The Lowdown
Alright, Rusty here. Let’s take a look at Trevone Bay for the next couple weeks.
Honestly, it’s a grim outlook. Almost the whole 16 days is a bust. The water’s running at 66°F, which is a touch warmer than usual for late August, but that’s about the only bright spot.
We start Friday, 28 August, and it’s a no-go. Fresh cross-onshore wind from the WSW at 19 mph has the place lumpy with weak, short-period swell. Combined energy is only 70 – weak stuff. Saturday and Sunday have some cleaner spells, like Saturday morning with a 5ft SW swell and a clean cross-off wind, but the quality doesn’t add up to a recommendation. Sunday morning goes clean again with a 5ft WSW swell, but with combined energy at 366 (moderate), it’s nothing special.
Monday 31 August is the only real standout, but it’s not for everyone. Monday morning sees a 10ft swell from the W with a 9-second period, and a clean onshore wind from the WNW at 19 mph. That combined energy is pumping at 1374 – strong to very strong. Waves will have some serious power. But at nearly 10ft, this is expert territory only. Beginners, stay on the sand. The wind is onshore, so it’s not glassy, but for the big-wave crew, there’ll be some proper sets. Monday afternoon drops to 8ft, still clean, but still big.
After that, it’s a slow fade into waist-high slop with cross-onshore winds. By the 6th and 7th of September, we’re looking at knee-high dribble with energy in the 50–100 range. The 11th of September is a joke – a 0.7ft swell with a 21-second period that has nothing behind it.
Then Saturday 12 September shows a pulse back up to 6–7ft from the W, but the wind is howling strong cross-onshore at 25–28 mph. That’s kite-surfing weather, not paddle surfing.
So, the only real window for experienced surfers is Monday 31 August morning. For everyone else, this is a 16-day stretch of almost nothing worth paddling for. It’s a quiet time at Trevone Bay.
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.
