San Juan Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s break down what’s coming for San Juan. I’ll keep it real—this whole 16-day stretch is a tough one. There’s no good surf to get excited about, thanks to relentless onshore winds. No standout days, no hidden gems.

From Tuesday, July 14th, all the way through Wednesday, July 29th, we’ve got a steady strong breeze out of the NNE, mostly onshore, sometimes hitting 25 mph. This keeps the waves lumpy and messy, even when the swell tries to build. The water is about 73°, which is a touch warmer than normal for this time of year, but that doesn’t matter when the surf is blown out.

The first few days are small. Tuesday the 14th shows a weak 3 ft swell from the NNW with a short period of 8 seconds and very low energy. The wind is onshore from the NE at 12 mph, making it a no-go. Wednesday the 15th isn’t any better, with a 4 ft windswell from the NE and a fresh breeze ruining it.

By Thursday the 16th, the swell builds to 6 ft from the NNE on Thursday morning, but that onshore wind at 19 mph keeps it messy. The energy climbs to moderate levels, but the quality is poor. This pattern continues through the weekend. By Saturday the 18th, we’re seeing 7 ft swells from the NNE with moderate energy, but still that onshore NNE wind at 22 mph. It’s getting bigger, but it’s not getting better.

The biggest pulse comes around Wednesday, July 22nd, with a 7 ft swell from the NNE, a period of 8 seconds, and strong energy. But again, the wind is onshore at 22 mph, and by the afternoon it turns cross-onshore and messy. This swell is too big for beginners and, with the onshore wind, it’s only for experts looking for a beatdown.

We see a similar story on Saturday, July 25th, with a 7 ft NNE swell and the highest energy of the whole run. Still, onshore winds at 19 mph keep it from being clean. The last few days, from the 27th to the 29th, the swell drops but the wind stays strong onshore, so there’s no recovery.

In short, this is a rough run for San Juan. The constant onshore winds kill any chance of quality surf. If you’re desperate, the biggest days around the 22nd and 25th of July might offer some power for expert paddlers, but don’t expect anything clean. The setup looks more interesting for kite surfing than paddle surfing with these conditions. Nothing to get excited about here. Forecasts can change, but as it stands, it’s a long wait.

Rusty.
