The Lowdown
Alright, Rusty here, and I’ve been studying the maps for our local stretch. It’s a slow start, but there’s a couple of good days to circle on the calendar.
The first few days are a bust. Saturday the 29th and Sunday the 30th are small and choppy with short-period windswell. Not worth the wax. On Sunday afternoon the wind goes glassy, but the swell is only 3ft, so it’s barely a paddle. We’re waiting for the first real juice.
That arrives on Wednesday the 2nd of September. The combined energy jumps to a strong 1105, with a clean 8ft swell out of the south. Light offshore winds in the morning will make for some serious shape. This one is for the experienced crew, as it’s too big for beginners. The water is about average for the time of year at 68°.
After a few more average days with onshore slop, the real highlight shows up. Monday the 7th of September morning brings another big spike in energy to 1044, with a 7ft south swell and a 10-second period. Offshore winds from the WSW will keep it glassy. Another expert-level session due to the size.
Then, a sleeper pick: Thursday the 10th of September. The swell drops to 5ft – 5ft from the east, but the wind goes glassy all day. That means super clean, user-friendly waves. The energy is moderate at 334-399, but the quality of the conditions will be the star.
Looking a bit further, Saturday the 12th of September morning shows a promising 5ft east swell with a longer 10-second period and offshore wind, generating 776 of combined energy. It’s a long-range call, so it’s not locked in, but worth keeping an eye on.
The break in the mix is Atalaia (Molhes) . It’s fairly consistent, but not always firing. For the two big standouts (Wednesday the 2nd and Monday the 7th), the south swell will hit this beach/jetty setup hard, and the offshore wind will clean it up. There’s a few quiet 2-3 day gaps in between, so pick your moments. That Thursday the 10th with the glassy conditions will be the best for a relaxed, fun session.
Rusty.
