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."
Aurora is a luminous glow of the upper atmosphere caused by energetic particles entering the atmosphere from above.
This definition differentiates aurora from other forms of airglow, and from sky brightness that is due to reflected or scattered sunlight. Airglow features that have "internal" energy sources are more common than aurora. For example, lightening and all associated optical emissions like sprites should not be considered aurora.
On Earth, the energetic particles that make aurora come from the geospace environment, the magnetosphere. These energetic particles are mostly electrons, but protons also make aurora. The electrons travel along magnetic field lines. The Earth's magnetic field looks like that of a dipole magnet where the field lines are coming out and going into the Earth near the poles. The auroral electrons are thus guided to the high latitude atmosphere near each pole. As the electrons penetrate into the upper atmosphere, the chance of colliding with an atom or molecule increases the deeper they go. Once a collision takes place, the atom or molecule takes some of the energy of the energetic particle and stores it as internal energy while the electron goes on at a reduced speed. The process of storing energy in a molecule or atom is called "exciting" the atom. An excited atom or molecule can return to the non-excited state (ground state) by sending off or emitting a photon, i.e. by making light.
It’s possible to see the Northern Lights through a few scattered clouds, but if there are too many, the view might be blocked completely.
The AuroraCentre is located perfectly in the most 'dry' region of the Yukon which results in less cloud coverage then any other location. Typically we only see 1-3% completely cloudy night sky at the AuroraCentre throughout the year.
Even if the sky is cloudy, rainy or if snow is falling during the day we will always start our Aurora Viewing tour as scheduled to ensure our guest don't miss an opportunity to see the Aurora Borealis when the clouds break (which they most often do!). Typically the weather changes around midnight in the Yukon and even a cloudy evening can turn into a clear night.
The Aurora Borealis is a natural phenomenon and relies on the level of aurora activity and weather conditions. We provide one of the best locations to enjoy the Aurora Borealis with the comfort of heated a cabin, yurts and teepees, with the company of knowledgeable tour guides.
Since the level of aurora activity and weather conditions is out of our control, unfortunately, we can't offer refunds or re-bookings.
