The climate in Montana is varied. You have four seasons and each season has a different temperature. Summer is usually in the high seventies and eighties but can get into the nineties. Spring is full of suprises with warm temperatures in the sixties one day and then snow the next. Fall is warm to start and then goes back and forth between snow and fifties and sixties. Winter is long and snow comes and go the entire time. Temperatures can drop into the negative digits. Normal days may range in the twenties and thirties.
