The Lowdown
G’day, Rusty here. Bit of a flat, frustrating run ahead for Joaquina. The next week and a half is mostly a write-off, but there’s a sweet little window out the back end of the forecast that might just save the trip.
We’ve got a long, dry spell staring us down. From now all the way through to Monday the 9th of September, it’s pretty much a waste of time. Cross-onshore winds and messy, choppy conditions dominate. There’s a bump on Monday the 2nd with a 5ft SE swell (509 combined energy), but that onshore breeze kills it. Thursday the 3rd looks clean but the swell’s tiny and weak. Friday the 4th and Saturday the 5th are dog food – small, onshore, and choppy. Sunday the 6th and Monday the 7th bring a bit more size, but the wind is still cross-on, and Monday morning’s 8ft S swell is actually too big for this sandbar, pushing the wave energy into the very strong range (1506 combined energy). That’s expert only if you’re brave, but the wind’s not helping.
Now, the highlight. Tuesday the 8th of September is a rare gem. Early morning we get glassy conditions with a light WNW breeze, a clean 4ft SE swell (234 combined energy), and the word is "expect good surf conditions." That’s the one to aim for – small but clean, and for Joaquina that’s a score. The water temp is sitting at about 66°F, dead normal for the time of year, nothing weird there.
After that, it’s back to the grind. Wednesday the 9th to Saturday the 12th is crossover junk, onshore slop, or tiny weak waves. Then another flicker appears on Sunday the 13th of September – glassy early with a 5ft SSE swell (440 combined energy) and "expect good surf conditions." Monday the 14th looks even better: a 5ft SSE swell (946 combined energy) with clean NNW offshore breezes, and the call is "expect very good surf conditions." That’s the other standout – real promise there. Tuesday the 15th holds clean, smaller waves with glassy patches, but by Wednesday the 16th the wind swings back onshore and it’s all over.
Bottom line: if you can, hit Tuesday the 8th of September early morning, and keep an eye on Sunday the 13th and Monday the 14th. The rest? Not worth paddling out for.
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.
