The Lowdown

G’day, Rusty here, and I’m looking at the Infernillo stretch for the next couple of weeks. Bit of a slow start, but there’s a proper pulse of energy building that’s going to deliver some serious, clean swell for those who can handle it.

Right now, the water temp is sitting at 57°, which is about 2° above the long-term average for this time of year—pretty much what you’d expect, no surprises there.

The first few days are flat. Sunday the 23rd and Monday the 24th are write-offs, with weak, messy waves and onshore or cross-shore winds. The combined energy is around 178 to 180, which is weak. Nothing worth paddling out for.

Things start to look interesting on Tuesday the 25th morning. We’ve got offshore wind from the east at 6 mph, and a 3ft WSW groundswell with a long period of 15 seconds. The energy jumps to 338, and the conditions are clean. This is a promising start, but it’s the calm before the storm.

Wednesday the 26th is the standout. Morning sees 6ft from the west with a period of 10 seconds, offshore ENE wind at 6 mph, and the energy ramps up to 898. The call is “very good surf conditions.” By the afternoon, it gets even better: 6ft WSW, period 12 seconds, cross-offshore NE wind, and a combined energy of 1033. The report says “excellent surf conditions for experienced surfers.” At 6ft, this is solidly intermediate to advanced territory, but the clean conditions will have Infernillo’s reef and point setups running well. Crowds are sometimes an issue here, so be ready to share.

From Thursday the 27th morning, the swell size jumps to 13ft from the WSW with a period of 15 seconds. The energy is a massive 6721. The wind is cross-shore from the north at 6 mph, so it’s a bit mixed. This is big, powerful, and only for experts—over 8ft is no place for beginners. The period is very long, which can make the point break work beautifully, but the beach sections might close out. The afternoon stays at 12ft with a 14-second period and still cross-shore wind.

Friday the 28th offers the cleanest conditions of the big swell window. Morning has 10ft WSW, 13-second period, with a light cross-offshore NNE breeze. The energy is 3194. By the afternoon, it goes glassy with a 3 mph WNW wind—absolutely pristine. This is another standout session for experienced surfers. The energy drops slightly, but the glassy face will be a dream.

Saturday the 29th sees the swell start to back down to 7ft in the morning, with a light cross-onshore wind from the southwest. The energy is 1195. It’s still rideable, but the offshore wind is gone, and the conditions are marginal. Sunday the 30th drops further to 5ft with a 11-second period and a cross-shore north wind, but the energy is 552, and the quality is poor.

The second week gets more inconsistent. Monday the 31st to Thursday the 3rd of September has some pulses of 5ft to 8ft swell from the WSW, but the wind is often cross or cross-onshore, and the conditions are marginal. The combined energy for that period ranges from 571 to 4598—moderate to strong, but the wind keeps it messy. The standout morning of that stretch is Thursday the 3rd, with 7ft, a 13-second period, and cross-shore south wind, but it’s still not as clean as the first week.

Friday the 4th of September sees 8ft WSW swell with a 14-second period, a light cross-shore south wind, and 2636 energy. The conditions are marginal. Saturday the 5th afternoon looks better: 7ft WSW, 12-second period, cross-offshore NNE wind, and 1105 energy. The report says “excellent surf conditions for experienced surfers,” making that the best call for the second week, but at over a week out, treat it as promising rather than guaranteed.

The final day, Monday the 7th of September afternoon, has 4ft from the west with a 11-second period, glassy conditions with a 3 mph WNW breeze, and 518 energy. It’s a nice, clean end to the run.

If you’re an experienced surfer, don’t miss Wednesday the 26th or Friday the 28th. That’s where the magic is.

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.
