Innsbruck has a humid continental climate using 0 °C (32 °F) isotherm or oceanic climate (Cfb) using the original −3 °C (27 °F) isotherm since it has larger annual temperature differences than most of Central Europe due to its location in the centre of the Continent and its position around mountainous terrains.
Winters are often very cold (colder than those of most major European cities) and snowy, although the foehn wind sometimes brings pronounced thaws.
Spring is brief; days start to get warm, often over 15 °C (59 °F), but nights remain cool or even freezing.
Summer is highly variable and unpredictable. Days can be cool 17 °C (63 °F) and rainy, or sunny and extremely hot, sometimes hitting 34 °C (93 °F). In summer, as expected for an alpine-influenced climate, the diurnal temperature variation is often very high as nights usually remain cool, being 12 °C (54 °F) on average, but sometimes dipping as low as 6 °C (43 °F).
The average annual temperature is 9 °C (48 °F).
