March 2017 Weather

An exceptionally mild month with average temperatures 2.0 C above the long term average, the monthly mean of 8.4 C making this the warmest ever March on our records (dating back to 2004). As a result wintry weather was almost non-existent, at least down here on the Holderness lowlands of East Yorkshire, with no snow or even sleet at any point during the month’s duration. Even frost was rare, just a single air frost lasting no more than four hours being recorded, and with the April like temperatures and plenty of sunshine this made for a very early spring this year with many trees in leaf by month’s end.

Sunshine totals were above average with the sunshine pretty much well distributed throughout the month with no particularly dull periods of weather, though four days would see no sunshine whatsoever. However these days were very much the exception and for the most part the weather was bright and clement for most of March, only the lamb showing up this year with no sign of the metaphorical lion.

Finally rainfall was slightly below average, 91% of the long term average being recorded by month’s end, with just 10 days seeing rainfall in excess of 1 mm. Being the first month of spring thunder can often be expected to be recorded in March, but this year March failed to blow his horn (hopefully not a portent of a poor harvest), though hail was recorded on the 21st, a heavy shower around midday creating a short-lived dusting of hailstones. All in all a mostly settled but exceptionally mild start to the spring.

1.0 C to 8.3 C / 1.8 mm / 4.0 hours / SW 3-4
A bright start to the meterological spring with alternating sunny periods and cloudier spells, the sunshine feeling pleasant enough out of the breeze. A few showers would sweep through in the afternoon however, a few of which were quite heavy (5.0 mm/h), but these would die out again by the end of the afternoon. Clear spells in the evening and at first overnight, this allowing temperatures to dip low enough for a ground frost, but cloud would increase later with some outbreaks of rain arriving shortly before dawn.

2nd March 2017, Thursday
0.6 C to 9.2 C / 0.0 mm / 5.2 hours / W 4-5
After early rain cleared away, conditions would quickly brighten up with some good spells of sunshine developing during the remainder of the day. However a brisk breeze meant it felt quite cool, especially out in the open. Variable amounts of cloud in the evening and overnight.

3rd March 2017, Friday
3.4 C to 7.5 C / 7.9 mm / 0.0 hours / SE 3
A cloudy and dull day with outbreaks of persistent rain arriving in the afternoon, this rain continuing for the rest of the day and into the evening.

4th March 2017, Saturday
5.2 C to 11.2 C / 0.0 mm / 3.3 hours / S 3
A grim and dreek start to the day with outbreaks of early rain and murk for much of the morning, visibility being particularly poor up on the Wolds, but things would quickly improve by midday with sunny spells developing in the afternoon, feeling pleasantly warm in the sunshine. A day very much of two halves. Clear spells in the evening and overnight but remaining frost-free.

5th March 2017, Sunday
3.9 C to 10.0 C / 4.0 mm / 3.1 hours / NW 4
A fine morning for the most part with some good spells of early spring sunshine, though cloud would increase as the morning wore on. Indeed by the afternoon outbreaks of rain would arrive from the SE with the rest of the day seeing further spells of rain, this rain continuing into the evening and the night, albeit becoming more intermittent and lighter. Clearing by midnight with even some breaks and clear spells developing latterly.

6th March 2017, Monday
2.9 C to 9.6 C / trace / 1.4 hours / W 3-4
A mostly cloudy morning, though not without some clearer and brighter spells, especially during mid-morning, though during the middle of the day conditions would become more generally cloudy, the cloud thick enough to produce the odd spot of rain from time to time. Becoming brighter again by mid-afternoon with some sunny spells for the rest of the day, though again cloud would increase in the evening, this bringing a short period of rain around 9 pm. Becoming dry thereafter with variable amounts of cloud for the rest of the night, temperatures dipping down to 2.7 C by dawn.

7th March 2017, Tuesday
2.7 C to 10.4 C / 6.7 mm / 8.3 hours / S 3-4
A beautiful spring-like day throughout with an abundance of sunshine pretty much from dawn to dusk, the sunshine feeling warm and pleasant in the shelter of the walled garden.

9th March 2017, Thursday
4.4 C to 12.9 C / 0.0 mm / 9.0 hours / NW 4-5 (6-7)
A mild and sunny day for the most part, though the main feature of the weather, especially during the morning, was the strength of the north-westerly wind with gusts of up to 44 knots for a time in late morning. However in the afternoon this wind would quickly ease to leave a pleasant and sunny end to the day. Becoming cloudy overnight but remaining dry.

10th March 2017, Friday
3.7 C to 11.6 C / 0.3 mm / 0.1 hours / S 2

11th March 2017, Saturday
7.8 C to 12.6 C / 0.7 mm / 0.0 hours / SE 1

13th March 2017, Monday
2.9 C to 12.8 C / 0.0 mm / 5.0 hours / W 4-5
A fine start to the morning although feeling much colder than of late, but in the abundant spring sunshine things would soon warm up as the morning progressed. However in the afternoon things would cloud over, the cloud accompanied by a moderate to fresh westerly breeze which made it feel quite cool, especially out in the open. Becoming clearer again in the evening and overnight, though a variable layer of thin cloud veiled the near full moon and the stars, whilst the breeze would also pick up again towards the end of the night.

14th March 2017, Tuesday
5.7 C to 15.0 C / 0.0 mm / 4.2 hours / W 4-5

Becoming breezy for a time as well but soon easing again. Variable amounts of cloud overnight with some clearer spells around midnight, but becoming grey and overcast by the end of the night. Cooler.

17th March 2017, Friday
3.5 C to 12.1 C / 0.3 mm / 0.0 hours / W 5 (6)
A grey and dull start to the day with a brisk and chilly breeze sweeping across the fields, and it would remain mostly cloudy and cool (at least compared to recently) throughout the day, the cloud thick enough to produce a period of rain in the afternoon. Becoming drier but remaining cloudy overnight, though the main feature of the weather during the night would be the strong and gusty wind with several gusts in excess of gale force being recorded after midnight.

18th March 2017, Saturday
6.6 C to 14.4 C / 1.3 mm / 0.3 hours / W 4-5

20th March 2017, Monday
7.8 C to 11.3 C / 1.8 mm / 3.0 hours / W 4-5
A mostly cloudy morning with periods of rain & drizzle at times, the rain becoming heavier and more persistent towards the end of the morning and around midday.

21st March 2017, Tuesday
2.6 C to 9.7 C / 3.5 mm / 7.9 hours / W 5
A blustery day with a fresh westerly breeze, the brisk breeze making it feel quite chilly, but despite this it was a largely fine day with good spells of sunshine.

4.0 C to 9.0 C / 4.5 mm / 0.1 hours / SE 4-5

2.8 C to 10.8 C / 0.0 mm / 8.5 hours / NE 4
A damp start with some early outbreaks of rain, but these would soon clear with conditions brightening as the morning wore on.

Remaining mostly clear in the evening and overnight with temperatures dipping low enough for a touch of ground frost.

24th March 2017, Friday
1.0 C to 11.9 C / 0.0 mm / 11.4 hours / E 3-4
A clear and chilly start with a touch of ground frost in the usual prone spots, but in the abundant morning sunshine things would quickly warm up with a fine spring day following with wall to wall sunshine and largely clear blue skies throughout.

27th March 2017, Monday
2.6 C to 9.5 C / 0.0 mm / 0.0 hours / E 2
A dull and overcast morning, a bit of a shock to the system after all the recent fine weather, but it was relatively mild with no frost. Remaining cloudy throughout the rest of the day, though it did become somewhat brighter for a time around 3 pm, but all in all it was a pretty grey and nondescript sort of spring day. Little change in the evening and overnight, though low cloud would form over the Wolds towards the end of the night with general murk down here on the lowlands.

31st March 2017, Friday
12.5 C to 17.8 C / trace / 5.1 hours / S 3-4
A muggy and grey start to the day, the cloud thick enough to produce some light rain for a time in mid-morning, though things would begin to brighten up by 11 am with a fine afternoon following with good spells of sunshine and temperatures again climbing up towards 18 C.
