Ora (wind)
The Ora ( Italian for 'hour') is a southerly wind on Lake Garda and in the Adige Valley .
If the air of the Alps, which is cooled down at night, is heated by the sun during the day, this warm air rises on the south side of the Alps and draws the comparatively cool air over Lake Garda. That is why the ora usually begins around noon and subsides in the late afternoon when the sun's rays decrease.
At night the conditions are reversed and the cold air falls from the mountains to the lake, where it is warmed up by the warm water and rises. The resulting north wind is called Pelér or Vento .
The Ora is usually a little weaker than the Pelér and usually reaches 4 to 5 winds . It blows strongest at the narrowest point of Lake Garda at the entrance of the Ponale near Riva del Garda . In Riva itself, the Ora rarely comes through due to various wind shadows, which is why windsurfers prefer the Torbole located next door .
In South Tyrol, the Ora can be felt very well on Castelfeder , and thanks to this wind, Lake Kaltern is also a popular lake for surfers and sailors.
