The Lowdown
Alright, this is Rusty. Let's be real honest about Troia. The outlook for the next 16 days is pretty bleak for paddle surfing. The data shows a whole lot of flat, small, and messy conditions. We're looking at a long stretch of nothing, really. For the first week, from July 25th right through to about August 4th, there's no real surf to speak of. The swell energy is consistently weak, with values mostly in the single digits or low double digits, peaking at a paltry 80 (moderate energy) on the 25th afternoon, but that's a 4.3ft windswell from the WNW with a short, weak period of 5 seconds. That's just a lumpy, wind-blown mess. You'll see a few glassy mornings with zero swell, which is great for a swim, but not for a wave.
The only glimmer of something that resembles a wave comes on the afternoon of Tuesday, August 4th, with a 3ft NW swell and a slightly better 6-second period. The combined energy is 57 (weak), and the wind is a cross-shore from the NW at 12 mph, which will create a bit of a cross-chop. It's not pretty, but it's the best we've got. For a beginner spot that's already inconsistent, this is a tough run. If you're a kiter, however, the afternoons with a cross-onshore wind and a bit of chop might look more interesting than anything for a surfboard.
The second week, from August 5th onward, is just as quiet. The odd ripple of 0.3ft from the south with a long 12-14 second period pops up, but with such tiny size, it's next to nothing. The water temp is about average for the time of year. Honestly, this is a blank run that's pretty normal for the area when it's this flat. Sometimes forecasts change, but right now, leave the boards at home and grab a fishing rod.

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.
