The Lowdown

Alright folks, Rusty here. Let’s have a proper look at the next couple of weeks for Algarrobo.

Right off the bat, the first week is pretty grim. We’ve got a run of poor to marginal conditions that kicks off Sunday the 16th and just won’t let up. The surf is there, but the wind is a constant issue – mostly cross or cross-onshore from the south, and that’s messing up what could be decent 3ft to 5ft swells. The wave energy stays moderate, topping out around 963 on Tuesday the 18th, but it’s choppy and messy. Not worth paddling out for.

Things finally turn mid-week. Wednesday the 19th morning is the first real standout. The swell bumps up to a clean 6ft from the WSW, with a long 15-second period. The wind goes light and cross-offshore from the north, which should leave it clean. Wave energy is strong at over 1700. It’s going to be a bit too much for beginners at that size, but for the experienced crew, this is the session to target. The water temp is sitting at a pretty standard 57°F, so nothing unusual for this time of year.

Then we hit another dead zone. From Thursday the 20th right through to Sunday the 23rd, it’s a brutal run of poor surf. The swell is still there, but it’s battered by onshore winds. Even Tuesday the 25th sees clean winds but the swell drops right down to 2ft to 3ft – small and marginal, though the 15-second period shows energy in the water.

We get a little glimmer on Wednesday the 26th afternoon. The swell is a small 3ft from the WSW, but with a glassy wind from the NE and a solid 14-second period, it’s clean and tempting for a longboard on the low tide.

But the real payoff is at the very end. Saturday the 30th morning is a beauty – glassy conditions, 8ft of WSW swell, strong wave energy over 2400, and a 12-second period. That’s a solid pulse for experienced surfers. Then Sunday the 31st builds into a proper big-wave event. The morning hits 10ft and by the afternoon we’re looking at 12ft from the WSW with a very long 16-second period. That’s expert-only territory, but with clean offshore wind from the north, it is going to be a serious spectacle. Just keep in mind, at this size and with that period, it might wall up a bit at a beach setup, but Algarrobo can handle it.

To sum it up: the first week is mostly a write-off. Wednesday the 19th morning is your first real chance for a clean, solid wave. And if you’ve got the skills, the weekend of the 30th and 31st of August is where it’s at. Get ready.

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.

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.
