The Lowdown
Alright, grab a coffee, 'cause I gotta be straight with you – the surf outlook for Troia over the next 16 days is a tough one. There's no real run of quality waves on the cards. The forecast kicks off on Friday the 24th of July, but we're looking at a pretty grim stretch until we get to the very back end of the window.
The whole 16-day period is a write-off for decent surf. We're talking about a long, dry gap with no real recommendations. The forecast shows a few tiny pulses of swell, but they're all tiny and mostly junk. The combined wave energy is weak, often a single-digit or low two-digit number (27, 63, 9, 7, 13) – basically nothing worth paddling out for. The swell direction is mostly from the west-northwest, which is okay for the spot, but the size is pitiful, never getting above 5 ft, and the periods are short, around 4 to 6 seconds, meaning weak, crumbly waves.
The winds are a constant problem, too. Most afternoons are a cross-onshore or onshore mess, making it choppy. Mornings are often clean, but there's just no swell to go with them. If you're a true beginner and just want to get wet, you could look at the glassy morning of Tuesday the 28th of July, when it's dead calm (0 mph wind) and the swell is a tiny 1 ft from the WNW, but the period is a pathetic 4 seconds. The energy is a measly 7. It's not really surf. The same goes for the morning of Monday the 3rd of August, with a bit of glass and a 2 ft NW swell, but again, period is only 5 seconds and energy is 13. It's a flat, frustrating outlook.
The only glimmer, and I mean a tiny glimmer, comes right at the end of the forecast. On Thursday the 7th of August, there's a 0.3 ft swell from the W with a very long period of 13 seconds. That's a pulse of proper groundswell energy, but it's so small it's practically a ripple. The combined energy is still a pathetic 6. The wind is clean and off-shore from the NNW (16 mph), which is a bonus, but the wave size is just not there. For a spot like Troia that's already inconsistent, this is a long, blank run. It's not abnormal for the area, but it's still a bummer. Honestly, with no real swell and constant wind, if you're feeling desperate, the setup at Troia looks more interesting for a kite than a paddle this fortnight.

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.
