WINTER SUN HALO
WINTER SUN HALOA quiet frozen lake.
One white sun.
And a perfect ring of color drawn into the cold air.
This is a sun halo—most often the 22° halo—made when sunlight passes through countless tiny ice crystals floating high in thin clouds (usually cirrostratus). Those crystals act like little prisms, bending the light so it spreads into a circular ring, with red on the inner edge and bluish tones toward the outside. Cold, clean winter air and a low sun can make the colors look extra crisp.
A detail people miss: the halo doesn’t mean “storm right now,” but it often hints that moisture is moving in aloft, so weather can change later (especially if the thin cloud layer thickens).
Where you can see that:
Look for it in cold regions or high elevations—Alaska, Canada, Scandinavia, the Rockies, or anywhere with a chilly day + thin milky high clouds. Open flat horizons (frozen lakes, plains, beaches) make it easier to spot the full ring.
