The Lowdown

Alright folks, Rusty here. Let’s have a proper look at what’s coming our way for the next couple of weeks. We’ve only got one spot on the radar, but it’s a good one.

The Outlook

Alright, we’re starting off with a bit of a slow burn, but the waiting pays off. The first proper action kicks off early Monday morning, August 31st, and it’s not a massive day, but it’s a clean one. We’ve got head-high swell, around 4ft, pushing in from the SW with a nice long period of 13 seconds. That’s proper groundswell energy, and with a light cross-offshore breeze from the NE, it’ll be clean. The combined energy is sitting at 454 (moderate), so there’s a bit of grunt behind it. The water temp is about average for the time of year, so nothing unusual there.

The real standout, though, the one you need to circle on the calendar, is the morning of Friday, September 4th. The swell jumps up to a solid 5ft from the SW, with a 17-second period – that’s serious, long-period groundswell. The combined energy hits a massive 1468 (strong), and with a light NE cross-offshore breeze, it’s going to be clean and powerful. This is excellent surf, but that 5ft mark puts it in the zone for experienced surfers only. It’s a bit too much for beginners.

The next morning, Saturday, September 5th, is also a cracker. We’ve got 6ft of SW swell, again with a long 16-second period, and the energy is right up there at 1462 (strong). The wind is glassy, coming from the SSE at just 5 km/h, so it’s going to be absolutely perfect conditions. Again, this is for the experienced crew only – that size is serious.

Looking further ahead, the morning of Thursday, September 10th, is another promising one. The swell is 4ft from the SW, with a 15-second period, and the energy is a solid 1085 (strong). The wind is a clean offshore from the ENE at 15 km/h, so it’s going to be groomed. That’s a nice, solid session for the intermediates and above.

Overall, the mornings are where it’s at. The afternoons almost always get a cross-onshore wind that messes things up, so plan your sessions early. The first week is the most reliable, with the second week looking a bit more fickle but still offering some glimmers. Get on 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.
