We're still in spring I think. Or autumn, I'm not sure. Definitely not winter - that seems to arrive about the third week of July.
The best time of day is "now" (and I must remember to take my own advice sometime). Even when it's -1°C out there...
I think summer begins in Decemeber. Then we will whinge about it being too hot to run. Give me winter any day, though Mt Korong day did test me.
