The Lowdown
Right folks, Rusty here. Let’s talk about what’s coming up for Algarrobo. This reef and pier setup is a very consistent spot, exposed to the swell, and it’s looking like we’ve got a solid run of waves ahead.
The water is sitting at 56°F right now, which is pretty much normal for this time of year—nothing weird going on there.
We kick things off on Wednesday morning, July 29th. It’s cloudy, but the wind is glassy, dead calm out of the SW at just 3 mph. The swell is a clean 4ft from the west with a solid 12-second period. The wave energy is moderate (537). This is the kind of session where you just know it’s going to be good—clean, lined up, and no wind to mess with it. The glassy conditions are a major plus.
Wednesday afternoon holds up too, still glassy, with a 4ft W swell and 11-second period. Energy drops a bit (381), but it’s still good surf.
Now, Thursday the 30th and Friday the 31st are a bit of a write-off. The wind picks up strong from the north, and while there’s some swell around, the conditions are just marginal. The best of the week is going to be the weekend.
Saturday, August 1st, is the real standout. Morning starts cloudy with a light N breeze at 6 mph, giving us cross-off winds and clean conditions. Swell is 6ft from the WSW, 11 seconds, with moderate energy (784). But the afternoon is where it’s at: 5ft SW swell, 12-second period, and the energy jumps to 1020. The wind is a gentle 9 mph from the north, keeping it clean. This is excellent surf for experienced surfers.
Sunday, August 2nd, the afternoon is the pick. The wind goes offshore from the NE at 9 mph, making for a clean, offshore day. The swell is 8ft from the west, 11 seconds, and the energy is strong at 1372. This is a big, powerful wave for the region. It’s going to be a proper session for those who know what they’re doing.
The following week gets a bit messy. Monday the 3rd and Tuesday the 4th have cross-onshore winds and choppy conditions. Not great.
Then we get a pulse of real power mid-week. Wednesday, August 5th, the morning has a 7ft WSW swell with a very long 15-second period. The energy is huge at 1855. The wind is light from the SSE, so it’s cross-shore and clean. This is a long-period groundswell, so it will be better on the reef at Algarrobo than a beach break. It’s a massive wave, though—over 7ft, so it’s experts only.
Thursday the 6th has similar size, 8ft, but the wind is stronger and cross-shore, making it rough. The afternoon is a write-off with 16 mph cross-onshore winds and a choppy mess.
The next weekend, Saturday, August 8th, has a massive 8ft SW swell with a 14-second period and energy of 2603. That’s a lot of power. But the wind is light cross-onshore, so it won’t be perfect. Still, for the brave, there will be some big, raw waves.
The surf fades off after that. By August 11th, we’re down to 3ft, and by the 12th and 13th, it’s essentially flat with poor conditions. The run of good surf lasts about two weeks, with a clear gap of poor conditions from the 12th onward.
So, the best bets: Wednesday morning, July 29th, for pure glassy perfection, and Saturday afternoon, August 1st, for the best all-round swell and clean conditions. If you’re after big, powerful waves, Sunday afternoon, August 2nd, and Wednesday morning, August 5th, are your windows.
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.
