The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.

We’re kicking things off at El Estero, a river mouth that’s exposed to the WNW. Right now, the water temp is about average for the time of year, nothing weird going on. The forecast starts with a bit of a quiet spell, but don’t write it off just yet.

Sunday the 19th is a bit of a slow starter with 2ft swell from the SW, but the real story is the long period – 19 seconds – and a clean cross-off wind. The energy is moderate (217), so you’ll get some nice, lined-up waves, but the sets will be few and far between. It’s a mellow day for a paddle.

Monday morning the 20th sees the swell bump up to 2.5ft with a 16-second period, but that ENE wind is gusting to 15 mph and it’s cross-off, so it’s a bit messy. The energy is ticking up (366), but it’s not the best. The afternoon is a wash with a risk of thunderstorms and only marginal conditions.

Now, Tuesday the 21st is where it starts to get interesting. The morning has 2.5ft of SW swell with a 15-second period, and we get a lovely offshore wind from the ENE. The energy is solid (539), and the wave comment says it all: expect very good surf. The afternoon gets even better – glassy conditions with a 2.5ft swell and a light NE breeze at 3 mph. That’s a standout window for sure.

Wednesday the 22nd is a mixed bag. The morning is clean but pretty ordinary with 2ft swell and weak energy (173). The afternoon glass-off again with 2ft swell and a bit more energy (285), so it’s worth a look if you’re flexible.

The 23rd and 24th are a bit of a lull. Thursday the 23rd has poor conditions in the morning and a short, weak 8-second period in the afternoon (51 energy). Friday the 24th, however, is a real tease. The morning has 2.5ft swell but a *very long* 24-second period and a massive jump in energy (967). That’s a lot of power, but with that period it’s going to be straight and fast at a river mouth – better for a point or reef. The wind is decent though, so it could be a session for the experienced.

Saturday the 25th is another standout. The morning has 3ft swell from the SW with a 21-second period, and the wind is light offshore from the ENE. Energy is pumping at 975. The afternoon is even better – glassy calm, 3ft swell, 20-second period, energy at 753. That’s a beautiful day for a smooth, clean surf.

Sunday the 26th rolls in with 3.5ft in the morning and a light offshore wind, energy at 938. The afternoon is a real gem: 4ft of swell, 18-second period, and glassy conditions. The energy hits 1007 – that’s strong wave energy – and the report says it’s excellent for experienced surfers. This is a top pick.

Monday the 27th has the biggest energy of the forecast so far. Morning sees 4ft swell with a 16-second period and a clean offshore E wind, energy at 1467. The afternoon is a little tricky with onshore wind, but the morning is a solid winner.

Now, for the second week, things get serious. Tuesday the 28th morning has 6ft of SW swell – that’s getting big, and it’s only for experts. The period is 17 seconds, and energy is a massive 1884. The wind is cross-off and light, so it’ll be clean but powerful. Wednesday the 29th holds at 5ft with similar energy, but the wind is good in the morning. Thursday the 30th is a bit smaller at 4.5ft, with cross-off winds and good energy (793-772).

Friday the 31st drops to 4ft, still with a decent 13-second period, and the morning is clean but a bit windy. The afternoon has a light offshore breeze. Saturday the 1st of August is a bit of a drop-off with 2ft swell, but the afternoon has a nice offshore wind. Sunday the 2nd picks up again to 3.5ft with a moderate offshore wind in the morning, energy at 648. Monday the 3rd finishes the run with 4ft, a 14-second period, and light cross-off winds.

Crowds: El Estero gets crowded often, so on the standout days – especially that glassy Saturday the 25th and Monday the 27th morning – expect company. But it’s worth it.

The best of the best: If I had to pick, I’d say Saturday the 25th afternoon (glassy, 3ft, 20-second period, 753 energy) and Monday the 27th morning (4ft, 16-second period, clean offshore, 1467 energy) are the true standouts. For the second week, Tuesday the 28th morning is a big, powerful session for the experts only.

Get out there and grab some.

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.
