Trevone Bay Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what Trevone Bay has on offer over the next couple of weeks. I gotta be straight with you – it’s a bit of a tough stretch to start. The whole first week is a write-off with nothing but poor surf conditions and winds all over the shop. You’re looking at a gap of about 11 days before things start to get interesting.

The water’s sitting at 64°, which is a touch warmer than normal for this time of year, so that’s a small consolation if you’re just dipping a toe in.

From Friday the 22nd, we start to see a glimmer. Tuesday morning looks marginal, with a 4ft swell from the west at a 10-second period. The combined energy is weak – only 312 – and the wind is a gentle cross-shore. It’s not great, but it’s not terrible either. Then Tuesday afternoon picks up a bit with a 4ft west-northwest swell, a very long 12-second period, and a slight breeze. This is a groundswell, and while the energy is still moderate (418), the long period can make it a bit too lined up for a beach break like this. Still, it’s something.

Then we hit the real standout. On Wednesday the 23rd, we get a solid offshore breeze from the southeast, and that’s a major positive. The swell drops a bit – 2ft in the morning and 2ft in the afternoon, both from the west with periods around 9-10 seconds. The energy is very weak (91 and 63), but with clean, moderate offshore wind, these become those sneaky, fun little waves for a longboard or a fish. It’s not going to blow your mind, but it’s the first clean surf of the outlook.

Now, hold on to your board. The best of the whole run looks to be Thursday the 24th and Friday the 25th. Thursday morning brings a solid 6ft swell from the west at 9 seconds, and crucially, a moderate offshore wind from the south-southeast. The combined energy jumps to a strong 1055 – this is the real deal. The forecast says “very good surf conditions,” and I’d agree. For a beginner, that 6ft swell is getting a bit big, but if you’re competent, this is your session.

Friday morning the 25th keeps the momentum with a 6ft swell from the west-northwest at a long 12-second period. The wind is a gentle cross-offshore from the south, and the energy is 905 – strong but not as punchy as Thursday. Still, clean conditions with a long-period groundswell at Trevone? That could be magic. Be aware that the long period might make it a bit straight for a beach break, but with that wind, it’s worth a look.

After that, things fade. Saturday the 26th is back to poor conditions with a weak 3ft swell and a cross-shore wind.

So, to boil it down: the first 11 days are a no-go. The standout is Thursday the 24th of September, with the morning offering the best combo of size, offshore wind, and strong energy. Friday morning the 25th is a close second, cleaner but with a slightly less punchy swell. If you want clean but small waves for a log, Wednesday the 23rd is your quiet achiever.

Stay frothy,
Rusty
