The Lowdown
Alright, let’s get into it. This is Rusty, and I’m looking at what’s on the table for Infernillo over the next couple of weeks. There’s no surf to talk about right now, but don’t worry—it’s coming.
The first session worth paddling out for is Monday morning, September 14. Infernillo is a reef and point break that handles a SW swell really well, and we’ve got a clean 4ft swell from the SW with a 14-second period. That’s proper groundswell, long and lined up, perfect for the point. The wind is light and cross-offshore from the SSE, so expect clean faces. The water temp is 56°, which is a touch warmer than usual for this time of year, about 1° above average, so it’s comfortable.
Tuesday morning the 15th keeps the run going: 4ft from the WSW, period dropping a little to 13 seconds, but still quality. Winds are light and cross-off from the SE, so clean again. Not quite the standout of Monday, but still a very good session.
Wednesday morning the 16th is a real treat—glassy conditions with a light offshore from the SE, and 2ft of WSW swell at 12 seconds. It’s small but clean as a whistle. Combined swell energy is only 205 (weak), so expect gentle, fun waves for a log or a mid-length.
Thursday the 17th and Friday the 18th mornings are both glassy again, with light winds from the SE and S, and clean 3ft to 3ft WSW swells. This is a nice little run of clean mornings, but the swell is modest. Energy sits around 300-340, so still in the weak range.
Saturday the 19th morning is clean with a NE cross-off, 4ft WSW swell at 10 seconds. It’s a bit shorter period, so the waves might be a little weaker, but still fun. Sunday the 20th morning is similar: 4ft, clean, cross-off from the NNE.
Monday the 21st morning: 4ft from the W, period down to 8 seconds. That’s short-period wind swell, but the wind is light cross-off from the SSE, so it’s clean. Tuesday the 22nd morning has 3ft from the SW at 8 seconds, again clean with light SE winds.
Now, the big news is on the horizon. Friday morning, September 25. This is the standout of the whole forecast. A solid 7ft W swell at 13 seconds, long-period groundswell, with light cross-offshore NE winds. That’s clean, powerful, and sets up beautifully for the point. Combined energy is 1426 (strong). This is for experienced surfers only—over 8ft later in the day, so it’s big.
Saturday the 26th morning is even bigger: 7ft from the W at 13 seconds, glassy with no wind at all. Combined energy 1569 (strong). Again, this is expert territory. The point will be handling it well, but it’s a beast.
Sunday the 27th morning is still solid at 6ft from the WSW, 10 seconds, clean with light SSE winds. Energy is 671 (moderate). Monday the 28th morning: 6ft from the W at 10 seconds, glassy with light S winds. Energy 842 (moderate). Both are good, but the 25th and 26th are the real standouts.
There’s a long gap of no surf recommendations until the morning of the 14th, so the first week is mostly quiet. But from the 14th onward, there’s a solid run of clean mornings. Crowds are possible at Infernillo, so keep that in mind, especially on the bigger days. The 25th and 26th are the ones to circle on your calendar.
Rusty out.

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.
