cold and snow lovers after late November and December's excesses,
however this January in many Winter's of old would be perceived as a
cold one, with air frosts on 17 nights, these severe at times, as low

February
2011, Llanwnnen, Lampeter
Very
mild, rainfall a little above average.
The
re-appearance of a very mild Winter month after several years
absence. Few frosts and no snow falling at all, only a very little
barely noticeable sleet on 2 days mid month. The most remarkable
statistic being the lack of below average maxima, with no day failing
to reach 7c.
Although
it rained on 24 days out of 28, much of this was light, and the total
was only a little above the average
1st
- 7th:
Mild, cloudy, unsettled and windy with gales at times. A couple of
slight frosts.
8th
: Quite a sharp frost, sunny morning, then cloudy and mild.
9th
– 12h:
Very mild and unsettled, light rain and drizzle at times with some
sunny spells.
13th
-16th:
Near normal temperatures, spell of rain and the odd spot of sleet.
Sunny intervals, touches of frost by night.
17th
- 26th:
Mild to very mild, rain at times, rather cloudy but some sunny
spells. What seemed like a localised foehn effect produced the
month's highest reading of 13.6c on the 19th.
Heavy rain late on the 25th
made this the wettest day with 21.6mm.
27th
/ 28th:
Mostly dry apart from a few showers 27th
, cooler with night frost, and a sunny final day.

March
2011
Very
dry and sunny, very warm spell late on. Plenty of frost.
A
very dry month with only about a quarter of the average March
rainfall. Overall rather mild, but this being made up of contrasting
very mild maxima with cold nights, and whilst virtually no maxima
were below average there were 14 air frosts, quite a high figure for
March. No lying snow again, so none since early January now. Mean
temperature a touch below that of February which was a very mild
month.
1st
- 8th:
Hard frosts by night, mostly sunny days. Maxima
slightly above average, but very cold nights as low as -6.9c 0n the
8th,
the lowest in March for quite a time. Minima averaged -4c in this
period.
9th
-13th
: Light rain or drizzle at times, near average temperatures and
breezy.
14th
– 21st
: Mostly dry and mild with sunny spells at times. Hard frost 19th
(-5c).
22nd
– 28th:
Very warm and mostly sunny, with some slight overnight frosts.
Unseasonably high maxima for early Spring, peaking at 19c on the
24th,
including a run of 5 days topping 60f (15.6c), which is virtually
unprecedented.
29th
- 31st
: Unsettled,
breezy with rain at times, mild. Final night the mildest, minimum
8.5c.

April
2011, Lampeter, west Wales
Exceptionally
warm and sunny. Very dry
As
with the CET zone, west Wales has almost certainly had its warmest
April on record, with, incredibly, mean maxima at early June levels!
The month was characterized by dry, sunny and warm to very warm
conditions and a deficit of cold, wet weather. Seven days exceeded
21c, itself quite an achievement as early as April, while just one
day failed to reach the average. Few frosts and just the single air
frost. Most of the rainfall total of 29mm fell in the first 5 days,
with only 5mm thereafter. I would guess that it was also the sunniest
ever April.
1st
-5th:
Near normal temperatures with rain and showers at times. Quite a
spectacular, though brief thunderstorm in the early hours of the 2nd.
6th
-10th:
Warm to very warm and mostly sunny.
11th
-13th
: A little rain and times, much cooler, only reaching 9c on the 13th.
14th
- 22nd
: Dry, soon became warm to very warm again. Sunny periods, although a
few cloudier days too. Temperatures peaked at around 24c on both
21st
and 22nd
(Good Friday), and were just short of the remarkable values of April
2007. Light showers on the evening of the 22nd.
23rd
- 30th
:
Mostly warm and dry with sunny periods, although much cooler than
Good Friday. First air frost on 28th,
only slight. A very warm but quite windy final day- fittingly for
this truly exceptional month.

July
2011, Llanwnnen, Lampeter
Near
average rainfall and temperatures; driest since 2006
Overall
a fairly 'typical' July, if such a thing exists! Both overall
temperatures and total rainfall being very close to average. In finer
detail, the month was often unsettled for the first 22 days, then
mostly dry; a high frequency of cool nights (8 getting lower than
8c), and a lack of heat throughout the month with 25c not being
reached. A high incidence of fog -7 days- but this perhaps more of a
reflection of the fact that I now have a webcam and can view
snapshots of pre- dawn and early morning mist and fogs, whereas in
previous Summers, my slumbers meant I remained blissfully unaware of
them!
1st
– 4th:
A warm, sunny start to the month but with very chilly nights in the
3-6c range, and close to ground frosts.
5th
– 10th:
Unsettled with rain or showers, some heavy, also sunny spells. Rather
windy with near average temperatures.
11th
– 14th:
Mostly dry and rather warm, sunny at times. Thundery showers passed
close by on the 12th
but we escaped with just trace rainfall. A very cool mid July night,
minimum 3.8c on the 14th.
15th-
22nd:
Very unsettled, often cool and breezy. Generally cloudy with spells
of rain and showers, these very heavy at times. 21.6mm on the 21st
made it the wettest day since February (this however showing the
dryness of 2011 to date and lack of really wet days).
23rd-27th
: Dry and became warm. A mix of cloudy and sunny periods with the
north-west flow about the high to the west. Plenty of early morning
mist and fog, some nights being very cool once more.
28th
– 31st:
A mostly cloudy, rather warm and humid end to the month. Some bright
spells but also a little light rain or drizzle at times.

September
2011 Weather at Lampeter, Wales
Generally
unsettled: rather warm, thanks to an exceptionally warm end; average
rainfall
A
rather mundane month until the last few days heatwave, and apart from
the ex-Katia gales on the 12th.
It was a measure of the coolness of Summer 2011 that September ended
up with a similar mean temperature to July and August and indeed with
warmer nights!
1st
/ 2nd:
Dry and warm first couple of days, and sunny on the 1st.
3rd
– 13th:
Very unsettled and windy with showers or longer spells of rain, these
heavy at times. The former hurricane Katia gave gale force winds on
the 12th.
Temperatures close to average by day but very mild by night, a high
minimum of 16.7c on the 10th.
14th
/ 15th:
A ridge gave a brief dry interlude with sunny spells, and again
average temperatures of around 18c.
16th
- 25th
Unsettled
once more, with rain or showers at times, temperatures close to
average, not much sunshine, and windy at times.
26th
: Foggy start, then dry with some sunshine.
27th
– 30th:
An exceptionally warm end to September, and warmer than most of the
actual Summer.
The
last 3 days were incredibly warm for the very end of this Autumn
month, each day exceeding 25c, a level that July and August did not
reach once- and with warm nights too (above 14c). Needless to say
dry, and mostly sunny, although breezy.

November
2011 at Lampeter in west Wales
Exceptionally
mild, below average rainfall
Very
little in the way of cold this month, and although unsettled at
times, Ceredigion was spared the worst of the rain.
1st
– 4th:
A
deep low close to Ireland made for a very mild unsettled start to the
month with rain or showers, heavy at times.
5th-
7th:
Cooler, dry with some sunshine and overnight frost and fog. Quite a
severe frost on the 7th
with a low of -5.5c which put paid to many of the late flowers and
out of season budding. A rather cold maximum of just 6.8c on the 7th.
8th-
11th:
Unsettled and very mild. Low pressure over the Atlantic brought up
more Tropical Maritime air from the south. Rain at times, some heavy.
It was often cloudy, although with a sunny interlude on the 10th.
12th
and 13th:
Exceptionally mild and dry with plenty of sunshine. 17c on the latter
was the highest this late in Autumn for several decades.
14th-
30th:
Mild to very mild and mixed. Sunny spells and also some rain at
times. Ground frost occasionally by night and a slight air frost on
the 23rd.
The final week of the month was often windy with gale force gusts at
times. The 11.6c minimum 29th
in stark contrast to the run of sub -10c nights we were in this time
last year! Still some budding and flowering.
