The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the next couple of weeks around Troia are looking like a write-off for any decent surf. We’re staring down a long, flat spell with no real swell to speak of. The forecast shows a whole lot of nothing, with wave energy barely registering at all, so don’t bother checking the cams just yet.
We kick off on Thursday the 13th and it’s dead flat. The water temp is about what you’d expect for this time of year, so if you’re just going for a swim, it’s fine, but for surfing? Forget it. This flatness drags on through the weekend and into the next week. The only tiny blip is a little pulse of weak energy (34 mm) on Sunday the 23rd, but that’s a windswell with a period of just 5 seconds – that’s all chop and no push, and the wind is cross-onshore messing it up. That’s not surf, that’s a washing machine.
The whole 16-day window is a bust. There are no standout days, no hidden gems. Troia is an inconsistent spot at the best of times, and this is one of those stretches where you’re better off finding something else to do. The wind will be light and glassy on a few mornings, like the 16th and 17th, but with nothing to ride, it’s just a pretty morning. We’ve got nothing over 0.7 ft of swell for the entire period, so even the most optimistic surfer would be hard-pressed to find a wave.
Honestly, this is one of those rare blank runs where the ocean just shuts off. Don’t hold your breath – forecasts can change, but right now, it’s a paddling pool. Keep the board in the bag.
Rusty.

Information about the Troia Surf forecast
The above surf forecast table for Troia provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Troia can be found by selecting the local surf guide option on the grey menu. Our Troia 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 (Troia) 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 Troia 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.
