The Lowdown
Alright, let's talk about Playa de Gros in the good old imperial system.
Honestly, mate, it's a bit of a slow start. We're looking at a pretty flat spell for the first week and a half or so. From Saturday the 18th right through to the morning of Monday the 27th of July, the swell is just too small and weak to bother with. The wave energy is hanging around the 10 to 350 mark (weak to moderate), with heights barely scraping 0.7ft to 6ft, and the periods are short, under 8 seconds. The wind is mostly onshore or cross-onshore, making it even messier. You'd be better off doing something else.
Now, things start to get a bit more interesting towards the end of the month. The first real standout window is the morning of Wednesday, the 29th of July. The swell is picking up to a clean 6ft out of the NW, with a period of 11 seconds – that's a proper groundswell. The energy is strong at 663 (moderate to strong), and the wind is glassy off the N. It'll be clean, but that size is getting into the territory where beginners might find it a handful. The NW direction is a good match for the spot's optimum.
Then, the following morning, Thursday the 30th of July, is also worth a look. The swell drops back to 4ft from the NW, but the period is still a solid 10 seconds, and you've got another glassy morning with 5 km/h NW wind. The energy is a bit lower at 236 (moderate), but it'll be a much more manageable size for everyone, and the quality will be there.
The rest of the period after that fades back into the small stuff, with the odd marginal session on the 31st of July and the 1st of August, but nothing to get excited about.
So, the pick of the week is clear: the early session on the 29th of July for the biggest and most powerful swell, or the 30th of July for a slightly smaller, more user-friendly wave. Both mornings are glassy, so bring your best board.
Stay stoked,
Rusty
