So this is not the tropics by any means. And keep in mind that the coldest part of the day is usually about 20mins AFTER sunrise, and sunrise is around 7am in Sacramento in January, and 7:30 in Nogales. So unless you have a job/school that starts at 10/11 in the morning, YOU WILL BE OUT AND AWAKE DURING THE COLDEST PART OF THE DAY
Depends on where in winter we're talking about. A 20C/0C average in winter is definitely not possible this far north. Further south, say in Phoenix, winter days aren't very short anyway.
I know here in Atlanta we've had days in the mid 50s with the sun that actually feels pretty nice. The lowest noon sun angle in winter is about 33 degrees above the horizon. You can certainly feel it. I actually enjoy those days. Much more than 50s and overcast/wet.

Why are you shouting for? Calm the hell down. Everyone knows that the low temperature occurs after sunset - that's besides the point. Most of the day will probably feel warmer if the low is 0C and the max is 20C, vs a low of 7C and a max of 13C.

Sorry, I am using a smart phone, so can't do things like bolded type (or don't know how), was only meant for emphasis
There has never been a day like that in SF in July, matter of fact SF has never hit 7 C ever in July.
Last time I was in SF it was in the 90's.
As for the question posed by this thread, 20C-0C definitely feels warmer than 13C-7C. I was in Nogales, AZ this past thanksgiving (21C/-2C) and it felt far warmer than the days of 13C/7C I've experienced in Florida and other places.
It gets 20/0 in Austin in the winter a lot, as well as 13/7. Several examples of 32 degree low and 68 degree high for instance. Sometimes it can be 30 at night and 75 in the day if you get a good wind shift from north to south in the day.
I much prefer the 20/0 days. Dry arctic air with cold nights (need to use heat however at night) and nice warm days. 13/7 is kinda bland weather, and you need heat too.
Long term I wouldn't like the dryness of 20/0, but it breaks up the winter when we get weather like that.
Obviously a day with 13C max will feel much colder than a day with a 20C max regardless of the minimum.
20C/0C is a very rare combination here but it did happen in April 2007. There was a visible white frost in the morning but it soon lifted and warmed up rapidly resulting in a wonderful gloriously warm and sunny day.
13C/7C is typical of the dross we get in October. Doesn't feel remotely warm.
Rather astonished that many people find 13C/7C cooler, considering that 20C is still quite warm regardless.
7/13C feels cooler. From my experience, days with 0/20C temps tend to warm up quick with the sunshine and calm winds that characterize such conditions. 7/13C days are almost always cloudy with windchill. 0/20C is fairly common in Autumn, late winter and spring here.
It's actually not too uncommon to see such days late April in Sweden's inland.
This year we even had a 25/3 day in May at the coastline.
