The Lowdown
Right folks, Rusty here. Let's have a look at what's cookin' for Algarrobo over the next couple of weeks.
We start off with some pretty grim conditions. Tuesday the 21st is a write-off with heavy rain and a raw 25 mph nor' wind making a mess of things. Forget it. The water's sitting at 55°, which is about normal for this time of year, nothing to write home about.
The real action kicks off on Wednesday the 22nd of July. The morning is looking absolutely pristine – glassy conditions, not a breath of wind, and a solid 6 ft swell rolling in from the WNW. The combined energy is a solid moderate (768), and the period is a nice 10 seconds. That's good, clean, fun surf. The afternoon holds up with glassy conditions too, just a touch smaller at 5 ft. This is the standout window of the first week.
Thursday the 23rd and Friday the 24th get a bit tricky with some cross-shore wind and marginal conditions, though there's still some size in the water. The swell on Friday morning hits 7 ft (1028 energy), but the wind is a bit messy.
Saturday the 25th of July dawns with another glassy morning, a beautiful 4 ft swell from the west with a 10-second period. It's clean, it's fun, and the energy is moderate (633). A solid morning session.
Now, Sunday the 26th is where it gets interesting for the more experienced crew. The morning brings a 5 ft swell from the west, with a 13-second period. That's a proper groundswell, pushing the combined energy into a strong 1185. The wind is a light offshore cross-off, so it's going to be clean and powerful. This is a standout for the slightly bigger wave hunter.
The early part of the following week, Monday the 27th and Tuesday the 28th, we see the swell really start to pump. Monday morning has a solid 7 ft W swell (1564 energy) with a clean cross-off wind. The afternoon is even better with glassy conditions and 6 ft. Both are excellent for experienced surfers. Tuesday has a bit more size at 7 ft from the WSW, with a 12-second period. The energy is very strong (1695), but the wind is a bit stronger. Still, clean conditions.
Wednesday the 29th of July is another true standout. The morning is glassy, with a 7 ft swell from the WSW at a 13-second period. The combined energy is a massive 1630. This is big, powerful, clean groundswell – the kind that makes a reef break like Algarrobo really hum. Experienced surfers only, this is the pick of the whole forecast.
The end of the run gets a bit wild. Thursday the 30th sees strong winds return, and then Friday the 31st of July to Saturday the 1st of August bring a massive, powerful swell. We're talking 10 ft (2934 energy) on Friday, with a 14-second period. That's a lot of water moving around, and it's pushing into the weekend. The wind remains cross-off, so it'll be clean, but this is proper big-wave territory. The following Monday and Tuesday look to drop back in size and settle down with cleaner conditions again.
So, to wrap it up: the best of the best is the glassy mornings on Wednesday the 22nd and Saturday the 25th for a fun, clean session. For the more experienced surfer, you absolutely cannot miss Sunday the 26th and especially Wednesday the 29th of July for that powerful, clean, long-period groundswell. Algarrobo is set to fire.
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.
