No early let-up for Sydney’s overnight shivers as cold records tumble


Winter's grip tightened on Sydney and much of NSW, plunging some regions to record lows, with another bout of chill on the way.

Sydney's overnight low of 5.1 degrees at Observatory Hill on Sunday was the lowest July temperature since 2007. The most recent lower overnight reading was August 5, 2015, the Bureau of Meteorology said.

Camden was colder still, with -3.8 degrees at its minimum, and Richmond with -4.3 degrees. For both sites, it was the lowest overnight temperature since June 2010.

Inland regions broke records, such as Bathurst's -8.1, a new low for any month.

The defence facility at Marrangaroo near Lithgow was the coldest spot in the state with a regular gauge, dropping to -11.1.


A soil gauge in Orange gave a colder reading, or -14.3 degrees. That was the coldest Orange morning by that measure in 43 years of records.

"We've had a strong high pressure system over the state overnight, bringing clear skies and dry conditions, allowing temperatures to drop," Jordan Notaro, a bureau meteorologist, said.

"At the moment we're expecting another cold morning [on Monday], with temperatures relatively similar to what we saw around this morning."

On current forecasts, the bureau expects an overnight low of 5 on Monday in the city, well below the July average minimum at Observatory Hill of 8.1 degrees.

Inland regions will again be hit with frosty weather on Monday, with -3 predicted for Richmond.

Sunny days

Daytime temperatures, though, will continue to bring relief, as sunny conditions lift the mercury to more comfortable levels.

Sydney's maximum is predicted to reach 18 degrees on Sunday and Monday, with a top of 22 tipped for Tueday and Thursday. The long-run maximum average for July is 16.4 degrees.

Fog is expected in Sydney's west again on Monday, as well as areas of morning frost and light north-westerly winds in the afternoon.

Sydney could look forward to a mostly sunny week with only patchy cloud and little chance of rain. The morning fog and light winds are likely to continue to be a feature for most days.

Temperatures should then drop again by next weekend in the wake of a frontal system.
