Catch Night-Shining Clouds: Prime Viewing Season Begins
Updated June 01, 2025
The season for spotting noctilucent clouds, also known as “night-shining” clouds, is here. These high-altitude formations offer a spectral display during summer months.
Unlike typical clouds that frustrate astronomers, noctilucent clouds provide a unique spectacle. These wispy, icy formations glow with a blue hue, reflecting sunlight in the hours after sunset and before dawn.They exist roughly 50 miles above the Earth’s surface within the mesosphere, far higher than ordinary clouds.

The best viewing window stretches from late May to mid-August, with June and July offering peak opportunities. Look to the northern latitudes, between 45 and 80 degrees north, about 90 to 120 minutes after sunset or before sunrise. This range includes states such as North Dakota, Montana, and Washington.
Royal Museums Greenwich reports that noctilucent clouds are appearing more frequently at lower latitudes. scientists believe this shift is due to climate change and increased rocket launches.
EarthSky.com notes that these clouds form as warm, moist air rises during summer. As the air cools in the upper atmosphere,ice crystals develop around dust particles,some of which are meteor remnants,volcanic ash,or pollution.

Their high altitude and icy composition give noctilucent clouds a high albedo, allowing them to reflect sunlight even after the sun has dipped below the horizon.
What’s next
As summer progresses, continue to monitor the twilight skies for these elusive, shimmering displays. Increased awareness of noctilucent clouds and their potential link to climate change may spur further research into their formation and behavior.
