Table - best surf conditions forecast for Infernillo over the next 16 days.
G’day, Rusty here. Let’s talk about what’s on the menu at Infernillo for the next couple of weeks. It’s a reef and point break that loves SW swell, and when it’s on, it’s a beauty. But the start is a bit flat and average.
Sunday the 12th kicks off with small 3-foot (1.0m) SW swell, light cross wind, and the energy is moderate at 428. Tides and conditions are marginal, so not one to get stoked about. Monday the 13th is a big change – swell jumps to 8 to 10 feet (2.3m to 3.0m) with a long 18-second period from the WSW, and the energy cranks up hard to 3421. That’s big, powerful groundswell, and with the water temp about average for the season, it’s a day for the experienced crew only. The morning is cleaner with light cross winds. Tuesday the 14th stays big at 10 feet (3.0m) with strong energy (3215), but the wind turns a little onshore, so the quality slips a notch. Still expert territory.
Wednesday the 15th drops to 4 feet (1.1m) from the SW in the morning with a clean cross-off breeze, and the energy is moderate at 598. A decent size for intermediates, but the surf conditions are still marginal. Thursday and Friday (16th and 17th) are a write-off – strong to gale-force winds and tiny, poor surf (2 feet / 0.6m to 0.8m).
After a few days of flatness, Saturday the 18th brings back 10 feet (3.0m) from the NW, but the wind is cross and there’s rain, making it messy. Energy is strong at 2711, but it’s a tough one. Sunday the 19th is the real standout: 8 feet (2.3m) from the WNW with a clean cross-off wind, solid energy at 1929, and the direction is right for the point. Crowds are only sometimes, so you might have a few mates out, but the quality makes up for it. This is the session to circle.
Monday the 20th is huge again (12 feet / 3.5m) but blown out by strong winds and poor conditions. The rest of that week fades out with smaller, cross-breeze slop. By Thursday the 23rd, it’s glassy and tiny (1 feet / 0.4m) with a very long 21-second period – that’s a real long-groundswell, and at a point break like Infernillo, it can make for some clean little lines on a longboard. Energy is weak (299), so it’s a chill day.
Out toward the 26th and 27th, the morning of the 26th has a 3-foot (1.0m) WSW swell with a clean cross-off breeze and moderate energy (412). Light waves, a nice little window before the wind picks up.
Best bets? Monday the 13th for the big-wave hunters, and Sunday the 19th for the all-round clean, solid session. Get amongst it if you can.
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.
