The Lowdown

Right, mate, Rusty here. Let’s look at what’s on offer for Infernillo over the next sixteen days.

The outlook starts on Saturday, 29 August with a clean-looking picture, but there’s a catch. We’ve got a solid 7 ft groundswell from the west-southwest (period 12 seconds – plenty of punch) early on, and the water is sitting right around 57°F, which is nothing unusual for this time of year. The energy is strong too (1180 combined energy). However, the wind has been coming from the northwest at only 3 mph, which puts it in a cross-on position, so the surface isn’t glassy. It’s still clean enough to paddle out, but it’s not perfect. Because the swell is over 5 ft, it’s not a beginner wave, but it’s manageable for an intermediate crew. Infernillo is a reef and point setup, and for a point break, that WSW direction (matching the optimum direction of SW well enough) will hold up nicely. The crowd factor says “sometimes,” so you won’t be alone on a wave like this.

That Saturday morning is the best I can honestly call out in this window. After that, things drop off. The swell fades through Sunday and Monday, settling into a 5 ft range with cross-on breezes keeping the surface a little bumpy. By Tuesday, 1 September, it’s down around 4 ft with wind picking up and the scores drop right off – weak energy, poor conditions. There’s a long gap of weak, messy surf, and honestly, from that Tuesday right through until Sunday, 6 September, there’s no standout. The best you’ll get is a 4 ft early on Sunday, 6 September with a very long period of 16 seconds and offshore wind from the west at only 6 mph. That’s a clean shot, even if the swell is a bit small. The energy is moderate (1134 combined) but that long period groundswell will wrap nicely around the point, leaving longer gaps between sets – good for a breather. That Sunday morning is the other small highlight.

For the second week, it gets pretty marginal. There are some 5 ft to 6 ft pulses, but the period drops short (8-10 seconds) and the winds are mostly cross-on or cross, making it choppy and sloppy. Nothing worth setting the alarm for. The last week of the window has some 5 ft swell, but again, the wind and short period ruin it. Infernillo can handle a messy day, but not when the wind is in your face.

So the only two windows worth circling are Saturday morning, 29 August for the biggest, cleanest swell of the outlook, and Sunday morning, 6 September for a clean, long-period groundswell if you want to wait.

Stay safe, hit the point, and keep your eyes peeled.

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.
