San Juan Surf Forecast and Surf Report

Alright, Rusty here, let's talk surf for San Juan.

Alright, folks, I'm gonna be straight with you – this San Juan forecast is a tough pill to swallow. We're looking at a solid 16-day run, but don't get excited, because for the next week and a half, it’s all about raw, onshore, choppy conditions. There isn't a single standout day in the near future. The wind is coming from the north and northeast, smashing that open reef. It's mostly a "moderate breeze" but cranking up to a "fresh breeze" often enough, and it is relentless. We're looking at a long stretch of "poor surf conditions" with zero scores across the board.

Through the first week of July, from Monday the 6th right through to Saturday the 11th, the swell is tiny – we're talking 2ft to 4ft – with short, weak periods around 5 to 8 seconds. The combined energy is low, mostly two-digit numbers (39 to 93), which is basically nothing. The wind is cross-onshore or even straight onshore, making for chop and mess. It's not surfable.

We see a slight bump in energy from Sunday the 12th onwards, with the combined energy jumping into the 100s and 200s (186 to 289), and even hitting 300s and 400s later on. The swell height creeps up, hitting 5ft on the 16th, and then ramps up to 7ft by Friday the 17th. But here’s the kicker – the wind remains "on" from the north or northeast at 16 to 22 mph, blowing directly onto the reef. The period stays short, mostly 6 to 8 seconds, making for that awful, walled-up, onshore junk. This is heavy, messy, and dangerous for all but the most experienced. With the swell topping 8ft on the 19th of July, it's strictly expert territory, and even then, it's going to be a brutal, wind-affected wall.

For the one and only break, San Juan (a reef), it's an expert-only wave when it's good, but with the onshore wind and the swell direction (NNE, N) being the exact opposite of the optimum (NNW), it's gonna be a washing machine. The water temp anomaly is listed as "-", so it's average for the time of year. There is simply nothing to recommend for a paddle surfer. Honestly, this kind of strong, onshore wind with a solid, messy swell on a beach or reef setup might be more interesting for the kite crew than anyone with a surfboard. The blank run stretches from the start, right through the entire 16-day window. No standout. No hope. Keep the board in the car for the next swell direction change.

Stay patient.
Rusty.
