The Lowdown
Alright, folks, Rusty here. Let's have a look at what's on offer at Infernillo over the next couple of weeks.
Right off the bat, the first few days are a bit of a write-off. Friday and Saturday are looking pretty average with messy cross-shore winds and middling conditions. The real story starts to build late Sunday the 19th. We’ve got a nice little window of glassy conditions with a clean 5-foot swell from the WNW, with a period of 11 seconds giving it some decent shape. The water is sitting at 55°F, which is about normal for the time of year, so no surprises there.
The standout for the whole period, no question, is Tuesday the 28th. This is the one to circle. We’ve got excellent surf conditions for experienced surfers, with a solid 8-foot swell from the West, a very long 13-second period, and glassy conditions all morning. The combined energy reading is a powerful 1728, so there’s plenty of punch in the water. This is a proper groundswell, and on a reef and point setup like Infernillo, it's going to produce some long, well-shaped walls. The crowd factor is "sometimes," so you might get a few out, but with that size, it’ll be worth the paddle. The size is over 8 feet, so this is really for experienced surfers only.
The day before, Monday the 27th, is also a very solid option. It’s a bit smaller at 6 feet, but still glassy in the morning with a 10-second period, offering clean and fun waves.
Looking further out, Wednesday the 29th morning is worth a mention. It’s a bit smaller at 4 feet, but the wind is offshore and gentle, making for a clean, user-friendly session.
The second week is a bit more hit and miss. There’s a couple of days with some size, like the 6-foot swell on the 1st of August, but the wind is a bit messy, so it’s not the cleanest. The consistent theme is that the best windows are in the mornings when the wind is lighter.
So, to sum it up: the first few days are a skip. The best bet is the 27th and the absolute standout is the 28th of July. Get on 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.
