The Lowdown

Hey folks, Rusty here. Let’s talk about what’s ahead for Algarrobo. It’s a mixed bag, but there are a couple of moments that’ll get us out of bed.

The coming days are mostly a write-off for quality surf. The wind is a persistent problem, with a cross or cross-onshore breeze and a chop that’ll mess up even the bigger swells. Sunday the 9th kicks off with a solid 8ft SW swell (13 seconds) but that 12 mph southerly crosswind makes it a messy, marginal affair. The combined energy is strong at 2810, but it’s wasted on choppy conditions. Monday and Tuesday stay onshore and choppy, with the swell dropping from 7ft to 4ft. The water here is a touch warmer than normal for this time of year at 58°.

Wednesday morning the 12th is tiny, only 2ft, and still cross-onshore. Not worth paddling out.

Now, Thursday the 13th morning is our first real glimmer of hope. The wind goes glassy, and we’ve got a 4ft WSW groundswell with a very long 16-second period. The combined energy is moderate at 733. The swell direction matches the optimum SW direction pretty well. This is a clean, glassy morning – perfect for a reef/pier setup like Algarrobo. It’s a standout for the first week. Expect some crowd, though, as it’s a spot that can get busy.

Friday the 14th stays small, around 3ft, but with glassy conditions again, it’ll be a fun, clean session for the longboard or a small board.

Saturday the 15th sees a bigger pulse of 7ft W swell (12 seconds), but the wind swings cross-onshore, so it’s back to a messy, marginal look. That’s a shame – the combined energy is a solid 1382.

The second week is where things get interesting. The big standout comes on Wednesday the 19th. We’ve got a 6ft WSW groundswell with a very long 15-second period, and the wind is glassy all day. The combined energy is strong at 1413. This is excellent surf for experienced surfers. The long period will make for clean, powerful lines at the reef, but it can be a bit tricky for beginners – over 5ft and well over 8ft for the experts? No, it’s 6ft, so it’s in that intermediate-to-expert zone. The glassy wind is a major positive. Tuesday afternoon the 18th also offers a clean, cross-off window with a 5ft SW swell, but the 19th is the real prize.

The tail end of the forecast from the 20th onward looks poor again, with onshore winds and choppy, surf. There’s a long gap of poor surf from the 20th through the 24th, with only marginal conditions on Monday the 24th morning.

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.

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.
