In 2010, the temperatures were slightly above the norm; the consequence was an average phenological year. The spring however started late at the time of hazel flowering, because of the low temperatures registered until mid-March. The following spring phenological phases were observed on average dates. The needles of the spruce showed a tendency towards late development. The phenological summer 2010 can be considered as normal or slightly early. During summer, the temperatures were sometimes above the norm. As it is frequently observed, the phenological autumn was inhomogeneous: the phases were either early or late, depending on the station.
