The Lowdown
Alright, Rusty here. Let’s get into it.
We’re looking at a solid run of south-west groundswell for La Boca Con Con. The water temp is sitting at 58°, which is about a degree and a half warmer than usual for this time of year, so it’s a touch on the mild side but nothing wild.
The action kicks off Sunday the 9th of August, but it’s a bit of a mixed bag to start. Sunday morning brings a powerful 8ft SW swell with a 13-second period, and the energy is pumping at (3003). The wind is a cross-off from the south at 9 mph, so it’s clean, but the wave comment flags it as marginal – probably a tide or shape issue. That afternoon the swell jumps to 10ft but the wind picks up to 16 mph, making it messy and less appealing.
Monday the 10th is where it starts to come together. Morning session has a 7ft SW swell, 13-second period, and the combined energy is still strong (1569). With a light 6 mph cross-off breeze, it’s clean and punchy – this is a good window for experienced surfers. The afternoon drops a touch to 7ft but stays clean with a gentle breeze. Tuesday the 11th sees the swell ease to 5ft in the morning with a light cross-off, still good shape, but by afternoon the wind picks up and it gets marginal.
We hit a bit of a lull midweek. Wednesday the 12th is glassy but tiny – 1ft to 3ft – with a very long-period WSW swell (19 seconds), so it’ll be clean but weak. Thursday the 13th is a write-off with poor conditions and onshore wind.
Friday the 14th is small and glassy again, 3ft, but the energy is low (262). It’s surfable but nothing to write home about.
Saturday the 15th brings a new pulse: 7ft W swell with 12 seconds, and the energy jumps back up (1354). Winds are light onshore though, so it’s not pristine – good for a paddle if you’re keen, but not the standout.
The best of the bunch looks like Monday the 17th of August. The morning shows 6ft SW swell, 13-second period, with a light cross-off breeze. The combined energy is strong (1086), and the wave comment says “expect very good surf conditions.” This is the one to circle on the calendar – clean, solid, and consistent.
Later in the week, Wednesday the 19th morning is glassy with a 6ft WSW swell, 14 seconds, and energy at (1204). Again, clean conditions and good shape, though the tide might need a look.
From the 21st onward, the swell drops back under 5ft and the winds stay cross-off but lighter. Nothing huge, but plenty of clean, rideable waves through the end of the period. The 24th of August shows a 5ft SW swell with a 14-second period and solid energy (1209), but the wind is cross-onshore, so it’ll be a bit bumpy.
La Boca Con Con is a beginner-friendly spot that’s very consistent, exposed to the swell, and can get crowded sometimes. For the bigger days – like Sunday the 9th’s 10ft – that’s expert-only territory. The 8ft+ days are for experienced surfers only. The longer-period swells (over 11 seconds) will wrap in nicely here, given it’s a fairly exposed beach setup. Keep an eye on those glassy mornings – they’ll be your cleanest windows.
This is Rusty, signing off.

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.
