Comments on February 2002
February was a very mild month, the 5th equal warmest since 1850, exceeded only by 1903, 1990, 1945 and 1998 (by far the warmest February on record with a mean air temperature of 7.6°C). It was the 20th warmest winter record, a cool December bringing down what might otherwise have been a very warm winter. It was also a wet month: the 9th wettest February on record, though less wet than in 2001 and far less wet than 1941 when 152.5mm was recorded. However, the 12-month rainfall total remains well below the long-term average, while 3-month and 6-month totals are close to average. Despite the rain, it was sunnier than usual and also a windy month with a gust of 100km/hr on the 1st.
