-4C last night, +4C today, currently -1C.

Have to say it was an unusual sight to see frost lying at lunchtime in the shade. I can't remember many other occasions this happened in March.

Well I've now passed a new record minimum for here with regards to minima in March. My previous record minimum was -05.3C on both March 01st 2004 and March 04th 2006 but last night it fell to -05.7C! That is unusual for March - especially considering it's lower than anything I recorded in February.

The only times I have recorded a maximum of 5C or less with sunshine a feature were either when there was snow on the ground or there was a strongish wind from a cold source. Today however had none of them. :acute:

Though maxes today have been cold and generally have been all week, its nothing unusual, this is still the first week of March, we've only just left Feb when maxima of 0 degrees can still be quite common, its a bit liking being shocked with maxima aove 25 degrees in the first week of Sept which often do occur.

We've had lower maxima in recent Marches such as in 2006 and potent northlies even at the tail end of March can easily deliver maxima of 1-2 degrees and well into April.

Perhaps it doesn't seem quite right to be recording maxes of 3 degrees under brilliant March sunshine, whilst the sun is gaining strength, any flow from a still very cold continent with low dewpoints and very dry air is not going to be tempered by the sun.

13th March 1845, Greenwich recorded a maximum of just -4C and the following night a minimum of -10.5C

Values notable for January let alone mid-March.

Good to see a bit of perspective. Certainly nothing incredible about my max of 6.1c.

Anyway tonight does look like being notably cold for March, currently -4.4c, I guess -9c would be a pretty cold night for March. The very low RH and very dry ground here should see it around that by dawn.

Certainly a notable cold snap for many, more so for the low minima than the low maxima, but at the same time, not exceptional for this early in the spring. The first weeks of Marches 2001 and 2006 were often colder than this over most of the country.

What is unusual about this instance is that it's associated with high pressure rather than a full-on blast of cold air like in the 2001 and 2006 cases.

It seems like the current sunny and cold scenario is the result of the Arctic High ridging south.

Also these cool anticyclonic spells are not exclusive to the winter and spring months. They can also occur in the autumn and summer months like August 1993.

Max of +3.5c yesterday - which is my lowest ever March maxima (records from 2003)

This morning fell to -5.9c which is my 3rd lowest March minima and the latest date on which temp has fallen below -5c

Its funny how these things work out. Anyone remember February 2008? That was incredibly sunny with the kind of clear skies and unbroken sunshine we have currently enjoyed. However maxima got as high as 16C for Manchester and that was the 12th of February. Yesterday was 10C colder even though it is 3 weeks later in the calendar than the 12th of February and the sun is obviously higher and stronger. Shows how much impact different airmasses can have.

Or may be not so cold! Temperature stabilised after midnight, min -5.5c was unremarkable for March really.

Had colder already this month down to -7c last week.

I doubt that those are really so unusual in early March. We are barely a week out of February when -10c is easily achieved. March can get minima virtually as cold as in any winter month, for example March 7th 1947 when -15.6c was recorded in Covenrty.

Indeed Mr Data it all depends on the airmasses. The high from February 2008 was warm and sunny due to an early Continental Tropical air plume:-

Whereas the current high is cold and sunny due to its Continental Polar air origin from the North Pole similar to the very cold March 1962:-

Find me a weather station within 100 miles of Bicester that has a colder over night start to March in the last 100 years.

I bet you can't list more then 5 years.

If it's not unusual find me 25 years when we have had colder nights at the start of March and Ill eat humble pie.

Ps a 'one off night' is not providing the answer

pps 6 weeks ago it was January and ...

I read the thread and saw no moaning from anyone - except yourself. If you're going to disagree with what's being said, at least spare us the straw man rhetoric.

I would say the low maxima are unusual but they don't strike me as "incredible". If we're still recording such maxima towards the end of the month, then that would be truly exceptional.

Considerably milder here today, currently 9C at Manchester Airport after a surprising low of -7C this morning. Quite an impressive diurnal range really.
