The Lowdown

G’day, Rusty here. We’ve got a solid 16-day window ahead for Infernillo, but it’s a slow-burner. The first week is mostly a write-off with messy cross-shores and choppy conditions, but there’s some real magic waiting for us near the end of the first week and into the second. Persistence will pay off if you’re after the clean stuff.

The water is sitting at 57°F, which is a bit warmer than the long-term average for this time of year – about 2°F warmer, so you’ll notice the difference. It’s not a big anomaly, but it’s a nice touch.

Tuesday morning (1st September) kicks off with a small 4ft WSW swell at 10 seconds, but it’s cross-shore and only marginal. The combined energy is moderate (462). Not worth paddling out for. By the afternoon, it’s even worse – poor conditions with a 4ft SW swell and cross-shore wind. Wednesday and Thursday are similar: small, choppy, and frustrating. The best you’ll get is a 6ft WSW swell on Thursday afternoon, but with 19 mph cross-shore winds, it’s lumpy and only for the keen. Combined energy jumps to strong (1429), but the wind is a killer.

Friday (4th September) stays marginal, with a 6ft SW swell in the afternoon, but the period drops to 8 seconds – short-period wind swell, so it’s not going to have much shape. Combined energy is moderate (928). Saturday morning (5th September) sees a 3ft SW swell with a long 18-second period, but it’s cross-shore and still marginal. The energy is strong (1205), but the wind is a letdown.

Now, here’s the standout. Sunday morning (6th September). Glassy conditions with a 6ft SW swell at 15 seconds, and the combined energy is very strong (1308). This is the best of the first week – clean, exposed reef and point break, with that long-period groundswell wrapping in from the SW. The crowd profile is “sometimes,” so you might have company, but for a wave this good, it’s worth it. The afternoon stays glassy, dropping to 5ft, still excellent. This is your window.

Monday (7th September) through Wednesday (9th) is mostly cross-on and marginal again. The swell holds around 5ft, but the wind is onshore or cross-onshore, making it choppy. Not worth a special trip.

Thursday (10th September) afternoon brings a 6ft SW swell, but with 9 mph cross-on wind, it’s still marginal. The energy is strong (1205), but the wind is messy.

Here’s the second true standout. Sunday morning (13th September). Clear skies, cross-off wind from the SSE at just 3 mph, and a 5ft SW swell with a 16-second period. The combined energy is strong (941). The cross-off wind will keep the faces clean, and that long period means proper energy and good shape. The afternoon is cross-shore, so get it in the morning.

Monday morning (14th September) is also worth a mention – glassy, 3ft SW swell at 14 seconds, combined energy moderate (436). Clean, small, but fun.

The last few days (15th and 16th September) are mostly marginal with small swell and onshore winds. Wednesday morning (16th) has a 5ft W swell, but it’s onshore, so expect mess.

Overall, the best bet is Sunday morning (6th September) for the glassy, 6ft SW groundswell. The second-best is Sunday morning (13th September) with the clean cross-off and 5ft SW swell. The rest of the window is a mix of marginal and poor conditions, with some small windows of fun surf. There’s no surf in the first couple of days until Tuesday morning, and then a gap of marginal days until the Sunday standouts.

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.
