A weather question

Is it just me, or does this Brisbane winter seem to others to be colder at night and in the mornings than your average recent winter?  The days are still nice enough, for the most part (although even then, I have a sense that we have had slightly more cloudy, no sunshine days - like today.)  I just seem to have been feeling colder in the house this winter generally speaking.

Of course, in the Northern Hemisphere, things are in the opposite direction:
For the past month, Siberia has captured the world’s attention thanks to a climate change-fueled heat wave that caused temperatures in an Arctic town to crack 100 degrees in June and whipped up an outbreak of fires across normally frigid tundra. But an equally alarming situation is unfolding just north of Siberia’s shores: sea ice is crashing in a region that scientists consider to be the ice factory of the Arctic.
A new ice extent record in September is not certain, but the long term consequences of a lot of open sea north of Siberia is still likely to be significant:
Whether 2020 brings a new record for sea ice destruction or not, what’s happening this year will be significant. Most new sea ice formation in the Arctic occurs along the eastern half of Siberia’s north coast, where ice grows in the autumn and winter before being swept out to sea. Because there’s so much open water absorbing sunlight in the region right now, Serreze says it’s “very likely” that autumn ice formation will be delayed, which could have ripple effects going into next year.

Ultimately, more years like this could hasten Arctic sea ice’s long term, climate change driven meltdown, which matters far more than individual records.

“Everyone wants to focus on the minimum, but any amount of time the ice is at a record low is affecting arctic climate,” Labe said. “To me, that’s very significant.”
Here's the graph:
