The Lowdown

Alright, Rusty here, let’s talk surf.

We’ve got a slow start, but some real promise if you’re patient. The water’s a mild 57°, just a hair warmer than usual for this time of year.

First chance to paddle out is Thursday the 13th in the morning at Algarrobo. It’s a reef and pier setup, so it holds swell well. You’re looking at a 4ft WSW swell with a 16-second period, which is proper groundswell with some real push. The energy is moderate (760). The wind is light and cross-shore, so it’s a bit rippled but workable for an intermediate. 4ft is a solid height without being too heavy.

Things really clean up on Friday afternoon the 14th. The wind goes cross-offshore, smoothing the surface, and the swell hits 5ft from the WNW. The period drops to 10 seconds, so it’s a bit more local and punchy, and the energy is solid (601). This is a standout for the near term—clean, decent size, and offshore wind is a gift.

Saturday the 15th is similar early, 5ft from the west, but with a risk of thunderstorms later. The wind stays cross-offshore though, so it’s still clean. Just keep an eye on the sky.

Now, the real gem is Wednesday morning the 19th. This is the best on offer. The wind is glassy, total calm, and the swell is 4ft from the WSW with a 16-second period, giving it that long, lined-up energy. The combined energy is strong, reading 1478. This is excellent surf for experienced surfers, and the glassy conditions mean it’ll be a dream. It’s a reef break, so it’ll handle that long period well. Get on it.

After that, the swell drops off and the wind goes onshore from the south, making things choppy and messy for a run. There’s a long gap of poor conditions from the 20th through the 25th, with only small, bumpy waves.

There’s a flicker of hope at the very end of the period. Thursday afternoon the 27th sees a 6ft WSW swell with a 13-second period, and the wind is cross-offshore, keeping it clean. The energy is strong (1094). It’s a decent size, but it’s two weeks out, so treat it as a promising whisper rather than a lock.

Honestly, if you can only surf one day, make it Wednesday the 19th. That’s the one.

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.
