The Lowdown
Alright folks, Rusty here. Let's get into it. We've got a solid, long period, West swell on the way for The Gallows, but it's a tricky one. This spot is a powerful, advanced reef break that’s fairly consistent. The water temp is sitting at 65°, which is about a couple of degrees warmer than usual for this time of year, so it's a touch balmy.
That first week or so is a real mixed bag. The swell is pumping, but the wind is the enemy. Saturday the 5th is a write-off, with a NW wind blowing 19 mph straight across the face, making it a lumpy, choppy mess. Sunday the 6th through Wednesday the 9th sees a massive 12 ft to 13 ft SW swell rolling in, with a very long period of 16 seconds. The wave energy is huge, hitting 8296k on Tuesday, but the forecast is clear that the swell is predicted to be too big for this break. This is strictly for the experts only, and even then, it's a beast. The wind improves to a clean cross-off, so the faces will be clean, but 13 ft of SW groundswell is a serious, heavy commitment.
The real standout, and the only time I'd give a high recommendation, lands on the Thursday afternoon of the 17th of September. The swell drops to 12 ft from the WSW, still a meaty wave, but the period is a fantastic 15 seconds. The real magic is the wind: it's forecast to be glassy. Complete calm. For a reef break that handles a long period swell perfectly, this is a potential session of a lifetime. The wave energy is still very strong at 4640k, but that glassy surface will make it as clean as it gets. This is the best on offer.
The run from the 10th to the 12th of September is a real letdown. The swell drops to 4 ft with a weird 20-second period, and the wind goes straight onshore, making it a 2/10 at best. A complete waste of a good swell direction.
Then from the 14th of September onwards, the swell is back up to 10 ft to 13 ft, and the forecast is constantly saying it's too big. The winds are good but the size is just gnarly. The second week really just has that one golden window on the 17th. The 19th and 20th see more giant 16 ft+ swell, which is just a monster.
So, the bottom line: this is a two-week window of big, powerful, and often dangerous surf. The only true standout is that Thursday afternoon the 17th when it all comes together. Don't get caught out by the size the rest of the time.
Rusty.
