Trevone Bay Surf Forecast and Surf Report

Alright, let me break down what’s happening at Trevone Bay over the next couple of weeks, in feet and miles per hour for you.

Honestly, it’s a rough start. From Monday the 14th through Sunday the 20th, the surf is flat-out poor. Onshore and cross-shore winds, lumpy chop, and the scores are rock bottom. Swell hangs around 4ft to 7ft from the west and west-northwest, but the wind ruins every session. The combined wave energy is moderate that first week, peaking at 877 on Wednesday the 16th, but it’s messy. Not worth paddling out.

There’s a real dry spell – no decent surf until Monday the 21st, and even then it’s only marginal that morning. Swell drops to 3ft from the WNW with a 13-second period, light cross-shore wind. Not great, but at least it’s not total rubbish. Tuesday the 22nd morning has a bit more size at 5ft but short period – only 7 seconds – and cross-onshore wind.

Now, Wednesday the 23rd is the first little standout. Morning session looks glassy – wind is from the ESE at just 3 mph, and the water is flat calm. Swell is 4ft from the west at 10 seconds. Combined energy is 286, moderate. This is the first time you’ll find clean, rideable waves. The water temperature is about average for this time of year, nothing wild.

Thursday the 24th is small and clean in the morning with a cross-offshore breeze, but only 2ft. Friday the 25th is another good shout – morning brings 5ft from the WNW, 14-second period, and a clean offshore wind from the ESE at 16 mph. Combined energy hits 900 – moderate to strong – and this is the best looking swell-wind combo of the whole run. Afternoon stays good with 4ft and offshore winds.

Saturday the 26th has clean offshore winds but the swell drops right off to 3ft and 2ft – only for the small-wave crew.

Then Sunday the 27th… whoa. The swell is predicted at 12ft from the west, 11-second period, with light offshore wind from the SSE. Combined energy is a massive 2501 – very strong. But that’s way too big for Trevone Bay. This is expert-only territory and even then, it’s likely to be a washing machine. Beginners, stay well clear. The forecast says it’s too big for this break, and I agree.

Monday the 28th morning is glassy again with 4ft from the WSW, 8-second period, energy at 472. That’s a solid, clean option for a weekday session before the wind turns onshore later.

So overall, the best on offer? Friday 25th September – both morning and afternoon – with clean offshore wind, solid 5ft and 4ft swell from the WNW, and that long 14-second period groundswell. That’s the one to circle. Wednesday 23rd morning is the only other glassy, clean window with decent size.

Keep an eye on the long-range but don’t hold your breath for the big stuff – it’s too much for this spot.
