The Lowdown

Alright, this is Rusty. Let's have a look at what's coming up for Trevone Bay.

Overall, it's a pretty grim stretch for the next two weeks. The pattern is a long run of poor conditions, with very few windows that are even worth paddling out for. We're looking at a lot of cross-onshore winds, lumpy and choppy seas, and a general lack of quality. There's a gap of about four days of truly poor surf before we see anything that's just "surfable."

Let's start with Thursday the 20th of August. There's a pulse of swell coming in, with waves around 8 ft from the WNW, and combined wave energy hitting 799 (moderate to strong). The problem is it's raining and the wind is a fresh onshore breeze, so it's going to be a messy, blown-out mess. Not one for the log.

Friday the 21st of August is the first real glimmer of hope. The morning is looking like the only decent option in the first week. We've got a light breeze from the ENE, which is cross-offshore, and the surf is a clean 3 ft from the W. The swell period is a short 8 seconds, so it'll be a bit weak, but it’s the cleanest it will be. Expect crowds at this spot, especially when it's the only clean wave in town.

The next real chance comes on Tuesday the 25th of August. The morning is clean again with a light S cross-offshore wind and 3 ft from the WNW (period 10s). The afternoon picks up a little, with 4 ft from the W and a light S breeze still holding it clean. The combined energy is moderate (144 and 233). This is probably the best-looking combo of the whole window: clean, light winds, and a little more period.

After that, it's back to a mess of onshore winds and poor conditions through the end of August and into September. There's a bit of a swell pulse on the 29th of August with 6 ft waves and strong energy (550), but it's blown out by fresh onshore winds. The water temp is about 66°F, which is much warmer than normal for this time of year, so at least it won't be cold while you're getting blown off your board.

Looking into the second week, the 1st of September brings a 6 ft swell from the W with a clean cross-offshore breeze in the morning. The combined energy is 449. It's a promising shape but it's a long-range call, so don't hold your breath. The 2nd of September is similar, with a clean 5 ft option in the morning.

Honestly, if you're a kiter, the strong onshore days like the 20th and 29th of August might be more interesting than a paddle. For the rest of us, it's a waiting game.

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.
