Isla Negra Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for Isla Negra. It’s going to be a bit of a slow burn, but there are some proper windows to get excited about.

Overall, this isn’t a run of non-stop action. There’s a flat spell right out of the gate that lasts the rest of today and into Monday. We’ll see some tiny waves trickle in from Tuesday, but the real juice doesn’t show up until midweek, with the best stuff falling on Wednesday, Thursday and then another solid pulse the following Sunday.

First up, on Sunday morning (July 5th), we’ve got a 4ft swell from the WNW with a short 8 second period – not much energy behind it (131). It’s surfable but nothing special, and the water temp is sitting at about 54°, which is around 3° colder than normal for this time of year, so it’s definitely a bit nippy. By the afternoon, it drops off quickly. Monday is a total write-off, flat as a tack.

We start seeing some movement on Tuesday morning (July 7th) with a 2ft ripple, but the afternoon is where it gets interesting. Tuesday afternoon pulls in a proper groundswell from the WSW with a 13-second period, 3ft, and the energy jumps right up (367). It’s a cross-off wind, so the lines should be clean. This is the warm-up act.

Now, Wednesday (July 8th) is the first true standout. Wednesday morning is glassy, absolutely dead calm, with a solid 5ft swell from the west, 11-second period and a beefy 543 combined energy. That’s a moderate wave energy and the glassy wind will make it look like a mirror. This is prime time for the advanced crew – that size is getting a bit pushy for beginners. The afternoon holds similar quality at 5ft, still glassy. This is the best of the first week.

Thursday (July 9th) backs it up nicely. Morning sees 5ft from the W with 11 seconds, 663 energy, and a cross-off wind. This is still very good, consistent, and clean. A little bigger, a little more power, but still manageable for experienced surfers. Crowds are “sometimes” an issue here at Isla Negra (a reef setup), so you might have some company on these good days.

We cruise through Friday and Saturday with smaller, clean 3ft to 4ft waves – fun but not the highlight.

Then Sunday (July 12th) brings the second standout. Sunday morning delivers a 6ft swell from the WSW, 12-second period, and a whopping 833 combined energy. That’s moderate to strong energy, and it’s the biggest, most powerful swell of the run so far. Cross-off wind keeps it clean. This is a legit session. By Sunday afternoon, it’s still pumping at 6ft.

The following week looks quieter. Monday and Tuesday drop off significantly, with small, weak waves. Wednesday and Thursday (July 15th & 16th) are marginal at best, with some cross-off winds but questionable conditions. Friday evening sees a weird spike in period (17 seconds) but with only 1ft of swell – that’s a super long period groundswell, but not enough height to do much at a beach-reef setup like this. It’ll be inconsistent.

The week closes out with some hope. Sunday (July 19th) morning is offshore with clean 3ft WSW swell (346 energy). The next day, Monday (July 20th) morning, looks *potentially* huge but tricky. There’s an 8ft swell from the WSW on the chart, with a 14-second period and very high combined energy (2668). However, the wind is cross-on, and conditions are flagged as marginal. That’s expert territory only, if it cleans up. Right now, it’s a long-range promise, but that direction at Isla Negra with that size could be wild.

Best bet: Wednesday morning (July 8th) for the glassy perfection, or Sunday morning (July 12th) for the biggest, cleanest power session of the forecast.

Rusty.
