San Juan Surf Forecast and Surf Report

Alright, this is Rusty comin' to you live from the coast. Let’s be real with you right off the bat: the next two weeks here are a tough watch. We’ve got a hefty stretch of "poor surf conditions" stamped all over the forecast, and the numbers back it up. There’s no standout session, no hidden gem, nothing to get genuinely excited about. It’s a long, frustrating run of onshore winds and messy, short-period chop.

The whole show is pinned on the exposed reef at San Juan. It’s a consistent, expert-only wave that needs a clean, lined-up swell from the NNW to really fire. Instead, we’re getting wind from the north and northeast, hammering the surface, and the swell is a short, weak, wind-driven N to NNE thing. The combined wave energy barely cracks three digits, only just reaching a moderate 168 (m) on the first afternoon, and it struggles to build from there.

We start Tuesday afternoon, August 11th, with a 5 ft north-northeast swell, but it’s only 6 seconds of period. The water is 74° here, feeling a touch warmer than normal for this time of year. But that wind is a fresh 19 mph, straight onshore, and it’s just a mess. By Wednesday, the swell is a bit bigger but the wind is still ruining it. This pattern holds through the entire first week. The waves are small, under 6 ft, the period is short, and the wind never lets up. It’s a frustrating stretch of days.

Looking into the second week, things don't get better for us. The swell picks up a bit, hitting 6 ft on Friday, August 21st, with moderate energy (514 m), but the period is still a weak 8 seconds, and the wind is a fresh onshore breeze. By Saturday, August 22nd, we’re looking at a 7 ft north swell, but it’s still a 6-7 second windswell, hammered by 22 mph onshore winds. The combined energy finally climbs to a moderate 677 (m), but the surf quality is "poor" and "lumpy." It’s pure grunt. For an expert reef, that’s just a washing machine. For anyone else, it’s dangerous and not fun. The last few days of the outlook just fade out with dropping swell and relentless wind.

Honestly, for the next two weeks at San Juan, you’re better off leaving the boards in the car. The wind is wrong, the swell is weak and short, and the conditions are consistently poor. The setup looks more interesting for kite surfing than paddle surfing. It’s a real bummer, but sometimes the forecast is just a blank. We’ll keep an eye on it, but for now, this is a hard pass.
