2020 Antarctic ozone hole is large and deep | World Meteorological Organization

The annually occurring ozone hole over the Antarctic is one of the largest and deepest in recent years. Analyses show that the hole has reached its maximum size.

The 2020 ozone hole grew rapidly from mid-August and peaked at around 24 million square kilometres in early October.  It now covers 23 million km2, above average for the last decade and spreading over most of the Antarctic continent.
