The Lowdown
Right then, let’s have a look at the 16-day window for Trevone Bay. To be straight with you, it’s going to be a tough watch for a while. The pattern is a long stretch of messy, onshore junk with barely any rideable energy. We’re talking about a proper gap of poor conditions that runs from now all the way through until the 28th of July. There’s just no quality on offer, mostly cross-on winds and choppy slop, with swell heights barely brushing 4 ft and combined energy sitting in the weak to moderate range (below 100). The swell periods are short, often 5 or 6 seconds, so you’re getting windswell, not proper groundswell.
The standout window, and really the only time to even think about a paddle, is the morning of Monday the 28th of July. The water temperature is a touch warmer than normal at 64°F, so that’s a nice bonus. For that morning, Trevone Bay picks up a 3 ft W swell with a period of 6 seconds. The combined energy is moderate at 120. The real key here is the wind: it’s a glassy, 3 mph Westerly. That’s about as clean as it gets. The setup is a beach break, so don’t expect long walls, but with those conditions, it’ll be surfable and the crowd factor is "sometimes", so you might have a few out, but a window like this is rare. The swell is small enough for beginners, but the lack of power means it’ll be a grovel session.
After that, the wind picks back up on the 29th with a 5 ft W swell and 19 mph winds, which is too big and messy for a decent go. The 30th and 31st stay in the same boat with cross-onshore winds and lumpy conditions. So, take that glassy morning on the 28th, and don’t blink.

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.
