The Lowdown

Alright, this is Rusty. Let’s get into it.

We’ve got a solid run of surf coming up at Algarrobo, a reef and pier setup that’s very consistent and handles a SW swell really well. The water is sitting at 57°, which is basically normal for this time of year – nothing weird going on there.

The first real standout is Monday afternoon, August 3rd. The wind is glassy from the east at just 3 mph, and we’ve got a clean 7 ft swell from the WSW with a 12-second period. That’s a proper groundswell with good energy – the combined energy reading is 1241 (moderate) – and it’s going to be absolutely clean. This is for experienced surfers though, as it’s a bit over 5 ft. If you’re comfortable out there, this is the best on offer in the first week.

Tuesday morning, August 4th, is still decent with a 7 ft WSW swell, but the wind goes cross at 6 mph, so it’s not as glassy. Still rideable, but not the peak.

Wednesday, August 5th, has a 7 ft WSW swell with a 13-second period in the afternoon, combined energy of 1683 (moderate), but the wind is from the NNW at 9 mph and cross, so it’s a little messy.

Then we hit a rough patch. From Thursday, August 6th, through to the end of the first week, the wind turns onshore and picks up. Thursday morning is 8 ft but with a 12 mph south wind, cross-onshore and choppy – that’s a no-go. Friday and Saturday are even worse for conditions, with the swell dropping and the wind ruining it.

We get a little breather on Sunday, August 9th, with a 8 ft SW swell and a 16-second period in the afternoon – that’s a very long period groundswell, combined energy at 2890 (strong). But the wind is 9 mph cross-onshore, so it’s lumpy. That’s frustrating because the energy is there, but the wind is killing it.

Monday, August 10th, is a bit better with a 7 ft SW swell and cross wind at 9 mph, but it’s still not clean.

Now, here’s the second standout – and it’s a long-range promise, so keep an eye on it. On Thursday, August 13th, in the morning, we get glassy conditions again, with a 4 ft WSW swell and a 16-second period. That’s a very long period groundswell, and combined energy is 646 (moderate). The wind is calm, glassy. This is going to be clean and fun, but it’s only 4 ft, so it’s for smaller boards. The break is a reef/pier, so that long period will wrap in nicely.

Friday, August 14th, morning also looks good with a 3 ft WSW swell, offshore wind from the NE at 3 mph, and a 14-second period. Small but clean.

After that, from Saturday, August 15th, the swell picks up again but the wind goes onshore, so it’s mostly poor conditions through to the end of the 16-day window. The swell is there, but the wind is ruining it. There’s a gap of about 5 days of poor to marginal surf after the 14th.

So, the best on offer? Monday afternoon, August 3rd, for the bigger, clean glassy conditions, and Thursday morning, August 13th, for the long-period groundswell in glassy conditions – but that one is smaller and further out, so less certain. If you’re an experienced surfer, the 3rd is your day.

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.
