The Lowdown

G’day, I’m Rusty. Let’s talk about what’s on offer at Algarrobo over the next couple of weeks. It’s a slow start, but there are a couple of sessions that’ll get the blood pumping if you time it right. The water temp here is sittin’ around 57°, which is pretty much spot on for this time of year, so nothing out of the ordinary there.

Right now, and for the first few days, it’s a bit of a write-off. The 11th and 12th throw up some messy, cross-onshore wind and fairly weak to moderate energy (467–418 energy). Swell’s around 4ft to 6ft, but with that wind, it’s just choppy and poor. You can pretty much write off Friday and Saturday.

Come Sunday the 13th morning, that’s where it starts getting interesting. Glassy conditions with a sweet WSW groundswell at 2ft, but the period’s a long 18 seconds. The combined energy is pushing moderate-to-strong at 562. That’s a clean little window with a very long-period groundswell, which can sometimes make beach breaks a bit too straight, but Algarrobo’s reef setup should handle it nicely. The water’s glassy, the wind is nearly nothing, and it’s a morning mission worth setting the alarm for.

The standout, though, has got to be Tuesday the 15th morning. That’s the session I’m most excited about. We’ve got a clean WSW swell at 4ft with a 13-second period, light cross-offshore wind, and a combined energy of 515. It’s not pumping massive, but the quality’s there—clean waves, good shape, and the reef will line it up. That’s your best bet for a solid paddle without battling the crowd. Crowds can show up sometimes, but with a Tuesday morning, you might get a few friendly faces only.

Sunday the 13th afternoon is also worth a mention: offshore wind with a 3ft, 17-second groundswell, and a much higher 676 energy. It’s a bit smaller but the period’s still long, and with that wind straight off the land, the waves will be peeling nicely at Algarrobo’s reef. If the morning window doesn’t suit you, that afternoon glass-off could be a nice consolation.

After that, the middle of the week gets messy again with cross-onshore winds and a lot of poor conditions. There’s a decent-sized 6ft swell on the 19th, but it’s short-period (9 seconds) and blown out—probably more fun for kites than paddle boards. The 22nd and 23rd see similar cross-onshore mess with moderate energy.

The real long-range teaser comes on Thursday the 25th morning. Glassy conditions again with a 4ft, 10-second WSW swell and 379 energy. It’s not huge, but with the wind dead flat and a solid groundswell filling in, Algarrobo should be clean. That’s a solid option if you can wait.

Overall, keep your eye on Sunday morning the 13th and Tuesday morning the 15th for the cleanest waves. The rest of the two weeks is mostly so-so, but there’s enough good windows to keep the stoke alive.

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.

Algarrobo is 21 km (13 miles) from the city of Valparaiso. If you plan a holiday in Santiago, look for hotels and other accommodation in Valparaiso. Valparaiso has rooms for a wide range of budgets as well as car hire and transport links.
