Skin weather in Honolulu
Honolulu is a high-UV city all year, near the equator and often cloudless: sunscreen is a morning habit, not a beach item, and the humidity means lighter textures suit most skin.
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.
