Ozone (O3) is a highly reactive gas whose molecules are comprised of three oxygen atoms. Its concentration in the atmosphere naturally fluctuates depending on seasons and latitudes, but it generally was stable when global measurements began in 1957.

Ozone is a gas composed of three atoms of oxygen. Ozone occurs both in the Earth’s upper atmosphere and at ground level. Ozone can be good or bad, depending on where it is found.

Certain human-made substances had reached the stratosphere and disrupted the ozone layer to the point of depletion, creating an extremely thin section commonly known as the ozone hole. The hole formed at the South Pole due to the region’s unique meteorological and chemical conditions.

Seasonality plays a part: May through August are typically the strongest months, UV-exposure-wise. But, as the Sun Safety Alliance states, “UV rays reach Earth every day—including wintertime. Snow can reflect 85% to 90% of the sun’s UV rays.” So, lather up the SPF year round.
