The Lowdown
Alright, let’s see what’s cookin’ for Algarrobo.
First off, the water’s sitting at 57°, which is a touch warmer than usual for this time of year – nothing crazy, but it’s a nice little bonus.
The forecast kicks off with a slow start. Tuesday afternoon and Wednesday morning are a bust – poor surf, messy wind. Not worth the hassle.
Come Friday morning, things start to get interesting. We’ve got a clean 3ft swell from the SW with a 12-second period, and light cross-offshore wind from the SE. That’s a sweet combo for Algarrobo – a reef and pier setup that loves a bit of offshore. The combined energy is moderate (290). It’s a solid session, not a standout, but a good way to ease into the weekend.
The real standout hits Sunday morning, the 13th. This is the one. Glassy conditions, a 2ft swell from the WSW with a very long period of 18 seconds – that’s proper groundswell. Light cross-offshore wind from the SSE. The water will be clean, the waves will have shape, and the tide should be fine. Combined energy is 534, which is moderate but punchy for the size. This is a session for the purist. The long period means it’ll wrap nicely into the point, so don’t expect it to close out. Crowds are sometimes an issue here, but with that clean, glassy morning, it’s worth the company.
The following Sunday morning, the 20th, is another beauty. Glassy again, with a 4ft SW swell at 14 seconds. Combined energy is strong (811). That’s a lot of power for a clean morning. The swell is a bit bigger, so if you’re intermediate or above, you’ll be in for a treat. The offshore wind is a rare gift. This is the second standout of the run.
The last little gem is Wednesday morning, the 23rd. Glassy again, with a 4ft WSW swell but a shorter period of 10 seconds. Combined energy is 610. It’s clean, but the wave quality won’t be as good as the 13th or 20th. Still, a fun session if you’re keen.
Between the 13th and the 20th, expect a lot of choppy afternoons and cross-on winds. The mornings are where it’s at. The swell stays around 3ft to 6ft most days, but the wind is the enemy. If you’re an expert, the 6ft to 7ft afternoons are too messy. Save your energy for those glassy mornings.
So, the two best bets are Sunday the 13th morning and Sunday the 20th morning. First one’s a glassy, long-period groundswell session. The second is a bit bigger, but still clean. Get in the water early.

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.
