Updates in hr min s Forecast update imminent
Alright, Rusty here. Let’s break down what’s coming up.
We’ve got a slow start, but don’t count it out completely. The first chance to surf is Sunday afternoon, July 5th, but it’s a dud. There’s a risk of thunderstorms, a light onshore breeze, and a weak 3ft swell from the SW with a long 16-second period. The water is 86°, which is a touch warmer than normal. The combined energy is 381 (moderate), and the conditions are poor. Skip it.
Monday the 6th is a mixed bag. The morning is clean with a 2ft SW swell, but the period is a very long 20 seconds. That kind of period can make a river mouth like El Estero (El Estero) run a bit straight. The energy is 770 (moderate). The afternoon has a 3ft SW swell, but the wind is onshore.
Tuesday the 7th is the clear winner. This is the standout. The morning has a clean 4ft SW swell with an 18-second period and a moderate offshore breeze. The energy is 1208 (strong). The afternoon is even better: a 5ft SW swell, light offshore wind, and glassy conditions. The energy hits 1263 (strong). This is excellent surf for experienced surfers. The river mouth will handle that long-period groundswell well. Expect crowds.
Wednesday the 8th is still solid. The morning is clean with a 4ft SSW swell (864 energy), and the afternoon goes glassy with a 4ft SW swell (755 energy).
From Thursday the 9th onward, the swell drops into the 2ft to 3ft range. There are still clean windows. Thursday morning is clean with a 4ft SW swell (544 energy). Friday the 10th afternoon is glassy with a 3ft SW swell (426 energy). Saturday the 11th morning has a gentle offshore and a 3ft SSW swell (375 energy). The second week is a slow grind of small, clean waves. The best of the second week looks like Saturday the 18th afternoon, glassy with a 3ft SSW swell (270 energy), and Sunday the 19th afternoon, also glassy with a 3ft SSW swell (357 energy). The long-range stuff is promising but less certain.
The clear standout is Tuesday the 7th. Don’t miss it.
Rusty.

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.
