1990年的南极臭氧洞在深度、持续时间和面积上与1987年的臭氧洞相匹配。在空洞形成阶段（8月），臭氧总量值是有记录以来最低的。下降率与1987年的记录大致相当，并在1990年10月4日达到最低值125个多布森单位。10月份臭氧总量平均值略高于1987年。与1987年一样，1990年10月中旬至11月期间，洞内的臭氧总量缓慢而稳定地增加。臭氧空洞的破裂是有记录以来最晚的一次（12月初），极地上空的臭氧值一直持续到12月，创下了12月极地臭氧平均值的最低纪录。早春的气温接近平均水平，但春末的气温低于正常水平。1990年早春的气温比1987年早春的气温要高得多。
The 1990 Antarctic ozone hole matched the record 1987 ozone hole in depth, duration, and area. During the formation phase of the hole (August), total ozone values were the lowest yet recorded. The decline rate approximately matched the record 1987 decline, and reached a minimum of 125 Dobson Units on October 4, 1990. October total ozone averages were marginally higher than 1987. As during 1987, the 1990 total ozone values within the hole slowly and steadily increased during the mid-October through November period. The ozone hole breakup was the latest yet recorded (early December), with low ozone values persisting over the pole through December, setting a record low for December average polar ozone. Temperatures were near average during the early spring, but were below normal for the late-spring. Temperatures in the early spring of 1990 were substantially warmer than those observed in the early spring of 1987.
