Of course, my comment was on cloud cover above water, near the poles, including the water surrounding Antarctica, which has frequent snowfall including as we speak. Take a look at current satellite imagery of the area surrounding Antarctica: https://www.windy.com/-Satellite-satellite?satellite,-63.744,44.517,4 https://www.windy.com/-Satellite-satellite?satellite,-63.744... Cloud cover is more common over ocean water than on land. Also, Antarctica's cloud cover is larger in the winter than in the summer: "The seasonal cycle of cloud cover is found to range from 45%–50% during the short summer to a relatively constant 55%–65% during the winter.

You can find similar studies on the cloud cover above exposed water in the Arctic. It doesn't matter how variable clouds are, what matters is an average over a long period of time. Clouds have a far more dramatic effect on global temperatures, because they have the ability to reflect absorption of solar energy in the hottest parts of the planet (the tropics), where ice cannot exist. They can and do form over most of the ocean water which covers 2/3 of the planet's surface. Average cloud cover over ocean water is 90%! Some clouds scatter light. Some are extremely effective at reflecting light into space. Depends on zenith angle of the light (based on latitude), the altitude of the cloud, water content and shape and thickness overall. https://www.researchgate.net/publication/334183298_High_cloud_coverage_over_melted_areas_dominates_the_impact_of_clouds_on_the_albedo_feedback_in_the_Arctic https://www.researchgate.net/publication/334183298_High_clou...
