The Lowdown
Alright, let’s get this out there. The next couple of weeks are looking pretty flat and uninspiring for the most part. We’ve got a long stretch of small, messy, and wind-affected waves ahead, so you’ll need to be patient. The water is running a touch warmer than usual for this time of year, which is a bit of a bonus for the summer sessions.
The first real glimmer of anything surfable shows up on Wednesday morning, August 12th. It’s not going to be pretty, but there’s a pulse of west swell starting to fill in. The morning is looking at a modest 3ft with a light cross-shore breeze, but by the afternoon the wind is set to go glassy. That’s the call. It’s a small, clean window with maybe 3ft of west swell wrapping in. The energy is still pretty weak (142), but it’s the cleanest we’ll see for a while. Trevone Bay is the spot, and it’s a beginner-friendly wave, so it could be fun for a splash around on a longboard.
After that, the wind gets messy again. Thursday the 13th brings in a bit more size, up to 4ft, but it’s chopped up by a moderate cross-onshore breeze, so it’s going to be a bit of a battle. The energy is ramping up (277), but it’s not going to be clean. The rest of that week is a write-off, with a lot of onshore wind and lumpy conditions.
We’ve got a bit of a lull over the weekend, with the swell dropping back down. The wind stays up, so it’s mostly going to be small and bumpy. Not worth getting too excited about.
There’s another slight bump in the swell around the 22nd, but the wind is all over the place. The morning of the 22nd is small, but the afternoon sees a bit more size (4ft) with a short period (6 seconds) and a cross-onshore breeze. It’s going to be a bit bumpy and weak.
The real standout, and it’s a long way off, is Monday, August 24th. We’re looking at the biggest swell of the whole period, with 5ft of west swell expected in the morning. The energy is solid (432), and the wind is only light cross-shore. This is the one to keep an eye on. It’s a while away, so don’t book the time off just yet, but this has the potential to be the best session of the fortnight. The afternoon drops slightly to 5ft, but the wind swings onshore, so the morning is the window.
All in all, Wednesday the 12th for a clean, small wave, and then keep your fingers crossed for Monday the 24th for some proper size. The rest is mostly a waiting game.

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.
