The Lowdown
Alright, let's get into it. The next couple of weeks here are a mixed bag, to be honest. We've got a real window of hope in the middle, but it's surrounded by a lot of nothing and some proper slop. The start of the period is pretty poor, with barely a ripple worth paddling for. It’s not until Monday the 17th that things start to look like they might turn on.
The standout of the whole stretch is shaping up to be Tuesday the 19th of August. We’ve got a solid swell coming from the WSW with a proper long period of 15 seconds – that’s some real groundswell energy. The combined swell energy will be strong, hitting 1786 in the morning and 1504 in the afternoon. It’s around 7ft, which is a decent size for Infernillo. The morning has a light cross-shore breeze, but the afternoon glass is nearly off with only a slight onshore touch. This is the day to be out there. Keep in mind, it will be too big for the groms and beginners at over 5ft.
The week leading up to that is a slow climb. Friday the 15th and Saturday the 16th have some waves, but the winds are messy and the periods are short, so it’ll be lumpy. Sunday the 17th is interesting – clean conditions with a light offshore start and a glassy afternoon, but it's only around 4-4ft. It'll be clean, but not a lot of push. Infernillo is a reef and point break, and it loves a good long-period SW swell, so that 13-second pulse on the 17th will be better shaped than the shorter-period stuff we see before it. That one on the 19th is the real deal though.
After that, the surf sort of fades out. We get a pulse of windswell around the 22nd and 23rd, but it's not going to be anything special. Then there’s a proper dry spell before a big, raw spike on the afternoon of Tuesday the 25th. That one comes in at a hefty 12ft from the WNW, with strong energy of 3497, but the quality looks poor with a short 11-second period and a cross-off wind. Over 8ft is expert-only territory, and at a point like this with that much energy, it's going to be a washing machine. Not one for the faint-hearted. The last few days of the month drop off into small, poor conditions, with one notable last-gasp glassy day on the 28th, but the swell will be tiny.
So, mark your calendar for the 19th. That's your best shot at something truly memorable. The rest is about picking the clean moments in smaller surf. Keep the faith.

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.
