The Lowdown
Alright, this is Rusty. Let’s break down the next 16 days at Joaquina.
For the first few days, Wednesday the 9th through Friday the 11th, we’ve got clean conditions thanks to light offshores, but the swell is small and mostly short-period. Wednesday morning will be glassy with 3ft waves from the east, but that period is only 7 seconds, so the energy is moderate (218). It’s rideable but nothing to get too excited about. Thursday and Friday see the swell drop and the wind picks up, so those days are pretty ordinary.
Saturday the 12th and Sunday the 13th, the swell actually bumps up to 5-6ft from the SSE and SE, with combined energies jumping into the 500-600 range. But the wind is strong onshore or cross-on, making it lumpy and messy – honestly, that setup looks more interesting for kite surfing than paddle surfing.
Then we hit a pretty quiet stretch from Monday the 14th through Saturday the 19th. Most days have poor conditions with light or onshore winds and minimal swell. A few mornings might be clean, but the wave heights are tiny – around 1ft to 3ft – and the periods are short. Not worth paddling out for.
Now, the standout window is Thursday the 17th and Friday the 18th. Thursday morning brings a solid 3ft SSE swell with a long period of 13 seconds and ultra-light cross-offshore winds – the energy is strong (439). This is a proper groundswell, and with those conditions, the sandbars should hold some nice lines. It’s going to be very clean and surfable, and with the longer period, paddling out will be easier. Friday morning is also good: 2-3ft from the SSE, 12 seconds, and offshore NNW wind at 6 mph, keeping the faces smooth.
After that, the final week from Sunday the 20th through Tuesday the 22nd has some clean windows but the swell is inconsistent and short-period. A few glassy or offshores mornings could give you a knee-high wave, but it’s marginal. The week finishes flat with tiny, weak energy.
So, overall, Thursday morning the 17th is the pick of the fortnight. Friday morning the 18th is your next best call. The rest is mostly small, messy, or flat.

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.
