It's better than being cold.
It got down to 12C (50F) last night.
I hate winter so much.
I imagine it was warmer than 12C in the day? That's perfect - throw the windows open, slip a comforter on, fall asleep like a baby.
That said, a perfect summer night here, imho, is right around 60-65ºF - daytime around 75-80ºF. That's the perfect day. Low humidity, at least.
Our winter has nights in the single-digits, like 5ºF (that's negative for you). I don't like our winters. Layering is great and all, but I hate shivering - I also hate sweating and I do that a lot when it's upwards of 80ºF.
