The Ozone Hole 2025
Antarctic Situation at 2025 August 10
Antarctic ozone
today:
The 2025
ozone hole is beginning to form. The
polar
vortex is growing and now covers 30 million square kilometres
(msqkm), a little larger than average.
The area
with potential PSCs began to grow from early May and covers some 27
msqkm, a little larger than the long term average and near its
maximum extent. The bulk of the ozone layer is now below the -78°C
Polar Stratospheric Clouds (PSC) formation threshold. The
temperature of the ozone layer is warmest around Antarctica and
declines towards the equator and the pole. Ozone values continue to
build around the continent and decline over it. They currently range
from a low of around 220 Dobson Units (DU) to a high of around 460
DU.
Antarctic Situation at 2025 July 21
Antarctic ozone
today:
The 2025
polar vortex is growing and now covers 25 million square kilometres
(msqkm).
The area
with potential PSCs began to grow from early May and covers some 24
msqkm, close to the long term average and near its maximum extent.
The bulk of the ozone layer is now below the -78°C Polar
Stratospheric Clouds (PSC) formation threshold. The temperature of
the ozone layer is warmest around Antarctica and declines towards
the equator and the pole. Ozone values are now building around the
continent and are lower over it. They currently range from a low of
around 240 Dobson Units (DU) to a high of around 430 DU.
Antarctic Situation at 2025 July 14
Antarctic ozone
today:
The 2025
polar vortex is growing and now covers 25 million square kilometres
(msqkm).
The area
with potential PSCs began to grow from early May and covers some 25
msqkm, close to the long term average. The bulk of the ozone layer
is now below the -78°C Polar Stratospheric Clouds (PSC) formation
threshold. The temperature of the ozone layer is warmest around
Antarctica and declines towards the equator and the pole. Ozone
values are now building around the continent and lower over it. They
currently range from a low of around 240 Dobson Units (DU) to a high
of around 400 DU.
Antarctic Situation at 2025 July 7 Antarctic
ozone today:
The 2025 polar vortex is
growing and now covers 23 million square kilometres (msqkm).
The area with potential PSCs
began to grow from early May and covers some 22 msqkm, close to the
long term average. The bulk of the ozone layer is now below the
-78°C Polar Stratospheric Clouds (PSC) formation threshold. The
temperature of the ozone layer is warmest around Antarctica and
declines towards the equator and the pole. Ozone values are now
building around the continent and lower over it. They currently
range from a low of around 240 Dobson Units (DU) to a high of around
430 DU.
Antarctic Situation at
2025 June 23
Antarctic ozone today:
The 2025 polar vortex is beginning to form and has grown to
20 million square kilometres (msqkm). The area with potential PSCs
began to grow from early May and covers some 19 msqkm, a little
larger than the long term average. The bulk of the ozone layer
temperature is cooloing towards the -78°C Polar Stratospheric Clouds
(PSC) formation threshold and has passed it in the highest parts of
the ozone layer. The temperature of the ozone layer is now warmest
around Antarctica and declines towards the equator and the
pole. Ozone values are now building around the continent and lower
over it. They currently range from a low of around 240 Dobson Units
(DU) to a high of around 400 DU.
