San Juan Surf Forecast and Surf Report

Grab a coffee, sit down. Let’s talk about the next couple of weeks at San Juan. This is a reef break, exclusively for experts, and it’s consistent – but don’t get your hopes up too much right now. The entire 16-day window is a bit of a struggle. We start with a solid first swell, but the wind is a real problem. The water temp is sitting at 70°, which is about average for this time of year, nothing unusual.

The first real chance you’ll get is on Friday afternoon, July 3rd. The wind is a light cross from the WNW at 6 mph, and we’ve got a north swell at 5 ft coming in with a 10-second period. The combined energy is moderate (431). It’s marginal, but it’s the best we’ll see for a while. The cross-shore wind will keep it from being perfect, but it’s your only shot, and it’s a reef break, so it’ll hold shape.

Then, from Saturday morning, July 4th, all the way through to Sunday, July 12th, it’s a total write-off. The wind is cross-on, onshore, or just too strong – hitting 19 mph on the 11th and 12th. Swell drops to 2 ft to 4 ft, with short periods around 5-8 seconds. The energy is weak, often under 100 or just barely into the low hundreds. It’s choppy, messy, and not worth paddling out for. That’s a solid nine days of nothing.

Things try to get going again from Monday, July 13th. The swell picks up to 5 ft to 5 ft, and the period lengthens to 8-10 seconds, with energy climbing back into the 200-700 range. But the wind remains a hard onshore from the NNE or N at 16-22 mph. It’s a strong breeze, and the waves will be blown out. The “poor surf conditions” tag is on every single session. This is the kind of setup that looks more interesting for kite surfing than paddle surfing.

The final few days, from Thursday, July 16th to Saturday, July 18th, the swell drops back to 3 ft to 4 ft, period shortens to 5-9 seconds, and the wind is still onshore or cross-on at 12-22 mph. Energy is weak to moderate.

The only standout here is Friday afternoon, July 3rd, and even that’s a “marginal” call. If you absolutely have to get wet, go then. The rest of the window is a hard pass. The reef is there, but the wind is just not cooperating.
