weak for most of that, barely cracking 100 (82–94), and the water is sitting at 66° with a tiny anomaly, so it’s about average for the time of year. You’ll be paddling your guts out for nothing. There’s a brief spike of stronger energy (around 509 and 488) on the 2nd, but the wind is still cross-on, so it’s more of a frustrating tease than anything rideable. Honestly, it’s a rough start.
But hold on. The one true standout, the one that makes this whole outlook worth reading, is coming up on Monday the 7th of September. The morning session is looking like a gem. The swell is a solid 7 ft from the S, with a period of 10 seconds, and combined energy is a heavy 1329 – that’s proper juice. The wind is a gentle cross-shore, which will keep the face clean. Now, that’s a serious wave. It might be a bit much for the beginners, but for the experienced crew, that’s a session to block out for. The only caveat is that the report says the swell might be too big for this break, so it’ll be a heavy, powerful one. Don’t expect it to be easy.
After that, things settle back down into mediocrity. The 8th through the 11th is more of the same – poor conditions or marginal surf. You’ll see a bit of a pulse again on the 13th, with a 6 ft swell from the S and glassy conditions on the Sunday morning. That’s a nice little window, with clean waves and a combined energy of 708. That’s your second best bet, but it’s a far cry from the 7th.
The middle of the second week (14th–16th) is back to lumpy, choppy, and onshore. Not much to get excited about.
So, there you have it. The first week is a bust. The 7th of September morning is the one to circle. The 13th morning is a decent backup. Other than that, you’re better off waiting for the next swell window.
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.
