Trevone Bay Surf Forecast and Surf Report

Alright, Rusty here. Let’s break down what Trevone Bay is looking like for the next couple of weeks. I’ll be honest, it’s a pretty bleak outlook for most of it, with a lot of lumpy, choppy, and just plain ordinary conditions. The water is sitting at 65°F, which is much warmer than usual for this time of year, so at least you won’t be cold waiting for a wave that’s not coming.

The first real chance to paddle out is Wednesday morning, the 9th of September. We’ve got a 3ft WNW swell, with a period of 9 seconds, and a moderate combined energy of 219. The wind is light offshore from the NW, so it’ll be clean. The problem is, the surf quality is poor, and it’s just a weak, small swell. It’s rideable for a beginner, but that’s about it.

From there, it’s a rough ride. Thursday and Friday see a mix of cross-shore and onshore winds, with the swell hitting 7ft on Thursday afternoon but with a short 8-second period and a fresh cross-shore wind creating a lumpy cross-chop. The combined energy spikes to 482, but it’s not a friendly energy. We then go through a long stretch from the 10th right through to the 22nd of September where the outlook is dead. Every session is tagged as “poor surf conditions” or “marginal,” with cross-onshore winds, choppy faces, and very ordinary conditions.

There is a slight glimmer on the morning of Tuesday the 15th of September. A 4ft W swell, 8-second period, combined energy of 180, and a light cross-offshore wind from the south makes for a clean surface. The file says “surfable waves but very ordinary conditions.” It’s small and weak, but if you’re desperate, you could get a few waist-high ones.

Now, the real standout, but a long way off, is the morning of Sunday the 20th of September. We’re looking at a solid 10ft WNW swell, but the combined energy is a massive 1106. The wind is light and cross-on from the WNW, so it’s not going to be glassy. The file actually says the swell is predicted to be too big for this break. This is expert-only territory, and even then, it’s going to be a washing machine. The period is short at 8 seconds, so it’s not a clean groundswell. This setup looks more interesting for a kite surfer than a paddle surfer.

Towards the end of the run, on the 23rd and 24th of September, we finally get a proper offshore wind. On the morning of Wednesday the 23rd, a clean ESE offshore breeze of 12 mph hits a 3ft W swell. The combined energy is a weak 88, and the period is 8 seconds. It’s surfable but very ordinary. The morning of the 24th is a bit better: a 3ft W swell, 11-second period, and a clean 12 mph offshore wind. The combined energy is 263. The longer period means better shaped waves, but it’s still small. This is the best of a bad bunch, but it’s a long week and a half away.

So, to sum it up: the first week is a write-off. The best on offer is the morning of the 24th of September, with clean offshore winds and a touch of long-period groundswell, but it’s tiny. The 20th of September is big, but it’s too big and messy for Trevone. Don’t get your hopes up.

Rusty, signing off.
