The Lowdown
Alright, Rusty here. Let's take a look at what's shaping up for Algarrobo.
We've got a bit of a rough start ahead, with the first decent surf not rolling in until Wednesday afternoon, July 15th. After that, there's a nasty stretch of strong, onshore winds that will pretty much ruin the surf from Thursday through Saturday morning. The wind's going to be howling, up to 37 mph, so honestly, you might as well stay home or go for a hike. The swell will be messy and blown out.
But hold on, because things change in a big way on Sunday morning, July 19th. That's when we get a proper window. The wind drops right off – glassy conditions, a slight air from the East at just 3 mph. The swell is a solid 4.6 ft from the WNW with a 12-second period. That's a nice, clean groundswell with good energy behind it (combined energy of 678). The water is 54°, which is a bit colder than normal for this time of year, so don't forget your hood. Algarrobo is a reef and pier set-up that loves a SW swell, and this WNW is close enough to get those lines wrapping in nicely. This is your standout session for the week. It'll be clean, with some real push.
Sunday afternoon holds up too, with the swell shifting slightly west and a light cross-off breeze keeping the face clean.
Looking further ahead, the highlight of the whole 16-day run looks like Thursday morning, July 23rd. We're talking a solid 7.9 ft swell from the WSW, with a 12-second period. The combined energy is a powerful 1594. This is big, expert-level surf. The wind will be a light cross-off from the SE at just 3 mph, so the conditions will be absolutely pristine. This is a serious swell for experienced surfers only – it will be fast, powerful, and a bit of a handful. Don't even think about it if you're not comfortable in overhead surf.
After that, the following week sees some smaller, cleaner swells, but nothing that tops that Thursday. We have a couple of glassy mornings and clean afternoons, but the swell drops off and the winds start coming from the south again, putting a bit of a chop on the surface. There's a big, very long-period swell on the 30th with a 15-second period and 9.8 ft faces (combined energy 2790), but it's coming with a cross-onshore wind, so it will be rough and choppy. That kind of period is best saved for a point break, not a reef exposed to the wind.
So, for your best bets: Sunday morning, July 19th for the clean, fun, intermediate-friendly waves, and Thursday morning, July 23rd for the big, clean, expert-only session. Keep an eye on the forecast as we get closer, the longer-range stuff can always shift.
Stay stoked.

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.
