I love winter in LA. It's certainly not terribly cold, although it can get down to near freezing at night and most older buildings aren't built with insulation, so heating can be expensive- I don't use mine.
What I really like is watching people at this time of the year. You'll see natives pulling out parka when it's a little over 60º while tourists from places like Wisconsin are in t-shirts and flip-flops.
This is the time of the year that it rains. Rain is greeted here as, say Tokyo regards the arrival of Godzilla. Action McNews blares headlines about "Storm Watch 2013" while darkly warning about the impeding storm as if it were a shower of man-eating clams rather than water.
Granted, storms here can be fraught. We've had mudslides, trees uprooted, and flooding. Traffic will come to a stand-still because half the people on the roads will go three MPH while the other half will go 20 miles over the limit, presumably because they have not been informed that automobiles are not water soluble.
But the main thing that I like about it is how clean and clear the air is here after the rain, and that I can see snow on the mountains to the east.
From the comfort and safety of the 65º temps on Santa Monica and Cañon...
