The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Joaquina over the next couple of weeks.
We’re in for a bit of a flat spell to start, but there’s a real gem waiting for us down the line if we’re patient. The water’s sitting at 64°, which is a bit colder than you’d normally expect for this time of year, so you might want an extra layer.
The first real chance of a wave comes on Thursday the 23rd of July, but to be honest, it’s a mess. Swell jumps up to 6ft from the S with a short 8-second period, and the wind is a cross-onshore. The energy is moderate (674), but the conditions are choppy and poor. By the afternoon, the swell hits 7ft from the S, and the energy is strong (1112), but the wind is still cross-on. This one’s just too big and messy for a fun paddle – it’s more of a kite-surfing setup than a proper surf session.
Friday the 24th of July is where it starts to get interesting. The swell drops to a clean 4ft from the SE with a 9-second period, and the wind goes glassy. That’s a beautiful thing. The energy is moderate (298), and the waves will be clean and fun. This is a solid option for a relaxed session, and with the wind so light, it’ll be a joy out there. Saturday morning the 25th holds up with 4ft from the ESE and a clean cross-off breeze, but the rain might put a damper on it.
Now, the standout. You’ve got to circle Wednesday the 5th of August. The morning brings a long-period groundswell from the SSE at 3ft, with a period of 14 seconds. That’s proper energy, and the combined energy is strong (666). The wind is a clean cross-off from the NNW, so the faces will be clean. This is a long-period swell, which means it’ll have more power and shape, but it can be a bit straight at a beach break. Still, for a point or reef setup like Joaquina, this is the best we’re gonna see. The afternoon fades a bit, so get it while it’s good.
There’s a long dry spell after the 25th of July through to the 4th of August, with only tiny, weak, or ordinary waves on offer. It’s a real test of patience. But that Wednesday morning makes it all worth it.
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.
