Chinook Days Festival

603 North Main Street
Spearfish, SD 57783

It was 76 years ago January 22, 1943 when Spearfish, SD. set and still holds the record for fastest temperature change.

That day started out very cold in Spearfish, and at 7:30 am MST the temperature recorded was -4°F. At that time Chinook winds picked up speed and two minutes later at 7:32 am the temperature rose to +45° F. This was a 49° increase in just two minutes that is a record that still stands.

Join us for a week long winter festival in Spearfish, SD celebrating this world record event.
