Climbing Conditions

Climbing Conditions helps you find the best days and places to climb at crags across Europe.

On the map, the number on each crag marker is a condition score (0–100) for the day you selected — higher means better expected rock climbing conditions. Tap a crag for detail, charts, and a 14-day outlook.

How scoring works

Each score estimates how good climbing conditions are likely to be at that crag on a given day. The model combines:

• Weather — temperature, humidity, wind, rain and snow, cloud cover, and recent drying history
• Sun and aspect — how much sun hits the wall and when (local daylight)
• Rock type — limestone, sandstone, granite, and other types behave differently in wet, humid, or cold weather
• Safety gates — hard limits for clearly bad situations (e.g. wet sandstone, storms, ice)

Scores are computed hour by hour in local crag time; the daily headline is the best hour that day. Charts on the crag page show how conditions change through the day.

Features

• Map view with condition scores on crag markers
• List view with filters (rock type, minimum score)
• Separate scores for sport, trad, and boulder where available
• 14-day condition forecast per crag
• Weather trends and score charts on crag detail pages
• Optional location to center the map on you

Coverage focuses on European crags, with more areas added over time.

Condition scores are informational only. Always use your own judgment and local knowledge. Climbing is inherently risky.
