Explosivos Surf Forecast and Surf Report

Alright, let’s talk about what’s cooking at Explosivos.

We’ve got a solid stretch of consistent swell rolling in, no real downtime to start. This is a consistent, exposed sandbar, and it’s grabbing a long-period groundswell from the SSW and SW that’s packing moderate to strong power across much of the forecast. The combined energy numbers are mostly in the hundreds (1248, 1162, etc.) – that’s real grunt behind the waves, and with periods sitting around 14 to 20 seconds, this is proper groundswell with long, powerful lines and nice gaps between sets, making the paddle out a bit easier. The water temp is about average for this time of year, nothing out of the ordinary.

Friday morning (3rd July) kicks things off with a 5ft swell from the SSW, period of 14 seconds, and the wind is onshore from the SW at a light 6 mph. It’s a bit bumpy, but there’s enough push to get into something. The afternoon sees the breeze turn to a light cross-onshore from the south, keeping it a little messy.

Saturday (4th July) drops to about 4ft from the SSW, with a light cross-onshore wind in the morning and a touch of gloss early afternoon – that cross-on breeze from the WSW at 6 mph is borderline, but the swell’s got some legs from the long period.

Now, here’s the real standout: Sunday morning, 5th July. The swell is only around 4ft, but it’s coming from the SW with an incredible 20-second period – that is very long-period groundswell. The combined energy jumps to 1511, which is strong. The wind is a mere 3 mph from the SW, close to glassy, and that’s a huge plus. For a sandbar, that long period can sometimes make it break a bit straight, but with conditions this clean, you’ll get smooth, lined-up waves. Crowds are possible here, so get there early.

Sunday afternoon picks up a bit to 5ft from the SW, period 19 seconds, but the wind strengthens to 9 mph from the south, going cross-shore, kicking up some chop. Still decent, but the morning is the one.

Monday and Tuesday (6th and 7th July) hold the swell around 5ft to 6ft from the SSW, with light onshore winds from the west and WSW. The energy stays strong (2012 on Monday morning), and with those onshore breezes, it’ll be a little ragged but still punchy. That size is fine for most surfers, not too big for intermediates.

From Wednesday (8th July) onward, the swell settles into the 3ft to 4ft range, the period drops to 13-15 seconds, and the wind stays mostly a light cross-onshore from the SSW or south. The energy slides into the 500-900 range – still surfable but nothing to write home about. The mornings with a hint of onshore wind might give you the cleaner lines.

The second week, starting around 11th July, the swell shrinks and the wind is mostly cross-onshore or cross. The energy numbers drop into the 400-800 range. There’s a little bump on the 13th July with 5ft from the SSW and a 15-second period, but the cross-on wind means it won’t be as clean as that Sunday morning. The 12th July afternoon has a 3ft swell with a long 18-second period from the SSW, but the cross-on breeze limits it to a small, clean option.

The Sunday morning, 5th July is your clear best bet – lock it in. The rest of the week is consistent but mostly average, with Monday and Tuesday offering push if you don’t mind the onshore texture. After that, it’s a slow fade into smaller, choppier days.
