Sydney continues to miss out on the heat as most of southern Australia
swelters this week.
Some southern cities are struggling through an extended hot spell this
week, with both Melbourne and Adelaide likely to reach 30 degrees for
at least 10 consecutive days.
Despite this stifling weather in the nation's south, Sydney is
unlikely to break its seven-week run of days below 30 degrees any time
The last time Sydney reached 30 degrees was in mid-January, when the
city hit 45.8 degrees, its hottest day on record. This was also the
8th day of summer above 30 degrees, and the last.
The temperature has not reached 30 degrees in Sydney since that day, a
notable contrast to all of the other southern state capital cities.
During the 28 days of February, Perth reached at least 30 degrees on
20 days, Adelaide and Melbourne on 14 days, Canberra six days and
Hobart five. This was equal to the record for that month in both
Hobart and Melbourne.
Sydney's missing late summer heat has been due to a dominance of high
pressure over the Tasman Sea from late January, which resulted in
persistent onshore winds along the NSW coast. This maritime air acted
to hold the season's hot air masses inland, moderating daytime
temperatures in Sydney.
This week will see Melbourne set a new record for the longest run of
days over 30 degrees in March, while Adelaide's run of heat only will
have only been exceeded twice in 127 years of records.
Those living in Sydney will have to make do with a familiar run of
days in the mid-to-high 20s, which is still pretty warm for this time
of year. If the city reaches at least 25 degrees for seven consecutive
days it will be its longest March warm spell in three years. It only
has three more days to go.
