San Juan Surf Forecast and Surf Report

Alright, let’s get real about the outlook. It’s a bit of a grim picture out there for the next couple of weeks, so let’s just get into it.

The Overall Picture

Honestly, this stretch is looking flat and pretty uninspiring. We’ve got a real gap of poor conditions ahead. Looking at San Juan (La Union), the first day on offer, Monday the 10th, has a bit of swell, but it’s tangled up with stormy weather and the conditions are too marginal to get excited about. After that, we’re looking at a long stretch of tiny, weak surf that just isn’t going to be worth the paddle. There’s a solid run of days where the swell drops right off. The energy is just gone. We’re talking about a gap that runs for more than a week where there are simply no good recommendations at all.

The Start: Monday, August 10th

We’ll see a modest bump of swell on Monday morning. It’s reading around 7ft at 9 seconds, straight out of the west. That’s a bit of a short-period wind swell, so it’ll be a bit on the messy side. The energy is moderate at 667. With a moderate cross-offshore breeze from the SSW, the waves will be clean but stormy skies and the risk of thunderstorms put a real downer on it. The water temp is 86°, which is about average for this time of year, so you don't need a thick suit.

The Long Flat Spell (August 11th – 24th)

From Tuesday the 11th, the swell just collapses. We’re looking at tiny 0.7ft to 2ft leftovers with weak periods, and the energy drops into single digits and double digits. It’s not a good look. There are onshore and cross-offshore breezes, with moderate winds at times. This is a classic blank run for the area, and it happens. The promising thing is that San Juan can be inconsistent, so this kind of dead stretch isn't unheard of. But it still sucks when you're watching the forecast.

The only small blip is on Monday the 24th at 2:00 PM, when we get a glassy moment with a west swell at 2ft. But even then, the period is short at only 8 seconds, and the energy is still weak at 58. It’s not enough to get anyone out of bed.

The Tail End (August 25th)

The last day in the window, the 25th, is still flat, with a small 1ft WNW swell and weak energy of 36. It’s more of the same.

So, all in all, there is nothing here that stands out as a true standout. The only session with size is the first one on Monday the 10th, but it’s compromised by storms and only a fair-to-middling swell. If you’re desperate, it’s the best on offer, but I wouldn't get my hopes up. Otherwise, this is a great time to catch up on board repairs or go for a drive.

This is Rusty, signing off.
