Camino Portugués
Weather in January

Weather Overview

January on the Camino Portugués presents mild but chilly conditions typical of northern Portugal and Galicia in winter. Daytime temperatures generally fall between 11°C and 16°C, though this varies noticeably along the route. The section through Porto and Braga near the start offers slightly warmer days around 14–16°C, while Galicia in the final stages becomes progressively cooler, averaging 12.6°C. Nights are consistently cold, ranging from 3°C to 11°C depending on elevation and location, so expect frost on ground and vegetation most mornings.

Rainfall is the defining challenge of January walking here. The route receives frequent precipitation, with seven consecutive rainy days forecast for the Galician section alone. Viana do Castelo and Galicia account for most of the 108mm monthly total, and showers tend to be regular rather than torrential. Wind gusts can reach 56 km/h on exposed ridgelines and open coastal sections, particularly between Porto and Viana do Castelo, creating wind-chill that makes conditions feel considerably colder than the thermometer suggests.

Elevation gains are modest overall, but the modest hills still create cooler, wetter conditions at their summits. Nights at higher points drop sharply and exposure increases wind impact. Walkers should prioritize layering systems: start days in full waterproof kit and begin walking early to maximize daylight, as January darkness arrives by 5 p.m. Wet gear dries poorly in winter, so frequent changes and good rain protection are essential, not optional.
