The Lowdown

IMPERIAL UNITS

Hey, Rusty here. Let’s talk about Algarrobo. This is a reef/pier setup that’s very consistent, exposed to the SW, and it handles a solid south-west swell. The water temp is sitting at 57°, which is pretty much what you'd expect for this time of year—nothing unusual.

The standout session is the early one on Saturday morning, the 29th. We’ve got a clean 6 ft WSW groundswell rolling in with a 12-second period, and it’s absolutely glassy—no wind at all. That combined energy reading is 1016, which is solid, punchy stuff. This is excellent for experienced surfers; the size is right up there, but it’s not so big it’s out of control. The swell direction (WSW) matches perfectly with what this break likes (SW), so expect some proper lines peeling down the reef. You’ll want to be on it early because that clean window doesn’t last long.

By Saturday afternoon the wind swings cross-onshore at 9 mph, and the quality drops straight into poor conditions. Sunday morning the 30th offers a little hope—5 ft WSW swell, 11-second period, with a light cross breeze—but it’s marginal. The combined energy drops to 627, and the wind is just enough to mess with the surface. The rest of the first week is a bit of a slog: Monday the 31st has 4 ft swell but moderate cross-onshore winds, Tuesday drops to 3 ft, and Wednesday the 2nd of September brings a longer period (18 seconds) but with a 16 mph S wind ripping across it, making it choppy and basically unsurfable.

There’s a significant gap through the middle of the outlook. From Thursday the 3rd right through to Friday the 11th, conditions are consistently poor or marginal—cross-onshore winds are relentless, mostly from the SSW at 9–19 mph. The swell sticks around between 3 ft and 6 ft, but the wind just ruins it. Saturday the 5th and Sunday the 6th see some long-period SW groundswell (16 seconds) with energy readings in the 800–900 range, which is moderate-strong, but the wind is again cross-onshore. For a beach-less setup like this reef, a long-period swell needs clean wind, and it’s not getting it.

The very end of the window, around Thursday the 10th and Friday the 11th, we see a few glimmers—Thursday morning has a light onshore breeze and a 2 ft SW, but it’s marginal. Friday the 11th afternoon has 5 ft SW swell with a 11-second period, but a 12 mph S cross-onshore kills it. Honestly, after that Saturday morning glass, there’s nothing else that cracks a proper recommendation. The consistent nature of the break means it’ll come right again, but this 16-day run is mostly a write-off for surfing. If you’re desperate, Saturday morning is your only real shot.

Get it while it’s glassy.

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.
