The coldest and the hottest month in recording history in your city? (records, temperatures)

[Max96]

Previous winter months (December 2011 and January 2012) were warm but very cloudy, although it was snowing in October 2011.

Washington, D.C.'s hottest month was July 2011 at 84.5 °F, with 93.6/75.4 °F, both the warmest, while the coldest was January 1918 at 23.7 °F (too lazy to reference the hi/lo ). For Pittsburgh the warmest month was July 1887 at 80.3 °F and the coldest January 1977 at 11.4 °F. Again, not going to reference the hi/lo for those two, but given the margin between Jan '77 and the next coldest month, Jan '40, is 6.0 °F, it would be safe to assume the hi/lo for Jan '77 are both the coldest; same cannot be said for Jul 1887

Maybe July of 2006

Los Angeles (inland around DTLA, East LA, Downey, Cerritos) averaged 98F

For Bingley:

Coldest was February 1986 (unfortunately there's no data for January 1963, which would likely have been colder):

Average high: -1C
Average low: -4.1C
Average: -2.6C

Hottest was July 2006:

Average high: 24.1C
Average low: 12.4C
Average: 17.9C

The average high of -1C in February 1986 is very impressive considering our climate, and is the only month on record since 1973 when the average high was below freezing - even December 2010 only managed an average high of 0.8C because of the mild interludes.

You averaged 23.4C over a whole month at 59N? Very impressive. Our national figures are based on a triangle centred roughly around 52-53N in the middle of the country, so quite a lot further south than Estonia, but our warmest month was only 19.7C in July 2006, though we had a 30-day period in July-August 1995 that averaged 20.2C. If I have it correctly the warmest daily mean ever recorded at the national level in our whole history was only 25.2C.

Using the same national dataset the coldest month was -2.3C in January 1963, though if we are trusting 18th-century recording methods then January 1795 came in at -3.1C.
