January in Zion National Park was a winter wonderland. The day before had a beautiful contrast of snow and red rocks. Daytime temperatures were cool but bearable. Expect cold nights and changeable weather.
HugoFebruary in Zion National Park was surprisingly pleasant, with mild temperatures and sunny days. Ideal for hiking, but not for the typical "sunbathing on the beach." Some snow fell, making the landscape picturesque.
