The Lowdown

Alright folks, Rusty here. Gotta be straight with you—this is a tough stretch for waves around here. We’re looking at Reef la Maddalenetta for the whole 16-day window, and honestly, it’s a quiet period with a couple of late-game promises.

The first week and a half is a real struggle. We kick off with tiny, weak energy readings, mostly below 25 (combined energy of all swells directed here) and often less. You’ll see glassy mornings on the 4th, 7th, and 9th with the wind a gentle easterly, but with swell heights barely scraping 2ft from the WNW and a short, weak period around 4-6 seconds, there’s nothing to ride. The water’s a notable one though – sitting at 82°, which is a solid 6° warmer than average for this time of year. That’s unusual, keeps the shorts on, but doesn’t help the surf. This flat spell drags through to the middle of the second week.

Then, on the 10th of September (Thursday morning), we get a pulse. Swell bumps up to 7ft from the WNW with a moderate 9-second period, and the energy kicks into moderate territory (615). The wind is a light cross-shore, so it’s clean-ish. But the score is marginal – that size is starting to get too big for beginners, and with a spot that *rarely breaks*, catching it right is a gamble.

The real standout, though, is the 16th of September (Wednesday). A proper groundswell arrives: 10ft on the Wednesday morning, building to 12ft in the afternoon, both from the NW with a 10-second period. The energy readings are huge – 1883 and 3879 – showing strong to very strong wave energy. The morning has a fresh offshore breeze from the NE, keeping it clean. This is expert territory – over 8ft, so only for the skilled crew. For a reef break that rarely works, this is a special, dangerous opportunity. After that, it drops back down through the 17th and 18th with cleaner but smaller 5ft to 2ft waves.

Bottom line: The first 11 days are a write-off. The only two days that matter are the 10th for a bigger, cleaner session for intermediates, and the standout is the 16th – a big, clean groundswell for experts only. Keep an eye on that one, but the long range means there’s some uncertainty.

Rusty.
