The Lowdown
Alright, folks, Rusty here. Let’s talk about what’s ahead for Infernillo. This reef and point is exposed to the swell, and it’s a consistent spot, so we’ve got plenty to look at. The water temp is sitting about average for the season, nothing unusual.
The week starts rough. Wednesday morning the 15th has a 4ft WSW swell, but that northerly is blowing at 19 mph, making it a messy cross-off. The combined energy is moderate (703), but the wind and a marginal tide call make it a no-go. Wednesday afternoon drops to 3ft from the west with a lighter breeze, but still not worth it.
Thursday the 16th is a write-off. A near gale at 31-37 mph, with tiny, messy swell. Forget it. Friday the 17th isn’t much better—heavy rain, cross-on wind, and a choppy 5ft WNW swell. The afternoon cleans up with a cross-off breeze and 4ft from the SW, but the energy is moderate (634) and conditions are still marginal.
Now, we see a light. Saturday the 18th afternoon has a 5ft WNW swell, light northerly breeze, clean conditions, and moderate energy (545). The score is decent. Sunday the 19th is even better. Morning brings a 4ft W swell with a light SSE cross-off, energy at 517. But the real standout is Sunday afternoon: glassy conditions, 4ft WNW swell, and a calm wind. That’s clean surf, energy at 465. This is your best bet for the near term—small but perfect.
Monday the 20th keeps the good vibes with glassy mornings and 4ft from the SW, then a clean cross-off in the afternoon.
After that, it gets messy again. Tuesday the 21st has a near gale, and Wednesday the 22nd brings a 7ft WNW swell but with a cross-on wind and choppy conditions. Too big for beginners, messy for everyone.
But hold on, because Thursday the 23rd is a big day. A 10ft WSW swell rolls in with a 12-second period. That’s powerful—the combined energy is a massive 2381 in the morning and 2034 in the afternoon. The wind is moderate cross-shore, so it’s not perfect, but for experienced surfers, this is a serious proposition. The swell direction lines up with the optimum SW. This is a standout for the advanced crew.
Friday the 24th morning is a treat for the experienced: 6ft from the SW, clean cross-off wind, and strong energy (1013). Afternoon gets lumpy, but the morning session is excellent.
The last week of the month winds down. Saturday the 25th and Sunday the 26th have tiny, long-period SW swells (17-20 seconds) but the waves are small, and the energy is moderate. It’s a bit slow.
Then we get a promising look at the very end. Wednesday the 30th morning: glassy conditions, 5ft from the west, 11-second period, and moderate energy (556). The forecast calls for very good surf. This is another standout—clean, well-shaped waves for intermediates.
Top picks: Sunday the 19th afternoon for the glassy, clean small waves, and Thursday the 23rd for the big, powerful, expert-only swell. Keep an eye on Wednesday the 30th for a clean, solid session.
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.
