The Lowdown

Alright folks, Rusty here. Let’s talk about what’s cookin’ at Infernillo over the next couple of weeks.

We’ve got a bit of a slow start to the week, but nothing to get too down about. The first couple of days are a write-off with heavy rain and strong cross-shore winds making a mess of things. The wait is worth it, though.

The real action kicks off on the morning of Wednesday the 22nd. Infernillo is a reef and point set-up, and it’s gonna be pumping. We’re looking at a solid 7ft swell from the WNW, and with a light cross-offshore breeze, it’s going to be clean. The combined energy is huge, hitting 1111 (moderate to strong), so there’s plenty of push. This is excellent surf for experienced surfers, so if you’ve got the skills, be there. The water temp is sitting at 55°, which is spot on for this time of year, no surprises there.

Thursday the 23rd drops off a bit in the morning with a smaller 5ft swell, but the afternoon picks up again to 8ft from the W with a period of 11 seconds. The wind stays cross-off, so it’s still clean, but the tide or something is making it a bit marginal. Not a total loss, but not the best of the run.

Now, Friday the 24th is a real standout. Morning session is the one to chase. You’ve got a 8ft swell from the W, combined energy at 1353 (strong), and a light cross-offshore breeze. That’s a recipe for excellent conditions for the experienced crew. The afternoon gets a bit cross-shore, so get out early.

Saturday the 25th sees a drop in size, down to 3ft, but look at that period – 15 seconds! That’s some proper long-period groundswell. The wind is offshore in the morning, so it’ll be glassy and clean. This is a point and reef, so that long period will wrap in beautifully. It’s a smaller day, but quality over quantity.

Sunday the 26th is a mixed bag. The morning has a tiny 2ft swell with a very long 18-second period, but it’s clean. The afternoon turns ugly with a fresh cross-shore and lumpy 6ft wind swell. Not worth paddling out in the arvo.

Monday the 27th brings a big jump in size, with a 10ft swell from the W. That’s big, expert-only territory. The wind is cross-shore, so it’s going to be a bit of a battle. The combined energy is a massive 2677 (very strong). This is for the brave, not the faint of heart.

The real magic happens on Tuesday the 28th. The morning is glassy – dead flat wind – with a 7ft swell from the W at 12 seconds. The combined energy is 1302 (strong). This is excellent for experienced surfers. It’s clean, it’s powerful, and it’s all yours if you can handle it.

We’ve got a bit of a lull after that, with smaller swells and less favourable winds through the end of July. But hang on, because the first week of August is looking like a beast.

Friday the 31st of July is a hidden gem. The morning has a 7ft WNW swell with clean conditions, and the afternoon bumps up to 6ft with combined energy at 1339 (strong) and excellent conditions. That’s a solid day.

Saturday the 1st of August is glassy all day. Morning has a 5ft WSW swell, and the afternoon is dead calm with a 5ft WNW swell. This is a perfect day for a long, clean session.

Now, the real heavy stuff arrives. Sunday the 2nd of August, we’re looking at an 12ft swell from the W with combined energy of 3334 (very strong). This is huge, and it’s only for the most experienced. Monday the 3rd is similar, and Tuesday the 4th is the one to circle. The morning is glassy with an 12ft WNW swell, but the afternoon is the standout: 12ft from the W with a 14-second period, a gentle offshore wind, and a combined energy of 4391 (very strong). That is as good as it gets for experts. This is a date to remember.

The 5th of August still has a solid 7ft swell with glassy conditions in the morning, but the wind turns onshore in the afternoon.

So, to wrap it up: the best on offer are the morning of the 22nd of July for a solid start, and the afternoon of the 4th of August for the absolute biggest, cleanest, and most powerful swell of the run. The 1st of August is your pick for a clean, fun, glassy day. It’s a good outlook for Infernillo.

Stay stoked.
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.
