The Lowdown
Alright, let’s break down what’s cookin’ at Infernillo.
We’re starting today, Thursday the 30th of July, but don’t rush out just yet. The swell is about 4ft from the west, with a cross-off breeze, but the energy is weak (340). The call is marginal with iffy tide conditions. It’s surfable, but nothin’ to write home about. The water is sittin’ around 56°, which is about normal for this time of year.
Friday the 31st is a washout. Swell drops, wind turns cross, and by the afternoon, light rain and a cross-chop kill it. Skip it.
Now Saturday the 1st of August – things get interesting. We’ve got a 7ft swell from the southwest, with a solid 13-second period (groundswell) and combined energy at 1502 – that’s strong. The wind is a clean cross-off, so the waves will be well-groomed. This is a point and reef setup, so that long-period groundswell will wrap in real nice. It’s a bit much for beginners at 7ft, but you intermediate guys are in for a good one. Crowds are possible, so get there early.
But the absolute standout, the one you’ve been waiting for, is Sunday the 2nd of August. The morning sees 8ft from the west, with a 6 mph offshore breeze, and the energy is huge (1838). The afternoon is where it gets magic: the same 8ft swell, but with a glassy surface and the wind swinging to the west-southwest at just 3 mph. This is what we live for. The wave quality is rated excellent for experienced surfers, but if you’ve got the skills, this is the best day of the whole forecast. Powerful, clean, and lined up. A top-tier session.
Monday the 3rd keeps the quality cranked. 7ft in the morning, glassy, from the west-southwest. The energy is still strong (1398). Another excellent day for the experienced crew, with clean conditions and a solid swell.
The middle of the week, from Tuesday the 4th to Thursday the 6th, the swell hangs around 6ft to 7ft, but the wind turns cross-shore or cross-on, bringing in a bit of chop. The quality dips to marginal, but it’s still surfable, especially if you don’t mind a little texture.
Then we get a sweet little window on Friday the 7th and Saturday the 8th of August. The swell drops to about 4ft from the southwest, but the wind goes glassy or light offshore. The energy is moderate (around 687-699), but the surface will be clean and smooth. These are great days for a longboard or a funboard. The wave quality is called “very good,” so you’ll be stoked.
Sunday the 9th of August brings a nice 5ft southwest swell, with a 13-second period and a clean morning. The energy is strong (1147). This is another excellent option for experienced surfers, with clean conditions.
The second week gets a bit more mixed. From Monday the 10th onwards, the swell stays between 4ft and 5ft, mostly from the southwest, but the winds get more variable. There’s a notable day on Thursday the 13th of August with a 4ft swell from the southwest, but a very long 16-second period – that’s proper groundswell energy. The wind is cross-off in the morning, so it will be clean, but the energy is still moderate (1101). Worth a look.
Overall, the clear winner is Sunday the 2nd of August. Mark it. The second best is the glassy morning of Monday the 3rd. After that, the weekend of the 8th-9th is a solid, fun option. The second week has a few slower days, but nothin’ to worry about.

Information about the Infernillo Surf forecast
The above surf forecast table for Infernillo provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Infernillo can be found by selecting the local surf guide option on the grey menu. Our Infernillo 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 (Infernillo) 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 Infernillo 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.
Infernillo is 67 km (42 miles) from Santa Cruz. If you plan a holiday in Santiago, look for hotels and other accommodation in Santa Cruz. Santa Cruz has rooms for a wide range of budgets as well as car hire and transport links.
