The Lowdown
Alright folks, Rusty here. Let's get into it. We've got a solid run of surf on the cards for El Estero, with a great mix of clean conditions and some decent, long-period groundswell.
The water is a touch warmer than normal for this time of year, sitting at 86°F. That's a nice little bonus. This spot is a river mouth, exposed to the west-northwest, and it's a consistent break, so you can usually count on it to have some shape. The best swell direction is from the west-northwest, and for the most part, we're getting exactly that.
The opening session on Wednesday, the 2nd, kicks off with a small but clean 2ft swell from the southwest, with a very long period of 18 seconds. The energy is moderate (538), and with a light cross-offshore breeze from the northeast, it's going to be clean. The afternoon choppes up, so forget that.
Thursday the 3rd is a repeat – morning glass with 2ft, period of 19 seconds, and clean conditions. The energy is ramping up to 731, showing there's some good push coming through. The afternoons are blown out, but the mornings are the clear window.
Now, the real standout is shaping up. Friday the 4th morning is where it's at. We’re looking at a 5ft swell from the southwest with a 17-second period, and the energy is a strong 1425. That's some serious juice. The wind is a light offshore from the northeast, so it's going to be clean. This is excellent for experienced surfers – the size is getting up there, so it's not for the groms. Saturday the 5th morning is also firing, with a 6ft southwest swell and a 16-second period, offering a massive 1578 energy reading and a light offshore wind. This is the best of the whole run. The shape at a river mouth with this long period will be great, with those long, waiting sets. Keep in mind the crowds are likely to be heavy here, as it's a consistent spot.
Sunday the 6th and Monday the 7th still have good morning windows with 5ft and 4ft swells respectively, and the energy stays in the moderate to high range. The afternoons get messy with onshore winds, so stick to the dawn patrol.
The quality dips a little from Tuesday the 8th through to the 10th, but the mornings are still clean with cross-offshore winds. The swell drops to 2ft to 4ft, and the energy falls back to moderate levels. It's still rideable, just not as punchy.
Friday the 11th morning picks up a little again, with a 4ft southwest swell at 16 seconds and 843 energy. Clean conditions. The pattern holds through the weekend of the 12th and 13th – small, clean mornings, blown out afternoons.
The final week, from the 14th to the 17th, is small but clean. The swell is 2ft to 3ft, but the period stays long, between 15 and 18 seconds, so there will be some fun little lines. The energy is on the lower side, but Tuesday the 15th afternoon looks particularly glassy, with a 3ft swell and glassy conditions. A good chance for a sneaky session.
So, the clear winner this stretch is the Saturday the 5th morning session. That 6ft south-west swell with the light offshore wind and massive energy is the pick of the litter. The Friday the 4th morning is a close second.
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.
