The Lowdown
Alright, mates, Rusty here. Let's have a look at the waves for Algarrobo for the next couple of weeks.
The start of this run is a bit of a letdown, to be honest. The surf is on offer, but it’s poor. For Friday, we’ve got a 3ft SW swell but the wind is cross-onshore and it’s choppy, so the water’s a mess. The energy is weak, sitting at 486, and it’s just not worth paddling out for. We’re looking at a couple of days of this, with Saturday seeing a jump in size to 10ft, but the wind stays on it, making it a cross-onshore mess. That’s a lot of water moving around with 3413 energy, but it’s not going to be any good for a paddle. Sunday is similar, with 8ft to 8ft groundswell, but again, the onshore breeze is going to ruin any chance of a clean wave.
The middle of next week shows a bit of a drop in size, but the quality is still questionable. Monday the 10th has 7ft dropping to 6ft, and the wind is light, but it's still cross-onshore, leaving things a bit rippled. The energy is moderate at 1459. We’re in a holding pattern of average, lackluster conditions.
Now, the one true standout in this whole stretch is Saturday afternoon, the 15th of August. The swell is a clean 5ft from the W with a period of 12 seconds. The wind is cross-offshore, and the forecast says "clean." That’s the window. That’s the moment. The energy is still moderate at 788, but those conditions are going to make Algarrobo look like a different break. It won't be huge, but it will be clean and fun.
After that, we go into a bit of a lull for a week. The swell stays small and the wind is mostly cross or cross-on, keeping things marginal. There’s a pulse of energy showing for the 19th with 8ft from the WSW, but it’s still looking a bit messy.
Then, on Saturday the 22nd of August, we see the biggest swell of the period. It's a 10ft SW groundswell with 4174 energy. This is a serious amount of water. But, it comes with moderate cross-onshore winds. This is a big, powerful swell for experts only. For everyone else, it’s going to be a washing machine. It’s a long way out, so we’ll see how it shapes up, but it’s something to keep an eye on.
So, if you’ve got to pick your moment, it’s that Saturday afternoon on the 15th. For the rest of the week, you’re just going to have to be patient.
Rusty, out.

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.
