The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s on the menu for the next couple of weeks at El Estero.

First up, the water temp is sitting at a warm 86°, which is a touch warmer than normal for this time of year – that’s a nice little bonus. The vibe for the first few days is a bit of a mixed bag. We’ve got some solid, long-period groundswell rolling in from the SW, with a seriously juicy 1132 combined energy reading on Friday afternoon. That’s a lot of power in the water, with waves around 4ft and a period of 18 seconds. That long period means the sets will be fat, clean, and have some proper push, but it also means it’ll be a bit shifty on the beach. This is a river break, so the long-period swell should wrap in nicely. The wind is a moderate offshore from the ENE, so it’s going to be clean. That’s your best bet for the first week, but it’s not a total standout due to the size and tricky nature of the swell.

Saturday morning bumps up to 5ft, but the wind goes cross-offshore and picks up to 18 mph, which will put a bit of chop on the face. The energy drops a touch to 1113, but it’s still solid. It’s more of a grunty, blown-out day for experienced surfers only. The rest of the week into early next week is a slow fade. The swell drops to 4ft by Monday, with lighter winds, and the energy falls into the 400-500 range. It’s surfable, but nothing to write home about.

There’s a notable gap from the 18th afternoon through the 21st where the wind turns onshore or cross-onshore, and the quality tanks. You’ll see a few morning windows with clean conditions and offshore breezes, but the swell is small and weak. The real stand-out, if you’re patient, is the very end of the run. On Friday the 28th morning, we see a clean, gentle offshore breeze from the E with a 3ft SW swell and a 16-second period. The energy is back up to 448. Then Saturday the 29th morning is the real gem: 4ft from the SW, 16 seconds, light ENE offshore wind, and the energy jumps to 836. That’s the most promising window of the entire forecast. It’s a week and a half away, so keep an eye on it, but as things stand, that’s your best call.

Overall, the first week is for the experienced crew who want to grapple with a powerful, long-period swell. The second week has a few small, clean windows, but the real highlight is that final weekend. If you can wait, do 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.
