Isla Negra Surf Forecast and Surf Report

Alright crew, Rusty here with the lowdown on Isla Negra.

First thing: water temp is about 57°F, which is pretty normal for this time of year. No weirdness there.

The first week is a bit of a mixed bag. Wednesday the 5th kicks off with a 6ft swell from the WSW, but the wind is a light cross-shore from the WSW. The energy is moderate (969). It’s rideable, but nothing to write home about. The afternoon gets a bit better with a light onshore from the NNW and a longer 14-second period, with stronger energy (1440), but it’s still just marginal.

Thursday the 6th has a bit more size. Morning brings a 7ft WSW swell, but the wind is a cross-offshore from the S at 12 mph, keeping things clean. The energy is strong (1112). The afternoon drops to 5ft but the wind picks up to 16 mph. It’s a bit messy, but there are waves.

Honestly, the first week is a dud for anything special. The swell goes flat after Friday the 7th, with a 4ft morning that fades to nothing. From Saturday the 8th through to Tuesday the 11th, we’re looking at tiny waves – 0.7ft to 2ft. There’s a long gap of a few days with almost no surf.

Now, the second week starts to show some life. Wednesday the 12th morning has a 2ft WSW swell, but with a 19-second period and a light offshore from the S. That’s a long period groundswell, and for a reef break like Isla Negra, that could mean some nice, lined-up waves. The energy is moderate (210). It’s still small, but the quality is there.

The real standout is Friday the 14th. Morning has a 5ft swell from the WNW, with a 9-second period and a light offshore from the SSE. The energy is solid (490). But the afternoon is the gem – same swell size, same direction, 9-second period, and a light offshore from the SSE. Energy jumps to 606. The conditions are clean, and the wind is barely there. This is the best session of the whole forecast for clean, fun waves at Isla Negra.

After that, the swell builds again. Saturday the 15th is for the experienced crew. Morning sees a 7ft swell from the W, 11-second period, and a cross-offshore from the S at 16 mph. The energy is very strong (1465). This is getting sizeable, and with the wind, it’ll be a bit wild. The afternoon is 7ft with a 14-second period, but the wind is up to 19 mph. This is expert territory.

Sunday the 16th is still big, with 6ft to 5ft, but the wind is still strong. Monday the 17th morning is a good call – 4ft WSW swell, 11-second period, and a gentle offshore from the S. Clean, fun waves.

The big highlight for the heavy hitters is Wednesday the 19th. Morning has a solid 8ft swell from the WSW, 14-second period, and a cross-offshore from the S at 9 mph. The energy is massive (2438). This is excellent for experienced surfers only. The afternoon is the same size but a bit shorter period. Thursday the 20th is also excellent, with 6ft to 6ft WSW swell, 13-14 second periods, and a gentle cross-offshore. Energy is still strong (1313-1170).

So, the best on offer: Friday the 14th afternoon is the standout for clean, fun, manageable waves. For the big-wave crew, Wednesday the 19th morning is the call, but only if you know what you’re doing. The crowds at Isla Negra can be there sometimes, so keep your head on a swivel.

Rusty out.
