No! It is a myth that the northern lights happen only when it's cold. They happen year-round and since there is more darkness to see them in the winter people associate the cold winter with the auroras. August and September is a great time to see the Aurora while wearing a T-shirt and shorts!
FAQ
Does it have to be COLD to see the northern lights?
How long do the northern lights last?
Anywhere from 10 minutes to all night long, depending on the magnitude of the incoming solar wind. "Coronal holes" consistently produce nice auroras but big solar flares and CMEs-coronal mass ejections are responsible for global-wide aurora displays…the BIG shows!
When are the best months to see the northern lights?
Statistically, springtime (March/April) and autumn (September/October) contain the most "geomagnetically disturbed days" which means more aurora activity...although you're bound to see the lights in October, November, December, January and February if you spend enough time looking up.
In Yukon, it's dark enough to see the northern lights from about August-through-April. During May, June & July it's just too bright in to see them in the "Land of the Midnight Sun."
