Sydney has faced a hot and record breaking day with Penrith reaching the highest temperature ever recorded in the Greater Sydney region.
Penrith shot to 47.1 degrees just before 2pm with the Bureau of Meteorology confirming it was the highest reading ever recorded at the station.
How to cope in the heat
Globally, more people die from heat than from bushfire. How well prepared are we for another scorching summer?
Weatherzone confirmed that it was also the highest temperature ever recorded in the Greater Sydney region with records in the area stretching back to 1859.
The city reached its highest reading just after 1pm, when a temperature of 43.4 degrees was recorded at Observatory Hill.
The last time the mercury rose so high in the CB was in 2013 when Sydney reached 45.8 degrees on January 18th, the hottest Sydney day on record.
On Sunday, the city was originally forecast to hit 40 degrees, but shot past that before midday.
Penrith has had the highest temperature recording in the state on Sunday with a high of 46.5 degrees recorded at 1:47pm.
According to Blair Trewin, senior climatologist at the Bureau of Meteorology, the previous hottest Ashes Test day appears to be a 43.1 degree day during the Adelaide Test between Australia and England back in 1908.
The SCG is about midway between Observatory Hill and Sydney Airport. The former has already reached 43.4 degrees and the latter 43.7 degrees.
The Sydney International tennis tournament organisers forced players off the court at 10am when temperatures courtside exceeded 40 degrees.
Sydney got off to a hot start on Sunday with many parts of the city racing above 30 degrees early in the morning.
Penrith was sitting at 30.4 and Campbelltown was recording a temperature of 31.1 degrees at 9am.
The city had reached 29.8 at the same time, rising above 30 degrees just 10 minutes later.
Springwood, just west of Penrith, recorded one of the hottest temperatures early in the day with a recording of 35.2 at 9am.
Surfers were quick to find the water this morning, hitting the waves just as the sun rose.
It was a relatively warm start to the day even at dawn as the mercury failed to dip below 22 in Sydney overnight.
A cool change is expected to move west later in the day, hitting the coast in the late afternoon and reaching the west in the early evening.
There is a slight chance of a thunderstorm for Sydney too although no weather warnings have been issued as yet.
The hot weather, combined with strong winds, means there is a chance for bushfires to spread out of control.
The Rural Fire Service has issued a total fire ban for the Greater Sydney and Hunter Regions, with Sydney being given a severe fire rating.
NSW Rural Fire Service Deputy Commissioner Rob Rogers said that smokers needed to be particularly aware on days with total fire bans.
“One of the common things we see people do is throw cigarette butts down,” he said. “People should understand that the fine is around $1,300 if we catch you throwing a lit cigarette in a total fire ban.”
The NSW Office of Environment and Heritage has issued an Air Quality Forecast alert of poor, with ozone levels higher than normal.
This means those with respiratory problems such as asthma will need to be extra cautious during the hot weather and keep their reliever medication nearby.
