The Rock-Costa Azul Surf Forecast and Surf Report

Alright folks, Rusty here with the long-range look for your local stretch.

We’ve got a solid run of surf coming our way starting this Sunday morning and it’s looking like a good stretch for the region. The water is sitting at 88.9°, which is a whopping 6.5° warmer than normal for this time of year. That’s very unusual and is a real treat for a late-season session. You'll feel like you’re surfing in the tropics.

The real standout of the whole forecast is Wednesday the 16th. Early morning we’re looking at a clean 3.6 ft of SSW groundswell, with a period around 16 seconds and a combined energy of 673 (moderate wave energy). But the real kicker? Glassy conditions with barely a breath of wind from the SSE at 3.1 mph. That’s going to be pristine. This is a reef break (The Rock-Costa Azul), and that long-period swell loves a setup like that, wrapping in nicely. It’s a consistent wave here, but a bit of a heavy one – it’s rated advanced, so this is for the crew who know what they’re doing. Crowds are often around, so expect company for the good ones.

Let’s walk through it day by day.

Sunday 13th September: We kick off Sunday morning with clean 2.3 ft from the SW, 13-second period, combined energy of 321 (weak to moderate) and glassy 3.1 mph S wind. A nice easy start. The afternoon sees a small drop in size to 1.6 ft, with a very long 19-second period, but the wind shifts to a 9.3 mph cross-offshore from the W. It’s clean but a bit small.

Monday 14th September: Another glassy morning with 2.3 ft of SW swell at 18 seconds (408 energy). Good, clean conditions with 3.1 mph WSW winds. The afternoon is a little smaller at 2.0 ft but still clean with cross-offshore winds. A good consistent run.

Tuesday 15th September: The morning is a little messy with a cross-shore wind from the NE at 6.2 mph and 2.0 ft. Not the one. But the afternoon? That’s a real highlight. The swell picks up to 2.3 ft SW, 16-second period, and the energy jumps to 566. The wind goes glassy again with 3.1 mph WSW. The report says "very good surf conditions" and I agree. This is the other standout session in the first week.

Wednesday 16th September: As I said, Wednesday morning is the pick of the whole run. 3.6 ft of SSW groundswell, 16-second period, combined energy of 673, and glassy conditions with 3.1 mph SSE winds. The afternoon holds at 3.6 ft but drops to a 15-second period and picks up a 6.2 mph cross-offshore breeze. Still clean, but the morning is the magic window.

Thursday 17th September: Solid again. 3.3 ft SSW swell at 14 seconds, combined energy of 754 (moderate to strong). Glassy morning with 3.1 mph SSW winds. The afternoon is clean but slightly stronger cross-offshore breeze. Both sessions look very good.

Friday 18th September: A slight dip. Morning sees 2.6 ft but the period is a nice 19 seconds. The combined energy is a solid 783. However, the wind is light cross-shore from the S, putting a bit of texture on it. The afternoon is cleaner with 2.3 ft and cross-offshore winds.

Saturday 19th September: A good start to the weekend. 3.0 ft SW swell at 18 seconds (627 energy) and glassy S winds in the morning. The afternoon has a risk of thunderstorms and a stronger cross-offshore breeze, but the morning looks sweet.

Sunday 20th September: More of the same goodness. 3.3 ft SW swell, 17-second period, combined energy of 725, and a glassy start with 3.1 mph SW winds. Afternoon holds with clean cross-offshore winds.

Monday 21st September: This is the peak of the second window. The morning hits 3.9 ft of SW swell at 17 seconds with a combined energy of 962 (getting into the strong range). Glassy with 3.1 mph WSW winds. The afternoon is just as good – 3.6 ft and totally glassy with zero wind from the WNW. That is an incredibly clean afternoon session.

Tuesday 22nd September: Still solid
