As of today, out of season, returns ~November. Earth Exhibit tracks the live conditions and flags it the moment it is on.
A total cloud inversion at the Grand Canyon occurs when a layer of cold air becomes trapped at the bottom of the canyon beneath a warmer air mass above, creating a temperature inversion that fills the entire 1.6-km-deep gorge with fog and low stratus cloud.
The result is a vast, rolling sea of white clouds stretching from rim to rim, with only the canyon's upper edges and distant plateaus visible above the cloud deck.
The phenomenon transforms the familiar landscape into something resembling an ocean of cotton, with cloud tendrils spilling over viewpoints and occasionally parting to reveal glimpses of the Colorado River far below.
While partial inversions occur a handful of times each winter, a total inversion that fills the entire canyon is exceptionally rare, documented roughly once every few years.
Notable total inversions were recorded on November 29, 2013, December 11, 2014, and December 14, 2023.
