The Lowdown
Alright, this is Rusty, and I'm looking straight at the ocean for you.
The wind is gonna be a bit of a factor for a while, but we do have a couple of moments that'll get the blood pumping. Overall, it's a run of mixed conditions, so you gotta be patient and pick your window.
We kick things off this Friday, 4th September. La Boca Con Con is seeing a clean 4ft swell from the WSW with a proper 13-second period. The energy's sitting at a moderate 948. Winds are cross-off, so the face should be pretty clean. This is your best early call, but it's only morning. Afternoon gets a bump in size to 7ft, but the wind picks up to 16 mph and the period drops to a choppy 8 seconds - that's messy, not a good look.
Saturday the 5th has a bigger swell. The morning is a solid 6ft from the SW, energy jumping to 1199, but it’s cross-shore wind. It’s gonna be bumpy. The afternoon drops to a smaller 3ft but the period stretches out to a very long 18 seconds. That's proper groundswell, but it can make a beach break close out. The 1315 energy reading is the strongest of the whole run. Worth a look if you're experienced and like long walls, but the wind is light cross, so it's not perfect.
Sunday and Monday, the 6th and 7th, see lighter winds but they are cross-onshore with a consistent 5ft SW swell and 14-second period. It's surfable, but not special; energy stays between 725 and 962.
Then, a real standout moment. Wednesday the 9th. The morning is glassy. Zero wind. A clean 3ft from the SW with a nice 14-second period, but low energy at 407. This is the session for the longboard or fish. The water temp is about average for the time of year. If you want a clean, easy morning, this is it. Thursday the 10th is similar but smaller, around 3ft, with cross-off winds.
We get another pulse on Friday the 11th. A solid 7-8ft SW groundswell, long 11-12 second period, and cross-off winds. Energy jumps to 1091 then 1280. That's a solid, powerful swell, but anything over 5ft is getting chunky for groms. At 8ft, it's for experienced crew only. The cross-off wind should keep the takeoff zone clean, which is a major positive.
After that, it gets a bit scrappy through the second week. The 12th and 13th have dropping, weaker swell with cross-onshore and choppy winds. Monday the 14th has an offshore breeze for the morning but a tiny 3ft NW wind swell, so it's a small clean session.
Tuesday the 15th brings clean cross-off winds again with a small 4ft WSW groundswell (13 seconds). Energy is at 406. Very similar to the 10th. Good for cruising, not for shredding.
The 16th and 17th are small and poor. The 18th has a final push of 5ft from the WSW with 10-second period and a moderate breeze, but the energy is only 517. From the 19th onward, it drops right off into flatness.
So, the two calls are: the glassy morning on the 9th for the cleanest, most relaxing surf, and the solid, powerful swell on the 11th for the bigger, more demanding waves. Everything else is a gamble with the wind.
Rusty, out.

Information about the La Boca Con Con Surf forecast
The above surf forecast table for La Boca Con Con provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at La Boca Con Con can be found by selecting the local surf guide option on the grey menu.

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 La Boca Con Con 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.
