The Lowdown
Alright, this is Rusty, and I’m looking at your local surf outlook for Infernillo. Let’s get into it.
We’ve got a solid run of surf on the horizon, but it’s not all gonna be perfect. The water temp here is sitting at 56°F, which is about what you’d expect for this time of year, so no surprises there.
The best bet, the real standout, is shaping up to be Monday, August 10th. The morning session is looking prime. We’ve got a clean 7ft WSW swell rolling in with a good 13-second period, and the wind is light and off the shore. That’s going to be clean, powerful, and pushing some serious energy (1545). This is for experienced surfers only, though – that size is not for the beginners. The afternoon gets a bit bumpy, so get out there early.
Before that, the week starts off a bit average. Wednesday the 5th and Thursday the 6th have some size (8ft), but the winds are messing with the surface. Wednesday morning is cross-onshore, and Thursday has a strong cross-shore that’s going to chop it up. The energy is high (2130 and 1433), but the quality isn’t there for a great ride.
Friday the 7th is a write-off, with poor conditions and dropping swell. Saturday the 8th is a bit of a beast – that 10ft SW swell packs a huge punch (3318), but the morning cross-shore and the afternoon onshore winds are going to make it a messy, choppy beast. That’s more for the kite surfers than paddle surfers, to be honest.
The next real highlight is Tuesday, August 18th. The morning is looking glassy, with a clean 4ft swell from the WSW and a long 16-second period. The energy is moderate (1120), but that glassy surface and the long period will make for some really nice, well-shaped waves. This is a great call for an intermediate surfer.
The second week starts to taper off. Mid-August sees a lot of small, weak swell (under 3ft) and poor wind. The 13th of August has a couple of glassy mornings, but the swell is tiny (3ft to 3ft). It’s pretty, but not a lot of push. The 20th of August has some 6ft swell, but it’s getting blown out by a strong cross-shore wind.
Overall, there’s a good run of swell, but the wind is the real story here. You have to pick your windows. The 10th and 18th are the ones to circle. The rest of the time, it’s a mix of cross-shore chop and onshore slop, so you’ll be working for it.
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.

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.
