The Lowdown
G'day, Rusty here, lookin' at the surf ahead for Algarrobo. It's a reef and pier setup, exposed to the swell, and it's a very consistent spot, so you know it's always got some kind of energy.
Right now, things are pretty flat and ordinary. The next couple of days are a write-off with weak, short-period swell and messy winds, so don't bother paddling out until things start to turn around. There's a bit of a wait, but it's worth it.
The first real glimmer of hope hits on Thursday the 27th of August. We've got a serious pulse of energy coming in from the WSW, with a solid 12 ft of swell. This is a long-period groundswell (16 seconds), which means proper, powerful waves. It's big though, definitely expert territory, and the wind is a light cross-onshore, so it'll have a bit of texture. The combined energy is absolutely pumping at 6737, so this is the standout for the big-wave crew. The following day, Friday the 28th, drops a touch to 8 ft from the WSW with a 14-second period, still holding plenty of energy (2329), but it's still a big, powerful wave. For the average punter, that's a bit much, but if you've got the balls, Thursday morning is the call.
Things settle down over the weekend of the 30th and 31st, with the swell dropping to 5 ft. Sunday the 30th afternoon looks the pick with clean, cross-off winds from the NNW, making for a fun, manageable session.
Looking further out, the first week of September looks a bit messy again with strong onshore winds and lumpy conditions. There's a big swell on Thursday the 3rd of September (8 ft, 16-second period), but the cross-onshore wind will chop it up.
But hold on, the real gem in the second week is Saturday the 5th of September. The swell is a super fun 6 ft from the WSW with a 12-second period, and the wind goes glassy. That's the kind of forecast you dream of. The combined energy is still a solid 946, so there's plenty of push, but it's not a monster. Sunday the 6th of September is also looking choice, with 7 ft of WSW swell and glassy conditions in the morning, then clean cross-off winds in the arvo. That Saturday and Sunday are your best bets for a proper, clean, powerful session that won't try to kill you.
Algarrobo is very consistent, so even when it looks grim, it's only a matter of time before the next pulse rolls in.
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.
