Troia - surf spot statistics

Best Surf Season (October - March)

The North Atlantic winter machine fires on all cylinders from October through March, delivering consistent, powerful groundswell to Troia's southwest-facing beaches. Average swell heights peak at 1.9-2.0 m in December and January, with long period waves averaging 12-13 seconds. The combination of strong extratropical lows spinning up in the North Atlantic and a favorable high-pressure ridge often sets up offshore easterly to northeasterly winds, keeping the surf clean and lined up. This is prime time for Troia, when the swell direction aligns from the SSW to W and winds blow from the N to E quadrant, creating perfect offshore conditions. Expect pumping, firing waves in the 1.5-2.5 m range on the best days, with the occasional XL pulse exceeding 2.5 m.

Fair Surf Season (April & September)

April and September are transitional months, offering a mix of fading winter energy and the first hints of autumn activity. Swell heights average around 1.5 m, with periods dropping to 11 seconds. While the Atlantic still sends consistent swell, the wind patterns become less reliable. The percentage of ideal offshore wind ranges from 32-35%, as the trade wind pattern starts to establish. Still, when a solid southwest swell meets a morning easterly breeze, Troia can dish out fun rippable waves in the chest-to-head-high range. These months are a gamble but can reward the patient surfer with uncrowded sessions.

Low Surf Season (May - August)

Summer brings a dramatic drop in both swell size and wind quality. From May through August, average swell heights hover around 1.0-1.2 m with periods sinking to 9-10 seconds, resulting in mostly small, weak, groveling waves. The dominant swell direction shifts to NW, which is not ideal for Troia's SW exposure, and the wind regime becomes dominated by strong northerly and northwesterly winds - onshore or side-onshore for this spot. The ideal offshore wind percentage plummets to 27-31%, leaving only the rare day when a light easterly breeze coincides with a small pulse of southwesterly swell. Overall, summer is a time for longboard or foamies, or just waiting for the autumn return.

May: Summer's Quiet Prelude

May sees the surf community shift into standby mode, with average swell height down to 1.2 m and period to 10.0 s. Ideal wind only hits 29%, with N (15.0%) and NNW (21.5%) becoming the dominant wind directions - but these are offshore for Troia? Actually NNW is onshore (blows from NNW, which is from the north-northwest, hitting the coast at an angle; given the coast faces SW, NNW wind is cross-shore to offshore? Let's analyze: For a SW-facing beach, wind from N is offshore (blowing from land to sea). NNW is slightly north of west? Actually NNW is north-northwest (337.5 degrees), which is offshore? No, wind from NNW blows towards the south-southeast, which for a SW-facing beach (orientation ~225 degrees) would be offshore? The coast of Troia faces SW, so the land is to the NE. Wind from N is alongshore from the north, but can be considered offshore? The given optimal wind directions are NNO, NO, ONO, O (i.e., NNE, NE, ENE, E). So N is not explicitly listed, but it's close. However, the data states wind is ideal 29% of the time, which should align with those directions. So N is likely favorable. But NW, WNW, W are onshore. So in May, NW and NNW winds are high but onshore. Swell is dominated by NW (40.2%) and WNW (32.8%), with W (13.6%) - mostly poor angles. Expect small, weak waves with onshore chop. Only when a southwesterly pulse (0.4%) meets a morning easterly does it get rideable. May is for longboard cruise or exploring other spots.
