3rd April 2019: Brrrrrr!

<![CDATA[

I have to go back to the 2nd February (7.2°C) too for a day colder than today. A maximum of only 9.2°C even with plenty of sunshine between the showers to ‘warm’ it up a little.

April days with the maximum temperature below 10°C are rare here but 2013 broke the mould with 6 days <10°C and the 1st & 4th had maximum temperatures of only 5.8°C & 5.3°C. That was an exceptional April in my recording history.

Brrrrr.

26th March – Exceptionally sunny

<![CDATA[

Our first day of unbroken sunshine from dawn until dimpsey, this month.

Excellent visibility with crystal clear deep blue skies all day that made for 11.96 hours of sunshine recorded. That is an exceptionally high 95% of the total possible and not likely to be beaten as hills to the east prevent the total getting any higher.

A maximum of 16.9°C also made it the warmest day so far this year beating 16.3°C on the 27th February.

Despite today’s sunshine, this month may well end up with below average sunshine due to the very cloudy first half of the month. The average for March for the last 13 years has been 141 hours. The total to date stands at 92.7 hours.

1st half of March 2019 – Windy, wet and not very sunny

<![CDATA[

No sun here today making it the first sunless day since the 16th February.

Breezy but with a maximum gust of only 31 mph, a much ‘calmer’ day than recently, and dry too.

Wind run (1st – 15th) at 2691 miles, some Marches record less than that for the entire month. Looking at the forecast for something settled next week, I suspect this month will not end up record-breakingly windy. That record goes to March 2008 with 4601 miles.

Nearly half-way though the month and it has been milder, wetter but much cloudier than average:

Mean maximum = 12.5°C
Mean minimum = 6.3°C
Mean = 9.4°C
Rain = 59 mm
Sunshine = 47 hours.

Cold Front – 12th March 2019

<![CDATA[

Windy then it poured down (top rate around 60 mm/hr) and the temperature dropped away as the wind veered from SSW to NW.

Time Temp mph   

10:00 10.5C 20 SSW
10:05 10.4C 10 WNW
10:10 10.2C 12 NW
10:15 8.7C  10 NW
10:20 7.6C  8  NW
10:25 7.1C  9  WNW
10:30 6.7C  9  NW

10:45 6.1C  11 NW
10:50 5.9C  15 NW
10:55 5.6C  10 NW

Temperature went down to 4.7C by 11:40 and it did feel raw for the time of day. Then the sun came out and things warmed up a little, though only to a maximum of 8.3C. First sub-10C afternoon maximum by quite a margin this month.

C-c-c-c-cold Night

<![CDATA[It didn't look like it was going to be that cold last night but in the end the wind died away and the temperature dropped to -5.2°C making it the coldest night since the 4th February 2012 and only the 2nd sub -5°C temperature I have recorded since the 26th December 2010.

And last night's temperature was not over snow (none here).

Still, the compensation was unbroken sunshine yesterday and with the sun reaching over 23°, it has a lot more oooomphh in it than just a week ago.

Counted 30 stars in the 'rectangle' of Orion last night.
