The Lowdown
Alright, surfers, Rusty here. Let’s get straight into it for Infernillo. This forecast is a bit of a rollercoaster, so let’s break it down.
The next week and a half is going to be a game of patience. We’ve got a solid pulse of swell coming in right now, but the winds are going to be all over the place. The real standout is going to be Saturday morning, the 8th. We’re looking at a solid 12ft SW groundswell with a period of 14 seconds, and the wind is dead glassy. The energy is strong, clocking in at 4471, which is serious power. This is going to be a beast of a day at the reef and point, with clean, powerful lines. It’s a bit much for the beginners, but for the experienced crew, this is the one to circle. The water temp is 57°F, which is about normal for this time of year, so don't expect any surprises there.
Saturday afternoon the wind swings around to a light cross-on, and the swell backs off a touch to 10ft. It’s still big, but the surface won't be as perfect.
Sunday the 9th sees more swell, but the wind is getting messy. The morning is a cross-shore breeze with 8ft waves, and by the afternoon it's a choppy cross-onshore mess. The energy is still strong, but it’s not going to be clean.
Monday the 10th drops to around 7ft, and the wind stays cross and light. It’s rideable, but nothing to write home about.
By Tuesday the 11th, the swell really drops off. We’re looking at ankle-to-waist high waves, around 4-4ft. The conditions are glassy, but there’s just not enough push. This is where the first real gap starts. From Tuesday through to Thursday the 14th, it’s pretty small. There are some clean moments, especially Thursday afternoon when it goes glassy again with a 4ft W swell, but it’s small.
Now, here’s where it gets interesting. The swell builds again on Saturday the 15th, jumping to 8ft. The wind is light cross-shore, so it's not perfect, but there’s some power back in the water. Then Sunday the 16th brings a proper cross-off wind, with 8ft waves. The morning is clean, but the afternoon turns into a lumpy, rainy mess with a fresh cross-shore breeze. That morning window on Sunday could be a good one.
After that, the energy fades out again. The middle of the week looks small and a bit choppy. But then, another pulse shows up on Wednesday the 19th. That morning looks like another standout. We’ve got a 7ft WSW swell with a light cross-off wind and clean conditions. The energy is solid at 1553. This is the other one to keep an eye on.
The last few days of the window fade out. The 22nd has some glassy 4ft waves, but it’s small. The 23rd gets blown out by a strong N wind and some rain. All in all, we have two clear highlights: Saturday the 8th and Wednesday the 19th. Both have the size and the clean conditions. Everything else is a waiting game.
This reef and point set up is best when the swell is coming from the SW, which it is for the main events. It’s a consistent break, so it’s always worth a look, but the winds are going to be the deciding factor.
That’s the picture from here. Stay stoked.
Rusty.

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.
