Maximum temperatures nationally were the coldest on record with a national anomaly of -2.19°C. Most of Australia recorded below average mean maxima with parts of the north and south of the country recording their coldest March on record. This was partly due to increased cloudiness across most of the country associated with the above average rainfall recorded throughout the month. March 2011 included some contrasts between the majority of Australia and the west and east coasts, which were the only areas that experienced above average daytime temperatures. Temperatures were coolest in the central part of Australia where rainfall was most abnormal, with maximum temperatures more than 3°C below average Similarly, drier conditions matched up with areas of above-normal maxima in western WA.
