The Lowdown
Alright, Rusty here with a look at what’s coming our way for Infernillo. It’s a bit of a mixed bag over the next couple of weeks, but there are definitely some windows worth paddling out for.
We’ve got a bit of a slow start, so don’t rush to wax up just yet. The first real action kicks off Thursday morning, the 10th. Infernillo will be seeing a clean 4ft SW groundswell with a nice 13-second period, and light cross-off winds making for tidy waves. The water’s sitting at about 56°, which is pretty normal for this time of year. The combined swell energy is moderate (411), and it’s got that reef and point setup working well. This is a solid intermediate option to ease into the forecast.
Friday morning, the 11th, is a little more marginal with a 4ft WSW swell and light cross-shore breezes, but it’s not going to be as clean as Thursday.
The standout window looks to be Sunday morning, the 13th. We’ve got a punchy 3ft WSW groundswell with a very long 18-second period, and offshore winds from the ESE at just 6 mph. That’s a recipe for smooth, lined-up waves. The energy here is strong (817), and with offshore conditions, Infernillo’s reef and point should be firing for the experienced crew.
Then Monday morning, the 14th, is another one to circle. A 4ft SW groundswell with a 15-second period and light cross-off winds, the combined energy is very strong (1018), and the report calls it excellent for experienced surfers. That’s the one for the advanced paddlers.
From there, the forecast gets a bit patchy with afternoon onshores ruining the fun most days. There’s a brief moment on the 25th morning with a clean 3ft WSW swell and offshore cross-off winds, but the energy is weaker (266). Overall, the first week has the best bets, with the second week looking less reliable.
So, if you’re after the best of it, get out there Sunday the 13th or Monday the 14th. The rest of the time, keep an eye on those morning windows.
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.
