Explosivos Surf Forecast and Surf Report

Alright, let’s get into it. This is Explosivos, a sandbar setup that’s an advanced wave, and it’s consistent. Upfront, the water temp is running 70° with a massive anomaly of 8° warmer than normal – that’s way outside the usual range, so it’s gonna feel like a bath out there.

We kick off Friday morning, August 14, with some clouds and a south wind 9 mph. Swell is 5 ft out of the southwest with a 16-second period. That’s a long-period groundswell – plenty of energy in the water (combined energy at 1355). But the wind is cross, so there’s a slight cross-chop messing with the face. It’s surfable, but it’s marginal. The best of the first week lands on Friday morning, and even then, it’s just okay.

Through the weekend, the swell drops off a bit – Saturday and Sunday both sit around 4 ft, with cross-onshore winds and light breezes that keep the surface bumpy. Combined energy drops into the 600–800 range. By Sunday afternoon, the wave comment says “poor surf conditions,” and it stays that way. Monday is similar, with 4–4 ft swell and gentle cross-shore wind. The first few days are a grind.

Tuesday morning, August 18, things jump up to 7 ft, then 8 ft by afternoon, with a 14-second period from the SSW. Combined energy spikes to 2594 and 1921. That’s a lot of power. But the wind is moderate cross-shore, and the wave comment says the swell is predicted to be too big for this break. For an advanced spot, that’s a proper warning – it’s gonna be heavy and maybe unruly.

Wednesday, August 19, is still big – 7 ft in the morning, 8 ft in the afternoon, but the period drops to 10 seconds, then 9 seconds. That’s shorter, peaky, less organised. The energy is still high (1810 and 1011), but the comment again says it’s too big for the break. If you’re a solid expert, maybe you paddle out, but it’s not the best window.

Thursday morning, August 20, shows a clean offshore wind from the WSW at 6 mph, with a 7 ft south swell at 9 seconds. That’s the first real offshore wind we’ve seen. The wave comment is still marginal, though. Afternoon turns clear with a light cross-onshore and 6 ft. Not bad, but not magic.

From Friday, August 21, onward, the swell drops to 4 ft then 4 ft, and the period shortens to 8 seconds. Combined energy falls to 390. The wind is light offshore in the morning, then cross-onshore in the afternoon. It’s small, weak, and marginal. This pattern holds through the rest of the second week – swell sizes between 2 ft and 5 ft, periods up to 17 seconds for a brief moment, but with cross-onshore winds and poor or marginal wave comments. The energy stays low, mostly under 600.

The standout moment is really Friday morning, August 14 – the best swell height (5 ft), longest period (16 seconds), and strongest energy (1355) in the first week, even with the cross wind. After that, Tuesday morning’s 7 ft and Thursday morning’s offshore wind are worth a look, but the break is reportedly too big for those bigger swells. For the rest of the 16 days, it’s a lot of small, onshore, marginal surf. The second week is a flat, quiet run.
