San Juan Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a proper look at what’s cooking for San Juan over the next couple of weeks. Gotta be straight with you – this is a tough one to call. The whole 16-day window is a write-off for decent waves. From now all the way through to July 30th, every single surf report is marked as "poor surf conditions" with a score of zero. That’s a solid two-week gap with no surf worth chasing. The wind is relentless, blowing straight onshore from the north and north-northeast every day, often a fresh breeze of 18 to 25 mph, which is just going to chop everything to bits. There is swell coming through – it’s not totally flat – but when the wind is this bad, it doesn’t matter.

The only wave that even gets mentioned is San Juan, a reef break rated for experts only, and it’s consistent. It faces the optimum swell direction from the NNW, but the swell that’s arriving is mostly from the north and NNE, so that’s not ideal. The water temperature is 73°, which is about a touch warmer than normal for the time of year – not a major anomaly, just a little extra warmth.

Through the second week, especially around July 22nd and 23rd, the swell actually builds to a solid 7 ft to 7 ft, with combined energy climbing into the moderate-to-strong range (506 to 552). But even then, the wind is onshore or even cross-onshore by the afternoon of the 22nd, making it messy. Short period swell, mostly around 7 to 8 seconds, so it’s windswell – weak, bumpy, and unappealing.

Honestly, with that much wind and that kind of swell hitting an exposed reef straight on, this setup looks more interesting for kite surfing than paddle surfing. There’s no standout moment here. Sometimes a blank stretch like this is just what the area does, and we have to wait for the pattern to shift. Forecasts can change, but right now, save your energy and leave the board in the car.

Rusty.
