San Juan Surf Forecast and Surf Report

Alright folks, Rusty here. Let's be straight with you – it's a tough stretch ahead for San Juan. We've got a solid run of swell on the cards, but the wind is going to be a persistent problem, making things messy.

Right now, the water's sitting at 73°, which is a touch warmer than usual for this time of year. The issue is the wind. For the next week and a half, it's hammering in from the north-northeast, right onshore, at 18 to 25 mph. That's a fresh to strong breeze, and it's going to tear up the surface. We've got a consistent 7 ft to 8 ft NNE swell running from the 19th of July right through the 23rd, with a short period of 7 to 8 seconds. The combined energy will be moderate, reaching the 400s and 500s, but with that onshore wind, it's going to be a choppy, blown-out mess. The wave comment is spot on: "poor surf conditions." This is a reef break, and with that wind and swell size, it's not looking like a paddle-friendly setup; honestly, this is more of a kite-surfing scenario.

The swell builds through the 25th and 26th, pushing 8 ft with periods stretching to 9 seconds. The combined energy jumps into the 700s and 1000s, showing there's some real power, but the wind sticks to that same nasty NNE direction, still blowing 18-22 mph. It's cleaner, but it's not clean. By the 27th of July, we're looking at a 10 ft NNE swell with a 9-second period and a combined energy of 1269 – that's strong wave energy. However, that's expert territory, and with the wind still on it, it's a raw, heavy, and dangerous proposition.

The only glimmer of hope comes late in the run. On the 29th of July, the wind finally drops to a moderate breeze of 12 mph from the NNE, still onshore, but much lighter. The swell drops to 7 ft from the north with an 8-second period. The 30th and 31st see the swell drop further to 4 ft to 5 ft, and the wind is a bit more manageable. The 31st of July morning has a clean 4 ft swell from the north with a 9-second period and moderate breeze from the north, but by the afternoon it goes cross-onshore. For the first day of August, it's a write-off with fresh cross-onshore winds and lumpy conditions.

The standout here, if you can call it that, is the morning of the 29th of July. The swell is a manageable 7 ft from the north, and the wind is a lighter onshore breeze. It's not great, but it's the best we've got. The 31st of July morning is also worth a look with a clean 4 ft north swell, but it's small. Don't expect much.

To sum it up: we've got a solid 16-day window of swell, but the wind is a curse. It's a long gap of poor conditions until the 29th of July where things might be borderline. We'll call the 29th of July morning the best option, but it's a long way out, so keep your hopes in check.

Rusty.
