The Lowdown
Alright, Rusty here, let's break down what's coming at El Estero.
We got a solid run of surf on the way, but the wind's gonna make you work for the good ones. The water's sitting at about 86°, which is a bit toastier than usual for this time of year.
The action fires up this Saturday, August 29th morning. Swell's around 5ft from the SW with a real long period of 16 seconds, packing a ton of energy (1123). It's a bit bumpy with a moderate cross-offshore breeze, so not perfect, but there's plenty of grunt. The afternoon cleans up nicely with a lighter ESE breeze, and the swell bumps up just a touch to 5ft, cranking the energy right up (1374). This is the pick of the first weekend for experienced surfers.
Sunday the 30th sees the swell ease a bit to 5ft and the period drops to 14 seconds. Morning is okay, but by the afternoon a southerly wind change messes things up with cross-shore chop. That one's a write-off.
Monday the 31st through to Tuesday the 1st of September mornings are the dark horse here. The swell drops to 4ft and then 3ft, but we get clean, glassy conditions on Tuesday morning with a light SE breeze. It won't be big, but it'll be fun and clean for a cruisy session.
Wednesday the 2nd morning is a real standout for the patient crew. The swell drops right down to 2ft, but it's got a very long 18-second period and glassy conditions. The energy is moderate (538), but that long period will make for some beautifully shaped, peeling waves at this river mouth. It's a morning for the longboard or a fish.
The next big pulse comes through on Friday the 4th of September morning. We see a return to 5ft swell from the SW, with a period of 17 seconds and massive energy (1456). The wind is light and cross-off, making for excellent conditions. This is the main event for the more experienced surfer – get out there early before the afternoon sea breeze ruins it.
Saturday the 5th morning is even bigger, with 6ft swell from the SW (1580 energy) and light cross-off winds. This is getting up there in size, so it's for the experts only. It's a powerful, long-period groundswell that will be breaking a bit straight at a beach setup, but the river mouth should handle it.
After that, the surf slowly winds down. Sunday the 6th to Wednesday the 9th mornings all offer clean, offshore conditions with swell holding between 3ft and 5ft. The energy stays moderate (518 to 939). These are your consistent, clean morning windows for a solid session.
Thursday the 10th and Friday the 11th mornings are also looking good with 4ft swell and clean offshore winds. The energy picks up again (750 and 830).
The final call is Sunday the 13th of September morning. The swell bottoms out at just 2ft, but it's got a very long 19-second period and is absolutely glassy. Don't expect power, but for a glassy, small-wave trim, it'll be a beautiful way to finish the forecast.
Overall, the standout is the morning of Friday, September 4th for the combination of solid size, long period, and light winds. For clean small-wave fun, the mornings of September 2nd and September 13th are the ones.
Rusty, out.

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.
