Historical climate at one selected model cell. Higher routes, sheltered valleys and exposed ridges can differ substantially.
Model elevation: 149 m · Historical period: 1991–2025
Trail wind is not available here. This model does not resolve exposed ridges or gusts; check a local mountain forecast.
Selected cell: 53.5, -9.7
Temperature sampling window (local time, limited to daylight): 08:00–18:00.
A wet day has at least 1 mm of total precipitation (including snow water equivalent). It may rain for only part of the day.
A snow day meets either model threshold: 10% snow cover or 2 cm snow depth.
Choose a specific route and check its distance, ascent, difficulty, current access and forecast. These are not supplied by the climate model.
The monthly value represents the selected representative ERA5-Land grid cell. It deliberately does not pretend to describe every route across the region.

The record for these months is complete. They carry no hiking score because at least one critical component is at or below 20, and we would rather say so here than publish a weak recommendation.
Connemara sits at about 149.2 metres and has no closed hiking season. In all 11 scored months, temperature, rainfall and snow stay inside the limits at which we withhold a recommendation. Temperature moves 9.2 degrees across the year, from 6 in January to 15 in July.
Although the whole year clears the recommendation gate, the months are not interchangeable. Rain falls on about 56 percent of days in September, compared with 66 percent in August. Hikers prioritising drier conditions should start with September, then compare its temperature with July.
In January there are only 8 hours of daylight. We withhold December on that basis: day length, not weather, limits what can be walked here.
The strongest scored month is September: about 14 degrees in the hiking window, rain on 56 percent of days, and 13 hours of daylight.
Every figure comes from one selected ERA5-Land model grid cell at 53.50, -9.70, 149.2 metres, averaged over 1991 to 2025. It describes that point rather than every route in the region, and it is not a forecast. Wind is coarse 10 metre grid wind, not a statement about exposed paths or gusts.
