The Lowdown
Alright, Rusty here. Let's have a look at what's coming down the pipe for Reef la Maddalenetta.
To be straight with you, the next week and a half is a tough stretch. We're looking at a long run of flat, messy, or just plain poor surf from now right through to the morning of Thursday, August 27th. The water is sitting at 83°F, which is a good 5°F warmer than usual for this time of year, so it feels like a warm bath. The only thing moving on the surface for most of that time is a lot of cross-onshore junk from the NW, kicking up chop. There are a few moments of glassy conditions, like Monday morning the 17th or Wednesday morning the 19th, but there's simply no swell to go with them. It's a real bummer of a stretch.
Now, Thursday morning, August 27th, is the one and only standout in this whole 16-day window. It’s a proper flash in the pan. We’ve got a solid 8ft groundswell rolling in from the NW, with a period of 9 seconds. That's pushing the combined energy up to 1541 – a very strong pulse of energy. For a reef setup like this, that's a serious amount of water moving. The wind is glassy out of the SSE, which will keep the surface clean as a whistle. However, this is a wave for experienced surfers only. At 8ft, that's expert territory, especially on a reef. The only downside is that the afternoon sees the wind swing back onshore from the NW, so hit that morning session hard. The swell direction is coming from the NW, which is a great match for the optimum swell direction for this break.
After that peak, it drops off quickly into another stretch of weak, messy waves right through the end of the month.
So, to wrap it up: the whole first two weeks of this forecast are a write-off. The only moment worth paddling out is the morning of Thursday, August 27th, for the experienced crew. It’s going to be a heavy, clean, powerful session, but it’s a short-lived window before the chop returns.
Rusty.
