Alright, surfers, Rusty here. Let’s have a look at what’s shaping up for El Estero over the next couple of weeks.
Straight off the bat, Thursday afternoon is a bit of a write-off with a marginal call, but we’ve got a long run of clean, rideable waves coming our way. The water is a touch warmer than normal for this time of year, sitting at 86°, so you’ll be comfortable in a spring suit or just boardshorts.
The real story starts Friday morning, July 10th. We’ve got a consistent 3ft SSW groundswell rolling in with a nice long 15-second period, and the wind is a clean cross-off. It’s not huge, but it’s got that long period energy that makes for a proper, lined-up wave. The combined energy is moderate (419). Friday afternoon gets even better – the wind goes dead calm, glassy conditions, and the swell drops just a touch to 3ft but that glass makes it a dream. This is a standout window for the patient surfer.
Saturday morning, July 11th, is another glassy session with 3ft SSW swell, 15-second period, and a light easterly breeze. It’s clean, it’s consistent, and it’s going to be fun. The afternoons get a bit tricky with onshore winds, so make the most of the mornings.
The consistency holds through Sunday and Monday. Sunday morning, July 12th, has 3ft SW swell and a cross-off breeze, just clean and easy. The wave energy is moderate (333). Monday morning, July 13th, is a little smaller at 2ft, but still clean and surfable.
We hit a bit of a lull Monday afternoon into Tuesday morning, but Tuesday afternoon, July 14th, is a sneaky good one. The wind goes glass again, and the swell jumps a little to 2ft from the SSW with a 14-second period. The combined energy is strong (499). That’s a proper session if you can get out.
The pattern continues through the week. Wednesday morning, July 15th, has a moderate offshore breeze with 2ft SSW swell, and Thursday morning, July 16th, is gentle offshore and clean with 2ft SW swell. The real standout in the second week is Tuesday, July 21st. Tuesday morning brings a solid 8ft SSW swell, but it’s short-period at 9 seconds. That’s a lot of power (1896 combined energy) and it’s offshore, so it’s going to be big and heavy. This is strictly for experienced surfers only. The afternoon turns ugly with a cross-onshore wind, so get it early.
The last few days of the window, from July 22nd to the 24th, see a drop back to smaller, cleaner waves. Friday morning, July 24th, has a nice 4ft W swell with a clean cross-off wind, a good way to finish the run.
Keep in mind, El Estero can get crowded, and it’s often busy, so expect company. The long period groundswells here are best when there’s a bit of bank, but the river mouth setup can handle it.

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.
