The Lowdown
G’day, Rusty here. Let’s have a look at the surf for La Bocana over the next couple of weeks.
The opening stretch is pretty quiet. We’ve got a few small waves on offer from the get-go, but nothing that’s going to get the heart racing just yet. The first few days are all about small, clean morning sessions before the onshores kick in during the arvos. This river mouth setup is going to want a bit more push to really get going.
Saturday the 12th starts things off with a clean 3ft SW swell, but that cross-on breeze will have it a bit lumpy. Not worth rushing out for. Sunday morning drops to 2ft but turns glassy, which will make it look better than it is. Monday holds similar tiny 2ft waves with a glassy start.
The first real standout comes on Tuesday the 15th. The morning glass-off meets a building SSW swell at 4ft, and the combined energy jumps to 926 – that’s moderate, but the clean conditions will make it feel way better. This is the pick of the first week. Wednesday the 16th is right there too, with a 4ft SSW swell and calm winds, energy up to 998. These two mornings are your best bets for a proper paddle.
After that, the swell drops back into the 2ft to 3ft range, with conditions staying clean in the mornings but chopping up with the cross-onshore breeze each afternoon. Thursday the 17th morning has 4ft and zero wind – good, but not as strong as Tuesday or Wednesday. Friday the 18th morning is tiny again at 2ft, but it’s glassy and the period’s a long 20 seconds, which will give it a bit more push. That long period might make it a bit straight at the river mouth, but it’ll still be fun.
The second week keeps a similar rhythm – mornings are clean, afternoons get bumped out. Sunday the 20th morning has a solid 3ft at 19 seconds and glassy conditions, which is your best session of that middle stretch. Monday the 21st is similar. The 23rd sees the swell jump to 5ft mid-week, but the period drops to a short 10 seconds and the wind is onshore – messy and not worth it.
Now, here’s where it gets interesting. The standout of the entire window is hands-down Saturday the 26th of September. The morning brings a 8ft S swell with a 10-second period, calm winds, and the combined wave energy is a very strong 1650. This is proper push – glassy, powerful, and lining up. It’s too big for beginners, and at over 8ft it’s strictly for experienced surfers. The afternoon holds 8ft but the breeze swings onshore, so get on it early.
The very next morning, Sunday the 27th, still has a solid 6ft SW swell at 12 seconds, but the wind turns cross-shore and it gets choppy. There’s still plenty of energy there, but the clean Saturday morning window is the one you want to circle on the calendar.
That Saturday morning is the one. It’s big, clean, and has the most power we’ll see all fortnight. Mark it down as promising, though still a bit far out to be certain. The rest of the time, the dawn patrol is your friend – get out there before the sea breeze ruins the party.
That’s it from me. This river mouth likes a decent SSW swell, and we get a taste of it mid-month, but the real deal is the final Saturday. Don’t sleep on it.
Rusty.

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