Explosivos Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s on the cards for Explosivos over the next couple of weeks.

The setup is a bit of a slow burner. We’re starting off with some solid swell energy, but the conditions are holding it back from being a real standout right now. The water temperature is 69°, which is a whopping 7° warmer than normal for this time of year – that’s very unusual and honestly feels a bit tropical out there for a late August stretch.

First proper recommendation shows up on Saturday the 29th of August. The swell is running a decent 6ft out of the SW, with 14-second periods and a combined energy of 1164, which is strong energy. Unfortunately, the wind is coming from the south at 6 mph, so we've got light cross-onshore conditions. It’s not howling, but it’s putting a bit of texture on the surface. It’s surfable, but it’s not the cleanest. The crowds can turn up here sometimes, so keep that in mind if you’re hoping for a peaceful session. This one’s a sandbar, consistent, and rated for advanced surfers.

Sunday the 30th is pretty similar with a 6ft SW swell and light cross-shore winds, but the energy drops a touch to 985. Not a bad morning if you need a paddle, but it’s still not glassy.

Then we hit a lull. Monday the 31st through to Wednesday the 2nd of September, the swell drops under 3ft, and the conditions are pretty marginal. You could probably find a ripple, but it’s not going to get your heart racing. That gap lasts a good three days where there’s not much worth chasing.

Things start to look up on Thursday the 3rd of September. The swell bumps back up to 4ft, but here’s the kicker – the period jumps to 17 seconds, giving us a true groundswell. The combined energy is back over 1000 (1065), and the wind stays light and cross-onshore. That long period will make the waves a bit more lined up and powerful, but at a sandbar like Explosivos, this kind of long-period SW swell can sometimes be a bit tricky – it might stand up and then close out. Still, it’s a step in the right direction.

The real standout window, if you can wait, is Friday the 4th of September. We’ve got a solid 6 to 6ft SW swell, with a period around 15-16 seconds, and the combined energy hits a strong 1468. The wind is light out of the SSW, so it’s cross-on again but very light. This is the biggest and most energetic swell of the whole outlook. The waves will have some punch, but at 6ft, it’s starting to get a bit chunky for beginners – this is more for the experienced lot. The crowds might be a factor here, as this is the closest thing to a proper groundswell pulse in the forecast.

After that, the swell slowly fades through the 5th and 6th of September, with the energy dropping and the wind picking up a little on the 6th, getting a bit choppier.

There’s a little blip on the 8th of September with a 4ft SW swell and 15-second period, but nothing that truly demands you drop everything.

The final real mention is way out on Saturday the 12th and Sunday the 13th of September. The swell bumps back up to 6-6ft, but the period is short – only 8 seconds. That’s windswell. The wind also picks up to 9-12 mph out of the south, so it’s going to be pretty choppy. Honestly, with that short period and the onshore kick, it looks more interesting for kite surfing than a proper paddle in.

So, the best bet is the Friday the 4th of September session. It’s the biggest, most energetic swell of the whole run, with light winds. It’s not perfect, but it’s the closest thing to a standout in this 16 day window. If you’re after something sooner, Saturday the 29th of August is your next best option.

Stay salty.
Rusty.
