The Lowdown
Alright folks, Rusty here. Let's talk about what we've got lined up for Trevone Bay. I'll be straight with you – the next week and a half is going to test your patience. There's a long, dry spell of poor conditions ahead.
Looking at the whole run, we have a big gap of almost no worthwhile surf from right now all the way until the 23rd of August. For most of that time, it's either too small, the wind is onshore or cross-onshore which is making things lumpy or choppy, or the periods are just too short to hold anything decent. You’d be spending more time sitting on your board than riding waves.
The only real glimmer of hope, and it’s a bit of a long shot, shows up on the morning of Sunday the 23rd of August. That's the one to keep an eye on. We're looking at a 7ft swell from the west, with a light southerly breeze providing a clean, cross-offshore wind. The wave energy jumps right up to strong levels (600) which is the biggest reading in the whole period. That kind of setup should make for some clean, lined-up waves at the Bay. But this is far out, so treat it as a promising possibility, not a guarantee. The afternoon on the 23rd looks like the wind really picks up, so the morning is your window.
Before that, there's just nothing to get excited about. We've got some days with a bit of size, like Tuesday the 18th with a 5ft swell, but the wind is messy and onshore, making it a chop fest. You might see a small, clean window on the morning of Tuesday the 25th, with a tiny 2ft west swell and glassy conditions, but it's a very small, weak wave. For beginners who just want to bob around, that could be safe, but for anyone wanting a real ride, it's not worth dragging the board out for.
So to sum it up: it’s a tough outlook. The water at Trevone is currently much warmer than normal for this time of year at 67°, but that won't make up for the lack of quality. Keep an eye on the 23rd of August for the best shot at a proper session.
Stay patient,
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.
