The Lowdown

Right then, let’s have a look at what's cooking for us here.

Alright, we’re focusing on Algarrobo for this outlook. The water’s sitting at about 56°F, which is pretty normal for this time of year – nothing out of the ordinary here.

The first few days are a bit of a slow start. Tuesday the 25th has some small 2ft groundswell rolling in from the WSW with a nice, long 15-second period between sets. The wind is a light cross-off, so it’ll be clean. The energy is weak (291), so it’s one for the logs or a longboard, really. You’d be scratching for waves but it’s a nice paddle.

Things properly wake up on Wednesday the 26th. This is your standout. Morning has glassy conditions, a solid 5ft of WSW groundswell with a 12-second period, and the energy is building into the moderate range (714). By the afternoon, it’s pushing 6ft and 895 energy. The wind stays cross-off. This is where you want to be – clean, fun waves.

Thursday the 27th sees the swell jump significantly, hitting 12ft from the WSW with a very long 14-second period. The energy is very strong (5029). However, the wind turns onshore and the quality is marginal. At this size, with that long period, it’s going to be a heavy, straight-closing beast at a beach break. This is strictly for experts and might actually be more interesting for kite surfing than a standard paddle.

Friday the 28th is another good shout, dropping a bit to a still-chunky 8ft. The morning is glassy with strong energy (2321). This is excellent for experienced surfers. That long period (13 seconds) will give it power, but at Algarrobo, watch out for it walling up. After that, the weekend sees the swell easing back into the 5ft to 6ft range with light winds and clean conditions, offering very good surf before a run of poor, choppy conditions kicks in from Monday the 31st.

There’s a bit of a dry spell from that Monday right through to Thursday the 3rd of September, with a lot of onshore wind and choppy seas. The surf picks up again on Thursday the 3rd, with a solid 7ft to 7ft swell from the WSW and a 14-second period, but the cross-on wind keeps things from being perfect. It’s marginal at best. After that, the forecast drops right off again into late next week with poor conditions and strong winds. A classic case of two really good days in the middle, then a lot of waiting.

If you can get on it Wednesday or Friday morning, go. The rest of the window is a write-off.

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.
