The Lowdown
Alright folks, Rusty here, checking in for the Trevone Bay stretch. Gonna be honest with you, it’s been a rough stretch and the surf has been flat-out poor for a while. The first recommendation we see is a proper wait. We’ve got a big gap of no-good surf from now all the way through the beginning of September. You’re looking at a solid week-plus of lumpy, blown-out, or just plain tiny junk. Hang tight.
Alright, things start to look like they might be turning a corner around Monday, September 7th. The morning brings a light offshore breeze from the ESE at just 3 mph, which is a big deal for cleanliness. The swell is a clean 6 ft from the west with a solid 11-second period (groundswell). The combined swell energy is solid at 889, and conditions are looking clean. This is the first real standout in the whole forecast.
Then we get another big moment on Thursday, September 10th. The morning is looking primo with an offshore breeze from the southeast at 12 mph. Swell pushes up to 8 ft from the WSW with a short-ish 8-second period, but the energy is solid (782) and the wind is cleaning it up nicely. Conditions are looking very good indeed.
But the real gem, the one to circle on the calendar, is Friday, September 11th. Morning session looks incredible. We’re talking an offshore cross-off breeze from the south at just 6 mph. Swell sits at 7 ft from the west with a very long 14-second period (groundswell). The combined energy is pumping at 1744. That’s excellent surf, but it’s a big one over 7 ft, so this is for experienced surfers only. It’s going to be clean, powerful, and with those long gaps between sets, paddling out won’t be a total war. This is your best bet by far.
Later that afternoon, still good, with a 7 ft west swell and a 12-second period, still with clean winds.
Beyond that, the week of the 12th settles back down into more average, smaller conditions. The 13th of September Sunday morning shows a clean 6 ft from the west with a 9-second period and light winds, which is a solid way to wrap things up if you missed the big Friday.
Water temp is sitting about 66°F, which is a touch warmer than normal for this time of year. You’ll feel it.
So to sum it up: suffer through the dry spell. The 7th is a glimmer, the 10th is looking good, and Friday the 11th of September is the big call. Mark it.
Rusty.

Information about the Trevone Bay Surf forecast
The above surf forecast table for Trevone Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Trevone Bay can be found by selecting the local surf guide option on the grey menu. Our Trevone Bay surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Trevone Bay) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Trevone Bay may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
