Costa Azul Surf Forecast and Surf Report

Alright, let’s talk about Costa Azul. This stretch has a solid run of surf across the 16-day window, but there’s a quiet patch right at the start. Wednesday afternoon the 9th is a no-go—marginal conditions with a light cross breeze and just enough energy to tease you. Nothing worth paddling out for.

But from Thursday morning the 10th, it starts turning on. That morning is the real standout of the first week. Glassy surface, light air from the NNW, and a clean 4ft SW groundswell pushing in at 16 seconds. That’s proper long-period energy, so expect good shape and long gaps between sets—makes getting out the back a bit easier. The combined swell energy is solidly moderate at 803. This is the best you’ll see in the early run. Afternoon goes a bit lumpy with a cross breeze, so make the morning session count.

Friday the 11th dawns glassy again with zero wind—absolutely dead calm. Swell drops a hair to 4ft, but that 15-second period still has push. The energy’s down to 525, but it’s clean and offshore by the afternoon. Good surf, for sure.

Saturday and Sunday the 12th and 13th stay clean. Swell eases to 3ft then 2ft, but the wind stays light and mostly offshore or glassy. Not big, but fun little waves with no crowd stress. Costa Azul is very consistent and exposed to the SSE—when it’s small, the inside banks can still offer rides.

Monday the 14th is a write-off. Onshore wind, messy chop, and poor surf. Skip it.

Then Tuesday the 15th morning greets you with clean conditions again—2ft but with a long 18-second pulse. The energy jumps back up to 532. For such a small height, that period means it’ll have more push than you’d think. Wednesday the 16th through Thursday the 17th pull together a nice run: glassy mornings, clean afternoons, 3ft to 4ft swell, consistent 14 to 16-second periods, and energy sitting in the 600 to 745 range. These are your solid mid-range days.

Come Friday the 18th into the weekend, the swell hangs around 3ft to 3ft, but the period stretches back to 18–19 seconds. The late-afternoon sessions on the 19th and 20th are clean with offshore or cross-off wind, but the morning of the 20th has a bit of a cross breeze. Energy climbs to 945 on the 20th—that’s the highest of the whole run, moderate but getting towards strong.

The final week, from Monday the 21st through Wednesday the 23rd, is gorgeous. Glassy conditions, light air, morning after morning of 3ft to 4ft SW swell at 15–17 seconds, and clean offshore or glassy wind. Energy numbers stay between 713 and 905. These are your true standouts for the second week—steady, clean, and fun.

Thursday the 24th winds it down with smaller 3ft swell and a lighter period, but still glassy in the afternoon.

Water temp here is sitting at 87°F, which is 5°F warmer than average—that’s notably warm for this time of year. Feels like a bath, but in a good way.

Overall, don’t bother with the 9th. The best on offer is Thursday morning the 10th for the first week, and then Monday to Wednesday the 21st–23rd for the second week—those morning glass-offs with that long SW groundswell are money. Crowds are possible at Costa Azul, but with conditions this good, you might see a few more heads out. Still, it’s worth it.

This is Rusty, signing off.
