January was statistically cooler and drier than normal. Temperatures switched from pleasantly mild to cold and frosty several times during the month, and most rainfall was in the second half of the month. 

Air frosts 2^nd-5^th, 10^th, 17^th-18^th, 23^rd-24^th, and 28^th-31^st.  Wettest days were 8.1mm on 16^th and 9.7mm on 29^th, with hardly any rain between 1^st and 15^th.  Quite windy at times on 27^th and 13^th, less so 8^th, 12^th and 26^th.

So quite a varied month overall. It felt pleasantly mild at times, but bitterly cold at others. No monthly records were broken, most parameters ranking midway in the 64 years of records held.

 6.0 mean max (C) 

14 raindays (>=0.2mm)

22 ground frosts
13 air frosts 

A very mild February, sharing the record for highest mean temp of 7.1C with 1998. Temperatures rose steadily throughout the month, peaking on 26^th. The only air frosts were in the first 5 days of the month.  Rainfall overall was normal for the month, but virtually all of it fell between 4^th and 10^th, after which it remained dry until 28^th.  The sunniest days were 14^th-16^th and 21^st-27^th, dullest were 5^th, 8^th and 28^th.

Growing and cultivating the soil was unseasonably pleasurable for the second half of the month.

Winter was statistically the 6^th mildest, but while Dec and Feb were much milder than normal, while Jan was slightly cooler.
Rainfall was normal overall, but varied, as Dec was very wet, Mar normal and Jan drier than usual.

March statistically has been a mild and wet month, although the first half was cool, wet, and windy at times with some fairly sunny days, while the second half pleasantly mild, very sunny, calmer and dry.
The mean temp of 8.0C was 1.5deg above normal, the 6^th highest equal in 64 years here. Consequently there were only 10 ground frosts (just 12 years have had fewer, many of these in the last decade), and no air frosts (only 3 years have now experienced this, in 1981, 2012 and this).
This was the 8^th wettest March (156% normal), beaten from 1979 to 1982, also 2013, 2016 and 2018. Moreover, this nearly all fell in the first half of the month.
No snow was seen here, although some fell a few miles away on higher ground. There was a brief hailstorm at midday on 17^th .
So a varied month, but finishing far more spring-like than it began!

A slightly milder and drier month than normal, although statistically unexciting.. Temperatures were lower up to 9^th, then remained above average for the rest of the month. Most rain fell 7^th, 8^th and 9^th, accounting for 36mm of the 49mm monthly total. Sunniest days were 11^th to 16^th, and 21^st to 23^rd, whle the dullest days were 8^th, 17^th-18^th and 29^th.  The windiest days were between 26^th and 31^st.  The warmer and drier middle part of the month from 11^th to 25^th necessitated plenty of extra watering for fruit and vegetable crops.

Fairly average temperatures for most of the month, but hot 22^nd to 26^th, peaking with 35.1C in the afternoon of 25^th.  This made the mean temperature of 18.2C the 9^th highest in 64 years.. The high max is a new July record, beating  2006/2015 and 2016.

Most of the month was dry, with only 21.1mm up to 29^th, then came rain with some  torrential downpours on 30^th, bringing the monthly total to 68.6mm. That single day ranks 11^th in 23376 days (64years) of records here.

There were thunderstorms from late on 23^rd into the early hours of 24^th, with just 3.4mm rain between 0130 and 0400. Temperatures on 23^rd had reached 32.3C.
Pressure showed rapid falls and rises, varying by over 2mb,  as these storms passed over.

Brightest days were 3^rd-5^th, 7^th, 15^th and 20^th-25^th. Dullest days were 6^th,19^th, 27^th-28^th. So statistically a warm and slightly wetter than usual, but this hides the detail.

August was statistically mild and wet, but again the variation through the month was significant. Much of the month saw typical mean temperatures, but it was warmer 1^st - 9^th and 22^nd -31^st, especially hot from 23^rd - 27^th.
Most of the rain fell in the first half of the month, while it remained dry 1^st-3^rd and 20^th-26^th. It was particularly windy 9^th-10^th , less so 15^th-16^th and 30^th-31^st.
While the highest pressure was around the median,  unseasonably low pressure when it came was in the lower quartile.
A good growing and harvesting month for fruit and vegetables.

A cool November, with mean temperature 1.1 deg below normal overall, only being mild from 1^st to 5^th and 23^rd to 27^th, resulting in 4 air frosts and 14 ground frosts.
It was a very wet month, raining nearly every day, 47mm most falling 13^th-14^th , 23.7mm on 9^th – 10^th, and 19mm 1^st – 2^nd.  This equals the record raindays we had in 2015 and amongst the highest recorded wet days and very wet days here.
