Snow days at Romania’s ski resorts, winter by winter since 2004
Semenic: snow days in every winter since 2004
Semenic: in winter 2025–26, the 1 km satellite map showed snow on the runs on 53 days between December and March. Since 2014, on the same map: 63 days a winter on average, from 24 to 100.
Here the 4 km and 1 km maps differ by 18 days a winter on average, so a comparison with the first decade would be uncertain.

A resort means its alpine ski runs in OpenStreetMap. For each map cell, the length of run passing through it was measured; a day counts as “snowy” when cells marked as snow-covered hold at least half the length of the runs. Bâlea Lac has no mapped runs and is a single point at the lake. Durău and Cavnic have few mapped runs.
