The Lowdown

Alright folks, Rusty here. Gotta be straight with you – the next couple of weeks are looking pretty grim for a paddle. We're in for a long, flat spell.

Let's start with the here and now. The water temp is sitting at 81°F, which is running much warmer than normal for this time of year, so at least it'll be a warm wait.

For Friday the 17th and right through the next couple of weeks, it's a desert. We're looking at tiny dribbles of swell, mostly under 2 ft, and the wind is almost always onshore or cross-onshore, putting a chop on whatever little bump there is. The combined swell energy is barely registering – mostly single or double digits – so there's just no power in the water. This is a solid stretch of flatness with no real surf on offer until the very end of the period.

Now, there is a glimmer way out there. On Saturday, August 1st, things start to change. The morning looks promising. We've got a 5 ft swell rolling in from the east with a period of 7 seconds. The combined energy jumps up to 402 (moderate wave energy) and the wind is swinging offshore from the NNW. That's the standout window. Playa de San Juan is a beach and reef setup, so with that 5 ft swell and clean offshore wind, it could actually offer some fun, crumbly waves. It's a beginner-friendly spot, so that size is perfect for a longboard or a funboard. Just keep in mind, the swell period is a short 7 seconds, so it'll be a bit soft and lumpy, not the heaving stuff. The afternoon sees the wind turn onshore and the swell drops a bit, so the morning is the move.

Before that, the only other day that even gets a mention is the 31st of July, with a 3 ft swell in the afternoon, but it's cross-onshore, so expect bumpy, small waves.

So, the long and short of it: slog through the flatness until the morning of August 1st. That's your one real shot. It's a long way off, so don't get your hopes too high just yet, but it's the only thing on the menu worth talking about.

Rusty.
