The Lowdown

Alright, Rusty here. Let's talk about what we've got cookin' at Joaquina over the next couple of weeks.

Right now, the water's sittin' at 64°, which is a bit colder than normal for this time of year – you'll feel that difference for sure.

Honestly, the next few days are a bit of a write-off. We've got some small, weak swell comin' in from the SSE, mostly around the 3ft mark, but the wind's all wrong. It's blowin' cross-on or cross, and that's just makin' a mess of things. The wave energy is weak to moderate (162), and it's just not offerin' anything worth paddlin' out for.

There's a bit of a wait, but things start to look up around Thursday the 17th. The swell picks up a little, still from the SSE, but the real story is the wind. On Thursday morning, it goes glassy – dead calm – and that's a game-changer. The swell's around 4ft with a period of 10 seconds, and the energy is moderate (259). That morning session is the first real standout we've got. The afternoon looks clean too, with a light cross-off breeze from the NNE. That's your window if you can sneak out.

Friday the 18th is still rideable with the same offshore wind, but the swell drops a bit to 2ft. It's surfable, but nothin' to write home about.

Then we hit a dry spell. From Saturday the 19th right through to Monday the 21st, it's tiny. We're talkin' knee-high dribble, if that. The wave energy drops to almost nothin' (9). It's a proper flat spell.

Now, hold onto your board, because things get interesting again on Tuesday the 22nd. The morning looks glassy again, with a 4ft swell from the east and a period of 9 seconds. The energy is moderate (241), and with those conditions, it could be really fun. That's another standout, but the wind changes in the afternoon, so get on it early.

Wednesday the 23rd is a write-off again with onshore wind, but then we get another shot on Thursday the 24th. Glassy in the mornin' with a 3ft easterly swell, and then the afternoon cleans up nicely with a 4ft swell from the ESE and a light cross-off breeze. That afternoon session looks like a solid choice.

The swell gets a bit longer period on Friday the 25th, but it's too small at 1ft, so don't get your hopes up. Saturday the 26th morning, however, is glassy again with a 4ft easterly swell – another good call if you can make it. After that, it's back to onshore slop for the rest of the period.

To wrap it up, if you're lookin' for the best of the bunch, the standout windows are Thursday the 17th mornin', Tuesday the 22nd mornin', and Thursday the 24th afternoon. The rest is a waitin' game.

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.
