San Juan Surf Forecast and Surf Report

Alright, let’s talk about what’s cooking for San Juan over the next couple weeks. Honestly, it’s a slow start. The first few days have some swell, but the wind’s got teeth – it’s spoiling things. There’s a big dry gap in the middle, but we do get a couple clean windows if you pick your day.

First real chance to paddle out is Sunday the 13th. Sunday morning it’s dead calm, glassy as a mirror, with a 5ft swell from the north, period around 8 seconds. Combined energy is moderate, 342. Water temp is about 75°, running a degree warmer than normal for this time of year, so it’s pleasant. The waves will be clean but short-period – a bit walled. Sunday afternoon the wind shifts to a light cross-offshore from the WSW at 6 mph, swell drops a touch to 4ft, but stays clean. That’s your best bet early on. Nothing special, but it’s rideable.

Then we hit a long, frustrating stretch. From Monday the 14th through Saturday the 19th, the wind is strong and onshore or cross-onshore, swell is tiny or messy – mostly under 3ft – and conditions are poor. The combined energy drops into the low hundreds or below. Just not worth suiting up.

Next window opens Sunday the 20th. Sunday morning, we’ve got a clean 4ft north swell with a light cross-off from the WSW at 3 mph. Afternoon is similar, 3ft, cross-off from the west at 6 mph. Combined energy is moderate, around 282 and 242. Small but glassy – good for a longboard.

Now, Monday the 21st is the standout of the whole outlook. Monday morning, a tiny 2ft swell from the NNW, but the period jumps to 11 seconds – real groundswell. Wind is a light cross-off from the SSE at 6 mph. Then Monday afternoon gets even better: swell holds at 2ft from the NNW, but the period stretches to 16 seconds – that’s very long period groundswell. Wind goes glassy, zero. Combined energy is 411, moderate. Those waves will have serious shape and power for the size, with long lulls between sets. Clean, lined up, and worth waiting for.

Tuesday the 22nd still shows a 4ft NNW swell with 13-second period in the morning, but wind goes onshore from the NE at 9 mph – that’ll chop it up. After that, the rest of the week fades – small swell, onshore wind, poor quality. By Friday the 25th we’re down to 2ft and combined energy of 86 – weak.

So here’s the take: your best sessions are Sunday the 13th for clean but short-period waves, and Monday the 21st for the cleanest, longest-period glassy day of the whole run. The rest is a lot of wind and waiting. Two good days in 16 – that’s the hand we’re dealt.

Keep your eyes peeled for that Monday session.
