Explosivos Surf Forecast and Surf Report

Alright, let’s get real about this stretch. I’ve been combing through the charts for *Explosivos*, and honestly, it’s a bit of a rough start. We’ve got waves right from Friday the 11th of September, but the conditions are a real mixed bag, and nothing’s really screaming “drop everything and go.”

First up, the water temp is sitting at 69°, which is a whopping 8° warmer than usual for this time of year. That’s very unusual – you’re basically getting a tropical bath, so a spring suit or a shorty is all you’ll need.

Friday morning kicks things off with a 6ft south swell, period around 8 seconds. The energy is moderate (775 combined energy), but the wind is coming from the SW at 6 mph, putting it cross-on. It’s light, but it’s not clean. It’s a sandbar break that’s exposed to the swell, and it’s consistent, but the combo of the cross-on breeze and the short period means it’s going to be a little lumpy. The afternoon only gets worse with the wind picking up to 9 mph.

Saturday and Sunday are more of the same: waist-to-chest high swell, but that persistent cross-on wind keeps things from getting good. The energy drops through the weekend, and all the morning sessions are being written off as marginal.

Now, here’s where it gets interesting for the more experienced crew. Around Monday the 14th and Tuesday the 15th, the swell drops in height quite a bit but the period goes massive. Monday morning shows 3ft but the period is a very long 18 seconds from the SW. The combined energy is actually still decent (742), which tells you there’s some deep-water power in the water. This kind of long-period groundswell, over 15 seconds, is going to stand up nicely and look a lot better than the height suggests, but it can close out beach breaks. At a sandbar, it might be tricky, but for an advanced surfer who knows the bank, this could be the gem of the whole forecast. The wind is light and onshore, but light enough that it might glass off. The caveat is that the scores for these sessions are low, so it’s a gamble.

After that, from the 16th through to the 26th, it’s a long slow fade. Swell sizes hover around 3ft to 3ft with periods dropping back below 8 seconds and the wind staying stubbornly cross-on or onshore. The energy readings drop into the 200-500 range, which is weak to moderate. There are days like the 25th where the period jumps back to 20 seconds, but with only 1ft of swell, it’s just not enough to push through. This is essentially a two-week stretch where the real juice is only on the Monday and Tuesday of the first week.

The Pick: For the daring advanced surfer, the morning of Monday the 14th of September and Tuesday the 15th of September offer the most potential. Look for the 3ft to 4ft waves with the very long 15-18 second period from the SW. The wind is light, so it could be cleaner than anything else in this window. But keep in mind it’s a sandbar, so that long period might make it fat. If you can find the right bank, you might score a few proper runners in near-glass. For everyone else, this is a week to check other spots or wait for a better window.

Stay frothy,
Rusty.
