The Lowdown

Alright folks, Rusty here with the outlook for Infernillo. We got a bit of a slow start but there's a few windows to get excited about.

Alright, the good news is we've got a run of swell coming in from the southwest and west-southwest, with that optimum direction of SW lining up nicely with what Infernillo likes. The first standout session is going to be on Thursday morning, August 13th. We're looking at a solid 4ft groundswell from the WSW with a long 15 second period, and with the wind glassy out of the NNW, it's going to be absolutely pristine. Wave energy is strong with a reading of 748 in the tank. This is your best bet for a clean, quality session early in the forecast.

Now, as we move into the weekend, things get a bit wild. Friday afternoon, August 14th is a sleeper hit. The swell picks up to 5ft from the WNW with a shorter 9 second period, but the wind is clean and cross-offshore from the NE. It'll be a bit more crumbly and fun, not as powerful as Thursday, but still a very good option with moderate wave energy (576).

Saturday, August 15th, brings a bigger pulse with 6ft swell from the WNW, but the energy jumps to 1060, indicating strong wave energy. That's getting into the big stuff for Infernillo. It's doable for experts, but beginners will want to sit this one out. The wind stays cross-offshore from the north at 20 km/h, so it'll be clean but a bit of a battle. This setup looks more interesting for kite surfing than paddle surfing honestly.

For the middle of the following week, Tuesday morning, August 18th is another gem. Glassy conditions with a light southerly breeze and a clean 3ft swell from the WSW with a long 15 second period. The energy is still strong at 844, so there's plenty of push for a fun, clean bank.

Looking further out, Wednesday morning, August 19th is where it gets serious. We have a 7ft swell from the WSW with a 14 second period. The combined energy reading is a massive 1560, which is very strong. The winds are light cross-shore, so the lineup will be chunky and powerful. This is experts-only territory, and with such a long period groundswell hitting a reef and point break setup like Infernillo, it's going to be unruly but potentially epic for the experienced crew. The crowd factor is listed as "sometimes" so be ready to share.

After that, we see a slow drop-off into the end of the month with a bit of a gap around the 22nd and 23rd where things get small and marginal again. Sunday morning, August 23rd is worth a mention though: dead calm, glassy conditions with a clean 3ft swell from the SW. It'll be a small but playful morning.

The water temperature is sitting at 56°, which is about average for this time of year. No major anomalies to report there.

Alright, that's the run down. Keep an eye on that Thursday morning and Tuesday the 18th for the cleanest windows. Wednesday the 19th if you've got the skills and the guts.

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.
