The Lowdown
Alright, let’s get into it.
First off, it’s been a bit quiet out there, but don't let that fool you. The upcoming stretch has some real potential, especially if you’re willing to wait for the right windows. The water’s running about a touch warmer than usual for this time of year, which is always a nice bonus when you’re sitting in the line-up.
We start things off with a bit of a lull. The early part of the forecast, from Friday the 21st through most of next week, is looking pretty lackluster. There’s surf on offer, but it’s small and the conditions are messy, with a lot of cross and onshore wind messing things up. It’s not a total write-off, but you’d be scratching for a half-decent wave.
The first real glimmer of hope shows up on Saturday morning the 29th. The swell has bumped up to about 5ft from the SW, and with light cross-offshore winds, it’s looking clean and lined up. The energy is building, too, with combined wave energy hitting 1173, which is the first time we’re seeing anything with some push behind it. This is shaping up to be one of the better windows.
Sunday the 30th is another good shout. Again, we’ve got a solid SW swell in the 5ft range. The morning is looking clean with that same light cross-off breeze, and while the energy drops a touch to 918, it’s still got enough grunt to be fun. The afternoon cleans up even more, going to just over 5ft and glassy, so if you can sneak out then, you might have it to yourself.
After that, the week ahead keeps the swell running. Monday the 31st has a smaller but still fun 4ft SW swell with clean offshore winds in the morning. Then Tuesday moves through a more inconsistent, average patch.
The next real standout is in the second week. We’re looking at Saturday the 5th of September as a prime target. The swell is up to about 4.5ft from the SW, the winds are expected to be glassy in the morning, and the energy is pushing over 1000. This one has the makings of a proper session. Just remember, it’s a week and a half out, so treat it as promising but not locked in.
Overall, the pick of the period is the Saturday the 29th morning session, with the Sunday the 5th as a solid backup plan. For you beginners out there, that 5ft plus swell is going to be a bit much. This is more for the experienced crew looking for a proper wave. And if you see a bigger day with wind blowing onshore, the beach breaks here are gonna be a mess—more for the kites than the paddle.
Alright, that’s the look. Stay stoked.

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