UV through the year in Sterling Heights
This far north the sun sits low for much of the year, so UV in Sterling Heights is concentrated in the high-summer months and peaks in June, when the estimated clear-sky peak UV index reaches about 11 around solar noon. At that peak the noon sun reaches about 71° above the horizon. Each month below pairs the noon sun elevation with the estimated peak UV and how fast unprotected skin can begin to redden.

Frequently asked
- When is UV strongest in Sterling Heights?
- In Sterling Heights the sun rides highest around June, when the estimated clear-sky peak UV index reaches about 11. Within any day it peaks near solar noon — roughly 10 a.m. to 4 p.m. local time. It is also stronger at higher elevation and near reflective surfaces like water, sand, and snow.
- Can you get sunburned on a cloudy day in Sterling Heights?
- Yes. Up to about 80% of UV radiation passes through clouds, so you can still burn in Sterling Heights on an overcast day. The WHO notes that thin or scattered cloud offers little protection — check the UV Index, not the sky.
