The month started off mild before a brief northerly incursion on the 8th which gave a dusting of snow and a hard frost. It then quickly turned milder again, with 17.4°C being recorded 2 days later. Mid-month saw a calmer spell with average temperatures before the wind turned to the east bringing misty and gloomy days and some cold nights. For a period of 10 days midmonth the minimum temperature did not rise above 4.6°C. The last part of the month saw the wind turn south-westerly bringing much milder air from the south, allowing the temperature to reach 19.4°C on the 29th.

To summerise, another mild April very much above the 1971-2000 average. However the difference here to past months is that the higher average temperature was brought about not by a high average minimum, but a high average maximum.

Hello everyone, thought I would stick this in of my views and records of April.

The beginning of April saw high pressure to the east of the UK bring mild South to South easterly winds to most of the Country. Indeed it was sunny and warm over many parts on the 2nd with 19c being recorded here in Burton.

However this mild / warm spell was short lived because by the 4th temperature started to fall as a deep area of low pressure started to move towards northern Scotland, this bringing cooler westerly winds and some rain to most parts.

By the 6th the low had deepened to around 990mb with its centre being just off northwest Scotland, this brought some typical April weather with cool strong showery west to north westerly winds across the country, bringing temperature tumbling down further, with maximums being in the range of 9c to 11c.

By the 8th a full Arctic blast had got under way, this brought some spectacular frequent heavy hail, sleet and snow showers to many parts of the UK. Temperature dropped even lower, max of only 6c here.

From the 10th to the 21st temperatures recovered to average levels over most of the country.

Northerly blocking became quite a feature during this period with areas of low pressure often tracking across central areas of the UK, this causing winds to blow from an easterly direction for some lengthy periods, some frost was recorded also during this period, plus some heavy rain at times too, which made this month the wettest so far this year. However when skies remained clear during daylight hours, warm sunshine made for very pleasant conditions, even though shade temperature were only around the average, the exception to this being the 25th which saw temperature climb to 16c or 17c over many parts, very nice indeed.

Finally the end of the saw month warm plumes of air moving up from the south over the UK, but with low pressure not far away, the air was a little unstable, but there was some very warm sunshine at times which sparked off some thundery activity especially over the south and the midlands.

Maximum daytime temperature on the 30th = 21.1c

Minimum overnight temperature on the 8th / 9th = -2c

Average Maximum = 13c

Average Minimum = 4.4c

Mean = 8.7c

Rainfall total = 41.3 mm

Air Frosts = 2

Ground frosts = 7

Very similar but we just managed above average rain

[Thundery wintry showers]

I thought it was a very ordinary month in Tyneside, and not particularly memorable, with a lot of cloud, the odd bit of sun and the odd bit of rain.

Overall, rainfall was above average due to a few excessively wet days (the 14th and 15th stick out), and sunshine was close to normal. As usual temperatures were above the long-term average but not excessively so.

The events that stick out for me are a classic April day of sunshine and showers on the 6th, and the first snow in April since 2001 occurring on the 8th. Indeed, the last time we had a more potent cold snap than 8 April 2005 was back in mid April 1999. Then there were some fine sunny days during the final third of the month, albeit mixed in with some days of sea fog.

The month's average "Good Weather Rating" from me came out at 54%, which isn't bad, but is nothing spectacular. I suspect that May could come out with a somewhat higher rating though!

Here are my stats from Westbury, Wiltshire from April 2005 (compared to April 2004)

Average max = 13.56c (13.3c)

Average min = 4.16c (5.3c)

Mean = 8.86c (9.3c)

Highest = 21c on 30th (24c)

Lowest = -4c on 9th and 15th (-1c)

Dry days = 13

Precipitation days = 17 (of which snow/sleet/hail = 5)

**Both figures the same as 2004

Rainfall = 78mm (no figure for 2004)

The major difference is that this April had a few hard frosts which brought the mean temp down by about half a degree on last year.
