Bureau of Meteorology meteorologist Jake Phillips said the high temperatures this holiday season are being caused by a slow-moving weather system dominated by high pressure over the Tasman Sea. It means we are likely to get warm weather for several days.
“The heat has been accumulating for a few days — we’ve had this warming trend since the second half of last week,” he said. “Warming will continue for the next few days before tapering off later this week.”
Phillips said the drop in temperature could bring some light showers over the turn of the year, but it would take a few more days for the forecast to firm up.
“[The warm temperatures] are a bit above average at this time of year and contrary to the cool weather we’ve had lately it seems a lot hotter,” he said.
Looking further ahead, the warm weather is set to continue bringing temperatures between 25 and 29 in the city by January 1st. In the western suburbs, it’s likely to be in the mid to low 30s through December 30, after which temperatures drop to around 25 degrees.
The warmer weather comes as climate phenomena that have led to wetter than average conditions this year begin to weaken. The La Nina event meant Sydney recorded its wettest year, with the city experiencing more than 2522 millimeters of rain, much more than the 1221 millimeter average. It took Sydney just 279 days to break its previous record of 2194 millimeters set in 1950.
This year the NSW SES has responded to 80,032 requests for assistance and carried out 3812 flood rescues. The areas that needed the most help were Forbes, South Lismore and Wee Waa. NSW SES Commissioner Carlene York said this year has been the busiest for the agency on record.
The Bureau of Meteorology notes that Australia’s climate has warmed by an average of 1.47 degrees since national records began in 1910. Also, the south-east of the country has seen a drop in rainfall of about 10 percent between April and October since the late 1990s.
