The Lowdown
Alright, let’s break it down for the next couple of weeks here at Playa de Gaztetape. It’s a bit of a slow start, but there’s some real juice coming down the pipe later on. Water temp is a warm 77 degrees, which is about 6 degrees above the norm for this time of year—that’s a whole lot warmer than usual.
The first few days are pretty flat and weak. Sunday the 16th has some small waves around 3 feet from the northwest, but the energy is weak, down around 78. It’s glassy in the morning, but there’s just not enough push. Monday and Tuesday are much the same—tiny, weak, and not worth the paddle. We’re looking at a few days of nothing much.
Thursday the 20th is the first flicker of hope. The swell is still small, around 3 feet, but the period jumps to 11 seconds and the energy climbs to 177. It’s still not great, but with glassy morning conditions, it’s the first real option.
Friday the 21st is when things start to get interesting. Swell bumps up to 5 feet from the northwest, with a 10-second period. The combined energy jumps way up to 440. The wind is light and cross-on from the northeast, which isn't perfect, but the size is building.
After a quieter weekend, the big one arrives on Monday the 24th. The swell builds big through the day, and by the afternoon, we’re looking at a serious 12 feet from the west-northwest. The energy is a massive 1867, which is a lot of water moving. The wind is light and cross-off, and it’s forecast to be clean. But at this size, this is for experienced surfers only. It’s too big for anyone else, plain and simple.
Tuesday the 25th is the other standout. The swell eases to a still-chunky 7 feet from the northwest, with energy at a strong 753. Morning winds are light and cross-off from the southwest, which should keep it clean. This is probably the pick of the window for the average good surfer—solid size, good energy, and clean conditions.
After that, it fades away quickly. The rest of that week and the start of September look small and weak, with no real energy. The last sliver of hope is around the 30th, but that’s over a week away and confidence is low.
So, get your plans sorted for the 24th if you’re an expert, or the 25th for everyone else. That’s where it’s at.
