Alright folks, Rusty here. I'm looking at the Troia charts and I've got some news you probably don't want to hear.
We’re looking at a real tough period. From the 10th right through the 16th of July, that's nearly a week, there is absolutely nothing to get excited about. It’s flat or so small it’s not worth the walk. The wave energy numbers are low, single digits mostly, so you'd be waiting all day on a board for a ripple. Big ol' gap in the action.
We finally get a pulse of swell showing up around Friday, the 17th of July. It’s a NW swell with the biggest energy of the whole outlook, hitting a moderate 102. The wind will be blowing cross-offshore from the NNW at about 15-20 mph, which will keep the face pretty clean. You’re looking at wave heights around 5 ft from the NW. But the period is a short 5 seconds, so it's a jumbled, wind-driven wave, not the kind that will reel off down the beach.
Saturday the 18th of July has even more energy, up to 156, and the swell is a bit bigger, about 5 ft from the NW. Sounds good, right? Wrong. The wind cranks onshore from the NW at 20 mph, making it lumpy and messy. With that short period and the wind chop, this setup honestly looks more like a kiter's day than a surfer's day at a spot like this.
After that brief moment of life, it flatlines again. From the 19th to the 25th, we’re back to those tiny, weak swells that just don't have any push. The water is a very unusual 75°F, much warmer than normal for this time of year, but that’s about the only highlight.
If you’ve got to paddle, the early session on Friday, July 17th, is your only real option, and even that's a stretch. Otherwise, this is a blank spell for the area. It happens. We'll see if the next set of charts brings any better news.

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.
Troia is 9 km (6 miles) from Setubal. If you plan a holiday in Portugal - Alentejo, look for hotels and other accommodation in Setubal. Setubal has rooms for a wide range of budgets as well as car hire and transport links.
