I received an email from someone who had read my article on the amazing cloud formation called the Sierra Wave, and wanted to know the best time to sight one “in the wild.” (you can access the full article here). With all of my hiking and cloud watching, I have only been lucky enough to see the wave once, although smaller wind formed lenticular clouds frequently occur in the high country. The winter months provide the best conditions for wave formations, yet the cloud’s mighty crest can loom over the Sierras anytime of year. My sighting occurred in August, during an intense fire season, which had probably wreaked havoc on normal summer conditions. My best advice for a wave sighting: spend lots of time in the Sierras
