The weather affects a mountain outing far more than it may seem. It not only determines whether it is worth heading out: it also influences the route, timing, water you need and the gear it makes sense to carry.
Checking a nearby weather station helps you understand what is really happening in the area. This is particularly useful before hiking in the mountains, where conditions can be quite different from those in a nearby town or in the general forecast for the province.
Map of mountain weather stations
Years ago, we found this map of weather stations in Spain, maintained by its creators, which brings together measuring points from public bodies, individuals and private companies, such as ski resorts and hotels.
If there is a station close to your route, you can check recorded data for the area, such as temperature, humidity or rainfall, and review how it has changed over the last hours, days, weeks or months.
It is important to understand what this tool offers: it is useful for checking observed data at a specific point, not for replacing a weather forecast. A station at a different altitude, on another aspect or a few kilometres away may record different conditions.
First, look up the area where you will be hiking and find the stations closest to your route. Click an icon to see the available stations; selecting one will open its page with the recorded data.
To make the check useful, focus mainly on these points:
Elevation and location: a station in a valley does not necessarily reflect conditions on a ridge, a pass or the higher parts of the route.
Recent temperature: this helps you check whether the night has been cold, whether there may be frost at higher elevations, or whether the heat is already building early in the day.
Precipitation: accumulated rainfall can help you anticipate mud, higher streams or slippery ground.
How the data is changing: a single reading says little. Seeing what has happened over the last few hours provides more context than looking at the current value alone.
Use it as a final check alongside the forecast, the official information available for the area and your judgement on the ground. In the mountains, it is wise to keep a margin and be prepared to shorten the route, change it or turn back if conditions are not favourable.
What gear to adjust for the conditions
Knowing the likely weather helps avoid both carrying too much and heading out with inadequate gear. It is not about taking less at any cost, but about choosing items that cover the real risks of the route.
In wet areas or in cold, damp conditions, a waterproof jacket and leg protection can make a difference. If snow, strong wind or low temperatures at higher elevations are possible, your safety margin should be greater.
On warm routes, it usually makes more sense to prioritise lightweight, quick-drying clothing and sun protection. For light or intermittent rain, depending on the terrain and exposure, an ultralight umbrella can be a practical alternative: it also provides sun protection and avoids carrying a heavier garment all day. However, it is less useful in strong wind, in very exposed areas or when you need both hands free.
The weather station does not choose your gear for you, but it provides a real-world reference to help you decide more clearly what to carry in your pack.
Another useful map for planning
If you are planning a route in the Pyrenees, you can also consult our map of unmanned and staffed mountain huts in the Pyrenees. Combining hut, route and weather information helps you plan your days and alternatives more effectively.
