The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Alright, straight up, the news isn't great. The whole 16-day window is looking pretty grim. There’s a bit of swell coming through on September 5th, but it’s not going to be anything to write home about. The wind is just not playing ball. We’ve got a solid run of cross-onshore winds that are going to mess up what little energy we’ve got.
The only spot on the radar is Algarrobo, a reef and pier setup. The water is sitting at 58°F, which is a touch warmer than normal for this time of year.
The first chance to get wet is on Saturday afternoon, September 5th. We’ve got a 3ft SW swell with a very long period of 18 seconds. The combined energy is moderate to strong (1143). The problem is the wind is a moderate cross-onshore at 12 mph, turning it into a choppy mess. This is a classic case of a long-period groundswell that would be better off at a point or reef, but the wind is going to ruin it here.
Sunday morning, September 6th, looks a bit better. The swell picks up to 5ft from the SW, still a very long 15 second period, and the wind goes light and offshore from the W at 6 mph. This is the standout window. It won’t be epic, but it’ll be the cleanest surf of the whole period. The combined energy is still strong (1130). After that, it’s all downhill. The wind stays onshore or cross-onshore for the next two weeks.
From Sunday afternoon onward, the surf is small, chopped up, and just not worth the paddle. The swell hangs around 3ft to 4ft for a few days, but the wind is always there to mess it up. By September 10th, we’re calling it poor, and that’s the story all the way through to the 20th. The wave heights get a bit of a bump around the 16th, hitting 7ft, but that’s with a short 9 second period and a fresh cross-onshore wind. At over 5ft, that’s getting too big for beginners, and with the wind and short period, it’s just a lumpy, messy wall for experts. The energy drops right off by the 18th, with a combined energy of just 152 on the morning of September 18th.
So, to be honest, there’s only one real window here: Sunday morning, September 6th. If you can get out then, you’ll get a clean 5ft SW groundswell with light offshore wind. The rest of the 16 days is a write-off—a long stretch of poor conditions with nothing worth chasing. This is one of those times where the forecast can change, but right now, it’s looking bleak.
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.
