The Lowdown
Hey, Rusty here, checkin’ in from Rade de Croisic. We’ve got a long sixteen-day window ahead, so let’s get into it.
Right now, from Tuesday the 15th through Thursday the 17th, it’s flat and ugly. Swell between 1ft and 4ft, mostly cross-onshore winds, and wave energy is low to moderate at best—25 to 228. Choppy, lumpy, not worth wetting a suit.
Friday the 18th morning brings a pulse: 4ft west swell at a very long 17 seconds, with energy at 1306 (strong). But the wind is cross-on from the NW at 12 mph, and it’s only a marginal forecast. Big groundswell but messy. For experts only if you’re feeling it.
Saturday 19th and Sunday 20th are small again—3ft to 3ft—with onshore or cross-on winds. Sunday morning goes glassy from the SW with 2ft swell. Clean but tiny. A 1 out of 10 on quality.
Monday 21st through Thursday 24th stays small (1ft to 2ft), but the wind turns offshore or cross-off from the ENE at 9 to 15 mph. Wednesday the 23rd morning is the best of this stretch: 2ft west swell at 14 seconds, clean with moderate offshore wind, and a score of 2. Fun little longboard waves.
Friday the 25th is still small and offshore—1ft—but Saturday the 26th morning jumps to 4ft from the WSW at 17 seconds, with fresh offshore ENE wind at 18 mph. Energy at 852 (strong). The afternoon is the real standout: 5ft from the WSW, 15-second period, lighter cross-off at 9 mph, and a score of 3 with the note “expect very good surf conditions.” This is the best in the outlook—clean, punchy groundswell. For experienced surfers only at this size.
Sunday the 27th keeps it going with 3ft to 3ft west and WSW swell, offshore from the E at 12 mph, clean. Good fun.
After that, Monday 28th to Wednesday 30th fades to 1.0ft to 2ft with onshore or glassy winds, and energy drops to weak (22 to 84). Not much left.
Bottom line: Saturday the 26th afternoon is your day—biggest, cleanest swell of the period. Water temp is 68°F, which is a touch warmer than average, so a springsuit will do. Crowds can show up sometimes, so get out early.
Rusty.
