The Lowdown
Right, let’s have a look at what’s on offer for Trevone Bay over the next couple of weeks. Straight up, I’ll be honest with you – it’s a pretty bleak stretch. We’ve got a long gap of nothing but tiny, weak waves with poor conditions for the first week. The water’s sitting at 66°F at the start, which is a touch warmer than normal for this time of year, but that’s about the only upside.
We don’t see anything worth dragging your board out for until Thursday the 14th of August. Even then, it’s not a classic. The morning of the 14th has a glassy surface with the wind from the NW at just 3 mph, which is a major positive for clean conditions. The swell is a tiny 3ft from the west, with a period of 8 seconds, and the combined energy is only 109 (moderate). It’s described as “surfable but very ordinary.” It’s a beginner-friendly wave, but it’s not going to get the heart racing.
After that, the outlook turns back to small, messy, and onshore junk. The period around the 17th to 20th of August sees a bit more energy, with swell heights reaching 4ft and combined energy up to 341 (moderate), but the wind is consistently onshore or cross-onshore, mainly from the NW and NNW at 12-19 mph, making it choppy and sloppy. The swell is coming from the west and WNW, which is the optimum direction for Trevone Bay, but the wind is ruining it. The period is short, mostly 6-10 seconds, so it’s weak wind swell, not proper groundswell. This setup looks more interesting for kites than paddle surfing, to be honest.
There’s a brief window on the morning of the 18th of August with a cross-offshore wind from the south at 12 mph and a 4ft west swell, giving clean conditions, but it’s still a short-period swell (8 seconds) and the energy is moderate (249). It’s a maybe, but you’d be scratching for a decent one.
So, the best of a bad bunch is that Thursday morning, the 14th of August. It’s the only time the stars align even a little bit. Expect a clean, glassy morning with small, weak waves. It’s not a standout for anyone but a beginner, but it’s the only surfable window in the whole 16 days. After that, it’s back to a long run of poor surf until the end of the period.

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.
