The Lowdown

Alright folks, Rusty here. Let's take a look at what's coming down the line for Infernillo. This is a reef and point set-up that's consistent and exposed to the swell. The water is sitting at 56° today, which is pretty much spot on average for this time of year, so no surprises there.

The real standout is going to be Thursday morning, the 27th of August. We've got a solid 12ft swell pumping in from the WSW with a long 14-second period. The energy is right up there at 5668, which is strong. Winds are glassy from the West, making for some absolutely clean, powerful waves. This is proper expert territory though—that size is for the experienced crew only. It's the best of the whole run.

Before that, Wednesday the 26th isn't too shabby either. You've got a 6ft to 8ft swell from the west and WSW, with glassy conditions both morning and afternoon. The energy is in the moderate range (1078 and 1458). It's excellent for experienced surfers, but the Thursday swell is just on another level.

After that Thursday morning peak, the wind starts to get a bit messy. Thursday afternoon turns cross-on, and Friday through the weekend is a bit of a mixed bag with cross-shore and cross-on winds, making things a little bumpy. The swell stays decent, around 7ft to 10ft, but the conditions aren't as clean. Saturday morning the 29th looks like a nice window of opportunity though—glassy winds, 7ft WSW swell, and moderate energy at 1102. That's a good one to pencil in.

We hit a bit of a lull from Sunday the 30th through to the start of September. The swell drops, winds get onshore, and the quality takes a dive. It's a bit of a flat spot for a few days, not much to get excited about.

Things start to look a little more interesting again around the 8th of September. Tuesday the 8th has glassy morning winds, a 5ft SW swell with a long 15-second period, and clean conditions. The energy is moderate at 1183. That's a promising one for the second week, but we're getting a bit further out, so keep an eye on the forecasts.

For the rest of the second week, it's a bit of a mixed picture with winds swinging around. The 9th of September has some potential with glassy conditions and a small 4ft to 4ft swell, but it's not the size we saw earlier. The 10th brings some strong winds, so probably not the best time to paddle out.

Overall, the pick of the window is Thursday morning the 27th. Epic, but bring your big-wave board and your courage. Saturday the 29th morning is a solid backup. The rest of the time, you'll be picking through the rougher conditions.

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.
