The Lowdown
Alright folks, Rusty here with a look at what the next couple of weeks are serving up for Algarrobo. We've got a bit of a slow start, but there's some serious power building on the horizon, so don't write this stretch off just yet.
The first few days are pretty average. Friday the 21st and Saturday the 22nd are a write-off with messy cross-onshore winds chopping up the swell, and the energy just isn't there. Sunday the 23rd is a bit more hopeful with cleaner conditions as a light northerly breeze sets in, but the swell is small at around 3ft, so it's more of a longboard session.
The real standouts hit in the second week. Tuesday the 27th of August is the first day that really gets the heart pumping. The morning is looking at a solid 10ft groundswell from the WSW with a long period of 13 seconds, and by the afternoon the wind goes glassy. That's a recipe for some excellent, powerful waves, but with that size, it's strictly for the experienced crew. The combined energy is a massive 3066, showing the kind of power you'll be dealing with. Water temps are about what you'd expect for this time of year, so no surprises there.
Another date to circle is Wednesday the 3rd of September. Again, we're looking at 10ft of WSW swell, but this time the winds are a light cross-onshore, keeping things just a touch textured. Still, with that kind of energy (3772) and period (14 seconds), it's going to be a big, powerful day at the reef. Thursday the 4th of September still has some nice leftover size around 6ft from the SW with cleaner morning conditions.
For the best of the best, though, you have to focus on that Thursday afternoon the 27th of August. It's 10ft from the WSW (right in the optimum direction for the spot), glassy conditions, and long-period energy. It's going to be a standout session for those who can handle it.
Alright mates, that's the picture from here. Keep an eye on the sky and the tide.
Rusty.

Information about the Algarrobo Surf forecast
The above surf forecast table for Algarrobo provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Algarrobo can be found by selecting the local surf guide option on the grey menu. Our Algarrobo 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 (Algarrobo) 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 Algarrobo 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.
