Isla Negra Surf Forecast and Surf Report

Alright folks, Rusty here with a look at what’s coming for Isla Negra over the next couple of weeks. It’s a bit of a slow burner, but there are a couple of sessions worth marking on the calendar.

Right now, we’re looking at a trickle of swell with only weak energy (42). Tuesday the 11th has tiny 1ft waves out of the WSW with a super long 15-second period. The water temp is sitting at 57°, which is a touch warmer than normal for this time of year, so that’s something. But with a 10 km/h S breeze holding it clean, it’s really only a paddle-around wave.

Wednesday the 12th morning sees a jump in energy to moderate (210) as the swell bumps to 1ft, still from the WSW, with a 19-second period. That’s a long-period groundswell, so at this reef break it could offer some decent shape. The cross-off wind keeps it tidy, but it’s still pretty small.

The real standout is shaping up for Thursday morning the 13th. We’ve got 3ft of WSW swell with a 16-second period, and the energy is pushing up to a strong 512. But the beauty is the glassy conditions—WNW wind at just 5 km/h, making it flat calm. Expect very good surf conditions for the advanced crew. This is the pick of the first week.

By Friday the 14th the wind swings onshore from the NNW, and waves get messy. Saturday the 15th is a no-go with onshore winds and 5ft swell that’s getting chopped up.

Sunday the 16th morning brings another window: glassy conditions with 3ft of WSW swell and a 13-second period. The energy is moderate (336), and it should be clean again. Good for a Sunday session.

Looking into the second week, things get more interesting for the big-wave hunters. Wednesday the 19th morning has 5ft waves out of the WSW with strong energy (947). Clean cross-off winds make for another standout: expect very good surf conditions. This one’s getting into big territory for beginners, though.

Thursday the 20th morning holds 6ft of serious swell from the WSW, with a 12-second period and true offshore SSE wind at 15 km/h. The energy is a massive 813. This is expert territory only—too big for most. The wave comment says expect very good surf conditions, so the crew that can handle it are in for a treat.

Friday the 21st morning is also solid: 5ft, offshore wind from the S at 20 km/h, and moderate swell energy (540). Clean, strong, and for the experienced.

After that, it fades fast. From the 22nd onward we get a gap of a few days with nothing worth chasing—tiny 2ft or less, and by the 24th and 25th it’s all onshore junk. There’s a little pickup on the 25th Tuesday morning with 3ft, glassy, and good conditions, so keep an eye on that one for a sneaky session.

So bottom line: if you’re an expert, circle Thursday 20th and Friday 21st. For the rest of us, Thursday the 13th morning and Sunday the 16th morning are the cleanest small-wave windows.

Rusty.
