Acapulquito-Costa Azul Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming up for us at Acapulquito-Costa Azul.

Right off the bat, this isn’t a classic week. The first few days are a write-off for quality surfing. We’ve got a big, powerful swell rolling in on Wednesday 2nd September with a solid 10ft face from the south and a very strong combined swell energy (3149), but it’s arriving with a cross-onshore wind and the notes say it’s marginal. That’s a messy, choppy mess, and at that size, it’s really only for the experts who don’t mind battling the wind.

Water temperature is sitting at 88°, which is a whopping 5° warmer than normal for this time of year – that’s very unusual, so don’t expect to need a thick wetsuit.

That big energy fades down through Thursday and Friday, but the wind stays tricky – mostly onshore or cross-onshore. The swell drops from 8ft down to 7ft but the conditions are still described as poor to marginal. Not our time yet.

The first real glimmer of hope shows up on Saturday afternoon, 5th September. The swell settles to a clean 4ft from the SSW, but the real story is that long-period groundswell at 15 seconds. That kind of period means proper shaped waves, with good energy and longer waits between sets. Combined energy is still solid (1331), and the wind swings to a light cross-offshore breeze, cleaning things right up. It’s an excellent window for experienced surfers.

Sunday 6th September keeps the trend alive. Morning is a bit cloudy with light southerly winds and 5ft swell, but the standout is Sunday afternoon: 5ft from the WSW, 12-second period, with a cross-offshore breeze giving us clean waves. Very good conditions for those who know what they’re doing.

By Monday 7th September morning, we finally get a pure offshore wind from the NNW, with 5ft swell from the WSW. It’s a bit smaller, but clean and organised. This is a solid session for an intermediate surfer who doesn’t need huge waves, just good shape.

Tuesday 8th September offers more of the same – clean offshore winds in the morning, with 4ft swell, and the afternoon stays clean, though the swell drops to 3ft. It’s consistent and fun, if not epic.

Now, for a heads-up: Wednesday 9th September looks weird. The swell period jumps to a massive 17 seconds, but the swell height is only 3ft and the wind cranks up to a strong 28 mph from the west. That’s a gale, and with that low energy (747) and that much wind, the ocean is going to be blown-out and nasty. It’s a kite-surfing kind of day, not a paddle day.

The second week, from around 11th September onward, is much smaller. We get glassy, clean conditions from the 11th through the 13th, with the swell sitting between 3ft and 3ft, and the period staying very long (14 to 19 seconds). That long period will make the waves at Acapulquito-Costa Azul (a beach-and-reef setup) a bit straight and fat, but the glassy surface is a treat. Good for a log or a fun shape.

The real standout of the entire 16-day run? I’d pick Saturday 5th September afternoon. That combo of 4ft groundswell, 15-second period, and a light cross-offshore wind is the cleanest, most powerful session on offer. The energy is still solid, and the conditions are described as excellent for experienced surfers. That’s your go.

The last few days, from the 14th to the 17th, are tiny (2ft to 3ft) but glassy. If you’ve got a longboard and patience, there’s something there, but don’t expect to get your chest wet.

Overall, the first weekend is the window. After that, it’s a slow fade into summer lull.

Stay stoked,
Rusty
