Sun and glare index / Milwaukee
Sun and glare in Milwaukee right now
UV 0 · Low UV: air 43°F, feels like 42°F, least sun 16:00–18:00.

- Low sun: glare off roads, water and glass; polarized lenses cut it
UV is MET Norway's clear-sky value with the hour's cloud taken out; the label is the WHO category. From 3 up, UV-rated sunglasses earn their place; glare (low sun, water, snow) is a separate question that polarized lenses answer.

Sun and glare in Milwaukee
Milwaukee has low UV in winter but real glare: snow reflects up to 80 percent of UV, so a bright February day on a white field can be harder on the eyes than July. Summer afternoons reach high UV; the low sun of early spring and fall is the driving-glare season.
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, high 6–7, very high 8–10, extreme 11+. Eyes take UV damage at any category over time (cataract and pterygium are the documented ones), so a UV400 lens matters more than how dark it is. Glare is reflected light and peaks with a low sun, water and snow; that is the polarized question, not the UV one.
