Weather forecast builder for the Camino Portugués - Senda Litoral

This coastal path from Porto to Santiago follows long promenades, wooden boardwalks, and open beaches, offering steady sea breezes, far horizons, and quick‑changing Atlantic weather. May, June, and September align with longer days, moderate temperatures, broad service availability, and generally calmer winds than midsummer. Atlantic squalls remain possible year‑round; short rain bursts become more frequent in Galicia, wet boardwalks can be slick, and some beach variants depend on tide and swell.

• Spring: Alternating sunshine and showers define this period; greener landscapes, variable winds, and slick boardwalks, with Galicia seeing frequent short downpours.
• Summer: Longer days and predominantly sunny stretches meet steady northerly headwinds on exposed promenades; heat builds on paving and sand, with intermittent showers.
• Autumn: Mixed sun and rain with gradually earlier dusk; rainfall increases toward Galicia, and occasional heavier bursts advance through fronts later in the season.
• Winter: Frequent rain, strong coastal winds, and short daylight dominate; moody seascapes alternate with brief sunny spells, and some small‑resort services reduce mid‑week.
