Skin weather in Denver
Denver is dry: indoor and outdoor humidity sit low most of the year and the altitude adds UV. Skin loses water faster here than the thermometer suggests; a humectant under a cream, and sunscreen even in winter.
How the index works
MET Norway gives a clear-sky UV index for each hour; cloud takes up to 70% of it away, so the number here is for the sky you have. The WHO categories: low 0–2, moderate 3–5 (sunscreen for time outside), high 6–7 (sunscreen on every uncovered part, reapply), very high 8–10 and extreme 11+ (shade and cover between 10 and 4). Dry air under 30% humidity and cold wind are the other two things the day does to skin.
