The Lowdown

Alright folks, Rusty here. Let’s talk about what’s cooking at Trevone Bay over the next couple of weeks.

To be straight with you, the pickings are slim for a good chunk of this forecast. The water is a touch warmer than normal for this time of year, sitting at 65°F, but that’s about the only thing that’s easy. For the first ten days, we’re looking at a long stretch of poor surf conditions. The wind is mostly onshore or cross-onshore, and the swell is all short-period windswell, under 8 seconds, making for a lumpy, choppy mess. You’ll see a bump in energy on the 5th of August, with combined energy hitting 383 (moderate), and waves around 6ft, but the wind is a fresh 19 mph cross-onshore, so it’s not going to be any fun – more of a kite session than a surf.

Things get a little cleaner on the morning of the 15th of August. The wind swings light cross-offshore from the SSE, and the waves are a clean 4ft from the WNW. The combined energy is only 101 (weak), so it’s not powerful, but the conditions are described as "clean". That’s your best bet for a surfable wave, though it’s still very ordinary.

The real stand-out, if you’re an expert and don’t mind a bit of waiting, is the morning of the 19th of August. The swell is a solid 10ft from the WNW, with a period of 9 seconds, and the combined energy is a massive 1480 (very strong energy). The wind is light offshore, nearly glassy. The catch? The forecast says the swell is predicted to be too big for this break. This is one for the very experienced crew only, and even then, it’s a promise that’s a long way off, so keep an eye on it.

So, to sum up: a long, quiet period of poor surf, then a small, clean window on the 15th, and a potentially massive, dangerous swell on the 19th. That’s the story.

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.
