Please post your record warmest and coldest Marches here, or if they're not easily available you can post this month's summary for your area.

Now that March is drawing to a close, or has already ended for some of us, I thought it would be good idea to have a recap of your city's/country's monthly data for March. How do they compare with your average and historical Marches?

I'll start with the UK.

According to the Met Office this March looks set to be the UK's coldest since 1962 - that's 51 years ago.
"From 1 to 26 March the UK mean temperature was 2.5 °C, which is three degrees below the long term average. This also makes it joint 4th coldest on record in the UK. Looking at individual countries, March 2013 is likely to be the 4th coldest on record for England, joint third coldest for Wales, joint 8th coldest for Scotland and 6th coldest for Northern Ireland."
MARCH TOP 5 COLDEST IN THE UK:

1. 1962 1.9C
2. 1947 2.2C
3. 1937 2.4C
4. 1916 2.5C
5. 1917 2.5C

Well my hottest march was 1938. I believe last year we recorded the 4th warmest.

My first 20c weather last year occurred 24th march. This march I have not exceeded 9c!

N. Ireland was the second warmest place in the UK after southern England.

The UK has also just experienced record low temperatures for Easter Day. From today's Guardian:

"
The UK has recorded its coldest Easter Sunday for more than 50 years, with overnight temperatures dipping to below -12C in Scotland. The Met Office confirmed it had registered a temperature of -12.5 in Braemar, Aberdeenshire, in the Scottish Highlands. With modern records dating back to 1960, Sunday's freezing weather beat the previous record of -9.8, set in 1986.
The freezing temperatures, deep snowdrifts and bitter easterly winds stand in stark contrast to last year's mini-heatwave, when the mercury in Aboyne, Aberdeenshire, reached 22.9C on 26 March.
The Met Office said the month of March still looked set to be the coldest since 1962 and the fourth coldest since 1910."

The media is confused regarding the coldest March. The CET series shows 1962 having a much higher mean figure than quoted, 2.8C actually. I take it the 1.9C figure is the UK-wide figure.

That's right - the papers are referring to the national (i.e, UK) record, and not the CET (Central England Temperature) series, which goes back much further - all the way back to the mid-17th century. The UK national record only goes back to 1910.

anywhere I experienced? Or just my current location?

As I suspected, the coldest March on record here was a long time ago, 1916 with a mean of 26.84°F (-2.9°C). Max/Min was 36.7°F/17.0°F (2.6°C/-8.3°C), similar to a typical February. Warmest was in 1946 with a mean of 44.50°F (6.9°C), just 0.1°C warmer than March 2012. Max/Min of March 1946 was 57.5°F/31.5°F (14.2°C/-0.3°C).

Coldest March I experienced was in upstate NY with a mean of 27.0 (-2.3°C). Total snowfall of 15.4 inches that month.

As someone else has pointed out, the figure quoted by the British media refers to the UK national record which only dates back to 1910 and is not the same as the Central England Temperature (CET)
series, which dates back to 1659. These daily, monthly and seasonal temperatures are representative of a roughly triangular area of the United Kingdom enclosed by Bristol, Lancashire and London (view map).

Wikipedia's intro on the CET (my emphasis):

"The Central England Temperature (CET) record is a meteorological dataset originally published by Professor Gordon Manley in 1953 and subsequently extended and updated in 1974, following many decades of painstaking work. The monthly mean surface air temperatures, for the Midlands region of England, are given (in degrees Celsius) from the year 1659 to the present.
This record represents the longest series of monthly temperature observations in existence. It is a valuable dataset for meteorologists and climate scientists. It is monthly from 1659, and a daily version has been produced from 1772. The monthly means from November 1722 onwards are given to a precision of 0.1°C. The earliest years of the series, from 1659 to October 1722 inclusive, for the most part only have monthly means given to the nearest degree or half a degree, though there is a small 'window' of 0.1 degree precision from 1699 to 1706 inclusive. This reflects the number, accuracy, reliability and geographical spread of the temperature records that were available for the years in question....

For recent years there are two versions of the series: the "official" version maintained by the Hadley Centre, and a version maintained by Philip Eden which he argues is more consistent with the series as originally compiled by Manley."
