Passe de L'Ambulante Surf Forecast and Surf Report

Yo, Rusty here. Let's break down what's coming up for Passe de L'Ambulante. We've got a solid run of swell ahead, but you're gonna need to pick your moments.

The window kicks off on Sunday, the 13th of September, with a clean 6ft SSW swell rolling in, but it's cross-offshore with a 25 km/h SE wind, keeping things a bit lumpy. The water is a touch warmer than normal at 76°. The combined energy is pumping at 2072 (moderate-strong), and those 16-second periods mean proper groundswell. It's a reef break and very consistent, exposed to the swell, and the direction is a bit off the optimum SW. It's rideable, but not the best of the window.

Monday the 14th sees the swell size hanging in the 6-6ft range with a similar cross-off wind, and the energy drops a bit. Still clean, but marginal.

Now, here's where it gets interesting. On Tuesday the 15th of September, the wind cranks offshore from the SE at 25-28 mph. Yes, it's strong, making it clean but a real battle to get out. Swell is 4-5ft from the SSW with very long 17-18 second periods. The energy hits 2637 (moderate-strong). This is a session for the fit and the keen; the offshore wind will hold up the faces, but you'll work for every wave.

Wednesday the 16th is a big day. 10ft of S swell with a 15-16 second period. That's solid. The wind stays fresh offshore from the ESE at 22-25 mph, so it's clean and powerful. Energy is a massive 5693 (very strong). This is expert territory. The swell is big, the period is long, and it's going to unload on the reef. If you've got the experience, this is the standout of the first week.

Thursday the 17th is still good, with 7ft S swell, offshore ESE wind at 19 mph, and energy around 1430-1811 (moderate-strong). Clean and punchy. The swell drops through Friday the 18th to 4ft, but the offshore wind holds, making for clean, fun waves.

Saturday the 19th through Monday the 21st of September, the swell drops further to 3-3ft. The wind is lighter—ESE at 6-12 mph, offshore. By Monday afternoon, the period jumps back to 18 seconds with a 3ft SSW swell, and the energy reading of 1118, giving you clean, long-period runners that will be fun on the reef.

The real magic looks to be kicking off around Tuesday the 22nd through Thursday the 24th of September. On the 22nd and 23rd, we've got 4-6ft SSW swell with light offshore winds (6 mph from ESE) or even glassy conditions. The energy is solid (774-1787). But Thursday the 24th morning is dead glassy—SE wind at just 3 mph. You'll have 4ft of SSW swell with a 14-second period and an energy of 1066. That is a session to circle on the calendar. The afternoon brings a longer 21-second period swell at 5ft with a cross-off wind, still clean.

Friday the 25th of September is another standout potential. 8ft SSW swell with a 17-second period, light cross-off winds, and energy at 3062 (strong). The faces will be clean and powerful. This is high on the list.

The weekend of the 26th and 27th gets a bit messy with rain showers and strong cross-off winds (22-25 mph), and the swell quality drops. The 27th still has clean 5ft swell with fresh offshore wind, but it's a step down.

Wrapping into Monday the 28th of September, you've got a return to clean conditions with 6ft SSW swell and a moderate offshore breeze. It's solid, but by then we're into the end of the window.

The two true standouts? The first is Wednesday the 16th of September for the big-wave crew after that 10ft, very-strong-energy SSW swell with clean offshore wind. The second, for a more manageable but superb session, is Thursday the 24th of September, with that 4ft SSW groundswell and glassy conditions in the morning. Get on it.

Rusty.
