Running inland from Lisboa through Ribatejo and the Beiras into Trás‑os‑Montes, this route feels more continental than the coastal options, with hotter, more exposed summers and a wetter, breezier finish up north. Many walkers target March, April, and May for cooler days, spring greenery, and longer light. Across the year, summer heat builds on exposed southern stretches, northern Portugal and Galicia remain changeable and wetter, autumn turns showery with lingering warmth in the south, and winter features frequent rain, cool mornings, and short daylight.
