Coldest morning of the year so far: minimum temperature of the air between the hours of (say) 4am and midday, that is colder than any previous morning this calendar year, as measured by a thermometer and reported in Celsius, Fahrenheit or Kelvin.
This is south-east Australia so it’s not going to compete in absolute terms with, say, south-east Wisconsin (I have strong memories of waking to -32F with a windchill of -75F) but frost is frost and old Australian houses are not winterised like equivalently aged American houses. It was a 4-blanket, 1-dog, night.
We get to scrape frost from the insides of the windows here. Generally from the end of December through to March. Old old house with old old windows. Though we never hit Wisconsin level “death cold”. I think our warmest night this year has been about 75°F ( just under 24°C).
Ioa, 1 dog equals about 10 blankets if the dog is the right size. Our new-to-us puppies are 65 & 75 lb each and generate enough body heat to power a small village steam plant. I’m hoping they will be as willing to share that heat in January as they are in July.
