Historical climate at one selected model cell. Higher routes, sheltered valleys and exposed ridges can differ substantially.
Model elevation: 1,025 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: 37.9, -3.0
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.
37.9, -3.0 · 1,025 m
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.
Sierra de Cazorla sits at about 1,025 metres and has no closed hiking season. In all 10 scored months, temperature, rainfall and snow stay inside the limits at which we withhold a recommendation. Temperature moves 19.7 degrees across the year, from 7 in January to 27 in July.
Although the whole year clears the recommendation gate, the months are not interchangeable. Rain falls on about 6 percent of days in July, compared with 35 percent in April. Hikers prioritising drier conditions should start with July, then compare its temperature with July.
In July the hiking-window temperature reaches 27 degrees. We withhold July to August because sustained heat makes a walk a question of time of day and water, rather than of season.
The strongest scored month is May: about 17 degrees in the hiking window, rain on 28 percent of days, and 14 hours of daylight.
Every figure comes from one selected ERA5-Land model grid cell at 37.90, -3.00, 1,025 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.
