The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking for La Boca Con Con over the next couple of weeks. We’ve got a solid run of surf lined up with only a few quiet days, so this is a promising stretch for the area.
Right now, Sunday the 16th is kicking off with a modest 3 ft swell from the WSW at a clean 14-second period. Water temp’s sitting at 57°, which is about average for this time of year. The morning session is the go with that light cross-off breeze keeping things tidy. The combined wave energy is moderate (498). The afternoon gets windier, so it’ll drop off.
Monday the 17th holds a similar 3 ft with the same long-period groundswell; morning is your pick with a light cross-off. The afternoon swings offshore with a WNW breeze, but the surf quality drops right off then – not worth it.
Tuesday the 18th is where it starts to build. We’re seeing 5 ft in the morning climbing to 6 ft by the afternoon, both from the SW around 12 seconds. Wave energy jumps to a strong 932-1274 range, and the wind is a clean cross-off. This is a proper fun day with good shape on offer.
Wednesday the 19th sees the swell peak at 6 ft but the wind turns cross-on, so the surface gets a bit bumpy. Still, there’s some power there. The swell period hits a very long 15 seconds (1578 energy), so stronger paddling and longer waits between sets. This will be for the more experienced crew.
Thursday the 20th morning cleans up beautifully: 6 ft, cross-off, light wind. Really good waves there. The afternoon gets a bit messier with a moderate breeze, but still surfable.
Friday the 21st is a standout morning: 3 ft but with 14-second period and that sweet cross-off wind. Quality over quantity. The afternoon, however, jumps to 8 ft with that same SW swell. That’s expert territory and it gets windy, so the morning is the smarter call for most.
Saturday the 22nd keeps the 6 ft coming with clean morning conditions. The afternoon turns glassy with 6 ft – that is a rare treat, clean and lined-up waves. Mark that one down.
Sunday the 23rd and Monday the 24th are a bit of a write-off as the swell drops and the wind goes all wrong. A few small wind-affected waves but nothing you’d bother with.
From Tuesday the 25th through Wednesday the 26th, we’re in small-wave territory, 2 ft to 3 ft, but Wednesday morning turns glassy – maybe a fun little log if you’re keen, but not a serious session.
Thursday the 27th bumps back up to 4-5 ft but with onshore wind. Not good for paddle surfing – this setup actually looks more interesting for kite surfing than paddle surfing.
Now for the real highlight at the end of this run: Sunday the 30th morning is firing. 6 ft, WSW, 11-second period, light cross-off, and 1608 energy – that’s excellent. Monday the 31st is the absolute best of the lot. Morning brings 7 ft with a 13-second period and an offshore SSE wind. 1594 energy, clean as a whistle. The afternoon glassed off at 7 ft and 2792 energy – that’s powerful, long-period groundswell with glassy conditions. That is for the experienced only, but it’s the top pick of the entire outlook by a long shot.
La Boca Con Con can get crowded – it’s very consistent and reasonably exposed, so expect company on the good days. For beginners, keep to the smaller days under 5 ft like the 16th, 17th, or that small Wednesday the 26th.
So to sum it up: the best of the bunch is Monday the 31st – morning and afternoon are both gold if you know what you’re doing. Second best is the glassy Saturday the 22nd afternoon. Get on it.
Rusty.

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.
