How often does your city experience 15C+ temperatures in winter? (record, days)

[Infamous92]

NYC averages a week's worth of 15C+ temps per winter.

Here we reach 15C on average about 2 times per winter month. If it was 14C, then the average is at least 3 times per winter month. - In Colorado

Lol, in a moment of genius I hit never when it clearly is opposite. It is said that in the tropics, night is the winter. Using that definition, still it has always hit above 15c. Average low year round is around 24-25c. Record low is 17c.

I live in Kuwait City and per-neer every dang sunny afternoon, even in Dec/Jan/Feb gets over 15C. Often nights a bit cooler than 15. Only rare cloudy days during a cold front coming down from Russia, through Iraq, and you'd have a high below 15, a few days a year. Of course, the flip side of the coin is how many Summer days over 50C? Way too many!

London usually gets a couple of days each winter.

[mar89]

6 days each winter on average.

Pretty often. 15C is only about a degree warmer than the winter average maximum, and a warm month will have a daily average of 15C or higher.

That 14.7C was on the 13th, so 15C in February is theoretically possible.

We average 7 days in the three winter months at 59F or above. 3 in Dec, 2 in Jan and 2 in Feb over the last thirty years.

Our avg high is lower than yours in winter, but our standard deviation is a lot higher.

1 or 2 days per winter on average I would say.
In the warmest cities, Lisbon and Faro it's around 60% and 70% of the time

It's extremely rare here. December and January have never seen a high above 15°C, but February has.
Last time where it has been officially above 15°C was in February 2002 when 15.3°C was recorded (which is also the record high), though inner city and further away from the shore, several thermometers recorded 16-17°C that day.

So i would say February maybe every few decades.

December, maybe once in a hundred years (records began in 1949 and the all time high since then was 14.0°C in 1977)

January, even more unlikely (record high for this month is 13.1°C) but surely not impossible.
