The Lowdown
Alright folks, Rusty here. Let's have a look at the surf for Joaquina over the next couple of weeks. It’s a bit of a slow start, but there’s a couple of windows that’ll get the pulse going.
We’re kicking off in a pretty flat and messy state. The water is running a bit cold for this time of year at 64°F, which is noticeable. The first few days are a write-off. Friday and Saturday are full of onshore winds and lumpy, junky surf that just isn't worth suiting up for. Saturday the 12th has a bit more energy with a cross-on breeze, but it's all over the place.
We’ve got a proper lull for several days, with no real recommendations until we get to the middle of next week. You’ll want to keep an eye on Tuesday the 15th. The morning is looking like the first real highlight. The wind goes nearly dead glassy and there’s a clean 4ft of ESE swell pushing in. The energy is moderate, and it's making for some clean lines. That’s your first standout window.
The next good window shapes up for Thursday the 17th. It’s a bit more size at 5ft from the SE, with a proper long-period groundswell of 12 seconds. The energy is strong, too. The wind is light and cross-off early, which should keep the sandbar at Joaquina working. This long-period swell might straighten things out a little, but this spot can handle it when it’s clean. That morning looks like the pick of the bunch.
Things ease off again after that. There’s nothing worth mentioning for the rest of the second week, with mostly onshore breezes and dropping swell. It’s a long way out, so don’t hold me to it, but there might be a pulse of bigger swell on the 23rd and 24th. Wednesday the 23rd has some size at 6ft from the SSE and Thursday the 24th looks even bigger, pushing 7ft with a long 12-second period and strong energy. But the wind is just not on our side for either day, looking cross-shore at best and onshore at worst. That 7ft plus is starting to get into expert territory anyway, especially if the banks are as fickle as they look.
So, for the board you want: keep next Tuesday the 15th morning and Thursday the 17th morning circled on the calendar. They aren’t massive waves, but they’ll be the cleanest and most fun you’ll get in this stretch. Otherwise, it’s a waiting game.
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.
