Isla Negra Surf Forecast and Surf Report

Alright, Rusty here again. Let’s break down the same stretch but in feet and miles per hour.

For Isla Negra, the water temp is sitting right around normal for the season, about 55°F, nothing wild.

Monday the 20th is a wash. The swell is only about 3ft from the west, but the wind is a cross/onshore breeze and the waves are messy. The combined energy is weak (293). Not worth the paddle.

Tuesday the 21st is a total mess. A strong, gusty NNE wind blowing near 28 mph, and the swell jumps to 8ft but it’s short-period, onshore junk. The energy is moderate (792) but the quality is terrible. Stay on the beach.

Wednesday the 22nd is the first real bright spot. The morning is glassy, with a clean 6ft swell from the WNW. The energy is solid (783) and the wind is nearly dead. This is a proper standout session – clean, lined up, and the reef will be working. The afternoon is even better, glassy again with 6ft from the west and a combined energy of 843. This is the best of the first week.

Thursday the 23rd stays clean with a glassy morning, though the swell drops to 4ft. The energy is moderate (397) but the conditions are still pristine. The afternoon stays clean with a cross-off breeze and 4ft. Good for a log.

Friday the 24th is another standout. The morning offers a clean 6ft from the WSW with a light offshore wind and a combined energy of 968. The waves will have good shape. The afternoon is similar, with 6ft and clean conditions. Quality surf.

Saturday the 25th is smaller, around 4ft, with clean conditions. The energy is moderate (475). It’s a fun, cruisy morning, not a standout.

Sunday the 26th is a dud. The swell is small, 2ft, and the wind is onshore or cross-onshore. The energy is moderate (632) but the quality is marginal.

Now, Monday the 27th is the big one. The morning brings a solid 7ft west swell with a 12-second period and a light cross-off breeze. The combined energy is a massive 1735 – strong, powerful. This is for experienced surfers only. The reef will handle it beautifully. The afternoon is nearly as good, with 6ft and a clean offshore wind. This is the top of the run.

Tuesday the 28th holds the size, with 6ft from the WSW and a 13-second period. The morning has an onshore breeze, so it’s a bit lumpy, but the afternoon cleans up with a glassy cross-off and excellent energy (1069). Another day for the experienced crew.

Wednesday the 29th is still good, with 6ft and a clean offshore wind. The energy is strong (931). The waves will be well-formed.

Thursday the 30th sees a drop-off. The swell dries up to 3ft and a moderate onshore breeze ruins the shape. The energy is only 262 and the quality is poor.

Friday the 31st is a total write-off. Heavy rain and a strong 28 mph onshore wind, with 8ft of messy, blown-out swell. The energy is high (1842) but it’s unsurfable. Kite surfers might like it, but paddle surfers should stay home.

Into August, Saturday the 1st is marginal. The swell is 6ft but the wind is onshore. The energy is moderate (905) but the quality is poor.

Sunday the 2nd morning is a late standout. A glassy 7ft west swell with a 12-second period and a combined energy of 1413. This is a powerful, clean morning for experienced surfers only. The afternoon turns ugly with a strong onshore wind.

The rest of the run into Monday the 3rd and Tuesday the 4th is a letdown. Small swell, onshore winds, and poor energy. It’s a quiet end.

So, the best windows are Wednesday the 22nd, Friday the 24th, and the absolute highlight is Monday the 27th and Tuesday the 28th. The 2nd of August morning is also a late, powerful option. Get on it while it’s clean.

Rusty.
