Which trail suits your trip? Pick a month for typical weather, or your own dates for the forecast, rated at each trail's lowest and highest point. The best match comes first; the table below has the details. For winter trips, start with hiking in Europe in winter.
From typical weather: the 1991–2020 averages at the trail's lowest and highest point, corrected for height. A published season (a park that closes, huts that open) overrides the weather. A rating is a planning aid for the area, not a report of the trail: check the official warnings before you go.
Outside the published season. No walking season or closure is published by Sport Ireland or the official site. The long stages need long days: in December there are under 8 hours of daylight, less than the 30 to 34 km stages take. Check the forecast: the high passes, river crossings and lakesides are exposed in weather alerts, and the off-road sections are often wet and muddy.

Ratings are planning aids from typical weather or the forecast, not statements about trail conditions. Typical weather: TerraClimate 1991–2020 at each trail's lowest and highest point, corrected for height, with the Pico do Areeiro station on the Madeira peaks. Stays and status come from each guide's dated records.
