Camino Portugués
Weather in March

Weather Overview

March along the Camino Portugués brings mild daytime temperatures ranging from 13 to 16 degrees Celsius, though nights can dip to around 5 or 6 degrees, particularly at higher elevations. The route grows slightly warmer as you move north from Porto, where daytime averages hover near 14 degrees, into the Braga and Viana do Castelo regions where temperatures reach around 15 degrees before cooling again in Galicia. This modest warming inland reflects the transition away from coastal influence, though the overall character remains cool rather than cold.

Rainfall is a defining feature of March on this route, especially in Galicia where rain falls on seven out of seven days, accumulating to roughly 95 millimetres across those seven stages alone. Northern Portugal experiences lighter precipitation, with Porto and Viana do Castelo seeing rain on about half the days but in minimal amounts. Wind gusts can reach 71 kilometres per hour on exposed sections, making coastal stretches and ridgelines particularly gusty and uncomfortable underfoot.

The modest elevation gain—353 metres total ascent across twelve stages—means no true mountain passes, yet cooler nights remain noticeable at higher points. Pack waterproof layers that compress well, and consider starting walks earlier in the day to avoid afternoon rain and wind. Multiple thin layers work better than heavy insulation, allowing you to adjust as temperatures fluctuate between morning chill and midday mildness.
