The Lowdown
Righto, let’s have a look at what’s on the cards for Algarrobo. This is a reef and pier setup, very consistent, and it’s exposed to the SW swell. The water’s sitting at 57°, which is pretty much normal for this time of year, so no surprises there.
The week starts off a bit average. Thursday the 30th and Friday the 31st are nothing to write home about – the swell’s there but the wind is a pain, mainly cross-off from the north, and it’s not shaping up well. You’re looking at 3ft to 7ft of W to NW swell, but the period is short, around 9 to 12 seconds, so it’s gonna be a bit messy. The combined swell energy is weak to moderate, with readings around 291 to 1272, but the conditions just aren’t there to make it worthwhile.
Now, Saturday the 1st of August starts to show some promise. The morning brings a 4ft SW swell with a 12-second period, and the wind is a light cross-off from the north at 3 mph. That’s clean surf, and the energy is moderate at 661. It’s a solid option, but the real standout is Sunday the 2nd. Early morning, glassy conditions with the wind dropping to nothing, and a 8ft W swell with an 11-second period. The combined energy jumps right up to 1573, and the surf is excellent for experienced surfers. This is the best on offer in the first week – overhead, clean, and with that long-period energy, it’ll be a proper session. Monday the 3rd isn’t far behind either, with a 7ft WSW swell, 12-second period, and glassy conditions in the afternoon. That’s a cracking day too.
The middle of the week, Tuesday the 4th, sees the wind swing onshore, and the quality drops off. It’s still a decent size, around 6ft to 6ft, but the cross-on wind makes it choppy. Wednesday the 5th is a funny one – the morning is glassy with a 7ft WSW swell and a 14-second period, which is a long period groundswell, so it’ll be powerful and clean at the reef, but the afternoon turns onshore and messy. Thursday the 6th and Friday the 7th are a write-off with strong 16 mph south winds, making it choppy and poor. The swell is still there, over 7ft, but it’s not worth it for paddling out.
The second week gets quiet. From Saturday the 8th through to Thursday the 14th, it’s a long stretch of small surf and poor conditions. The swell drops to under 3ft, the period is short, and the wind stays onshore. The combined energy is weak, often under 500. There’s a small window on Friday the 14th of August morning, where a 2ft W swell with a 16-second period comes in with a light cross-off wind from the SE. That’s a very long-period groundswell, so it’ll be clean but tiny. It’s a session for the log, not the performance board.
Overall, the absolute standout is Sunday the 2nd of August, with the glassy, 8ft to 8ft W swell. Monday the 3rd is a close second. Everything else is a struggle, especially the second week where it’s mostly flat and messy.

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.
