SUMMARY
Clouds are not opaque to ultraviolet (UV) light, which is the primary reason individuals can get sunburnt on cloudy days. While clouds block a significant portion of UV radiation, they do not eliminate it entirely, allowing some UV rays to penetrate and cause skin damage. The relationship between cloud cover and UV exposure is similar to that of visible light, as clouds allow some light to pass through, enabling visibility even on overcast days.
PREREQUISITES- Understanding of ultraviolet (UV) radiation and its effects on skin
- Basic knowledge of atmospheric science and cloud formation
- Familiarity with the electromagnetic spectrum, particularly the visible and UV light ranges
- Awareness of sun protection measures and their importance
- Research the effects of UV radiation on skin health
- Learn about different types of clouds and their impact on UV exposure
- Explore effective sun protection strategies for varying weather conditions
- Investigate the electromagnetic spectrum and the properties of UV light
This discussion is beneficial for dermatologists, outdoor enthusiasts, and anyone interested in understanding the effects of weather on UV exposure and skin health.

Because clouds are not opaque to ultraviolet light, of course.

To expand a bit;
Clouds are not opaque to visible light either. Ever notice how on a cloudy day, you can still see? The amount of light in the visible range that gets through the clouds is not zero. The UV radiation that does the famage to your skin is close to the frequencies of visible light, so the effect of clouds on these two forms of radiation is similar. Not much UV gets through, but some.
That's why the song "My Girl" can truthfully say, "I got sunshine, on a cloudy day..."
