Sydneysiders may be wondering what happened to spring, with temperatures struggling to reach 20 degrees during the first week of October.

Extensive cloud cover, occasional showers and dominant southerly winds have led to cooler daytime temperatures, Josh Fisher, senior meteorologist at Weatherzone said.

This has been the case since the long weekend, which was marked by strong and cool winds, he said.

The city has struggled to pass 20 degrees just once during the first five days of the month and has also recorded rainfall on each day.

The average in the city is running at 19.1 degrees, which is 3 degrees lower than the average.

However, this does not compare to October 2009 when Sydney experienced nine consecutive days below 20 degrees.

The western suburbs have been just as cool as the city.

Penrith only just snuck up to 20.2 degrees today, with the previous four days remaining in the teens. Penrith's average maximum temperature so far this month is running at just 18.8 degrees, a whopping seven degrees lower than the usual October value of 25.8 degrees.

It is the first time in 16 years of records that Penrith has recorded five consecutive days at or below 20 degrees in October, Alex Zadnik, meteorologist team leader at Weatherzone, said.

The grey weather will continue into the weekend as another low pressure trough drifts over the state, Mr Fisher said.

This trough will maintain mostly cloudy skies with occasional showers and even thunderstorms, although a clearing is possible on Sunday.
