December
Six
days of records for this month were lost because of problems with
the electronic thermometer that I use. December turned out
to be the coldest month of the year, average temperatures were only
39.3°F - three degrees below
the seasonal average and 9 out of the 25 days recorded were frost
ones, when the average for December is 6.9 days. The 10th
and 11th were 2 of only three days this year where the average temperature
was below freezing. But it was the 12th that saw the lowest
minimum temperature of 28°F. A spell of prolongued high
pressure meant that rainfall was well below average with the 13th
seeing the only significant rainfall of the month.
November
Temperature
wise November was about a degree below average, but it was a very
wet month with 3.32 inches of rain, only exceeded by May. Highest
temperature was 56.7°F on the
16th, with a low of 28.2°F on the 23rd.
October
A
month of contrasts saw many days with above average temperature
at the beginning of the month, replaced by much colder weather at
the end. The average temperature for the last 3 days was below
40 degrees, well below the seasonal average of 52.9°F.
The temperature fell below freezing on 29 October (30.6°F),
an event that on average only happens in October once every three
years. In contrast the highest temperature was 63.3°F
on the 7th. Rainfall at 1.96 inches was below the seasonal
average of 2.42 inches, the very wet evening of the 30th saw 0.64
inches fall within a few hours.
September
September
was a cool month with the average temperature of 56.5 degrees F
almost 3 degrees below the long term average. There were 4
warm days on 8-11 September, with temperatures peaking on 9 September
at 71.4°F. Rainfall was almost
exactly on seasonal average.
August
After
recent years with scorching hot weather, an average August came
as quite a surprise to many. The historical average for August
is 64.2°F, and this year the
August average was just a shade below at 63.7°F. The hottest
day was the 6th at 79°F, with the coldest being the 24th, where
the temperature fell to just 51.1°F. There was nothing
average about the rainfall though with 2.51 inches falling, compared
with a seasonal average of 1.86 inches. Apart from being the
hottest day, the 6th was also the wettest with 0.72 inches of rain
falling. Most rain fell in the first half of the month.
July
Quite
a month of contrasts. The month began fairly cool with heavy
rain on the 7th (0.92 in) and the 9th (0.56 in), these two days
alone accounting for the average rainfall for the month. The
evening temparatures on the 12th and 13th fell below 50 degrees
which is unusual, the 48.7°F
on the 13th was the lowest of the month. The latter half of
the month was dry and
and the average temperature on every day from the 19th exceeded
the seasonal average. Temperatures peaked on the 31st at 83.3°F.
June
Generally
a very settled month, with air pressure continually between 1010
and 1022 mb. Temperatures were just above the seasonal average
of 60.2°F with a peak of 76.1°F
on the 10th. The middle of the month saw some chilly night
temperatures, falling to lows of 46.6°F on the 14th and 16th.
Overall a drier month than average with the only significant
rain of 0.40 inches falling on the 12th
May
It
looked like May was going to be a very dry month with rainfall well
below average..... until the 25th. Over the next 4 days nearly
3 inches of rain fell which is almost double the seasonal average
for the whole month. The 26th was the wettest day of the year
by far with 1.61 inches of rain falling. In spite of this,
the average temperature of 57°F
was over 2 degrees higher than the May
average. The temperature exceeded 70 degrees every day between
8-13 May, with the month's high of 79.2°F
occurring on the 10th. The evening temperature only dropped
below 40 degrees on the 19th and 20th, the 19th being the coldest
day with a minimum of 38.3°F. Air pressure was remarkably
consistent throughout the month, only varying between 1008 and 1021
mb.
April
A
very average month with temperatures a little above seasonal average
at 49.6°F (9.8°C). The
warmest day was the 22nd where the garden thermometer recorded 74.1°F
(23.4°C), however as this was much higher than the met office
figure for the day, it caused me to move the thermometer to somewhere
that would definitely be in the shade all day. However the
temperature fell below freezing on 5 consecutive days from 6-10
April with a low of 27.5°F (-2.5°C), when the long term
average for April is only such day. Rainfall was a little
below average with the wettest two days being the 29th and 30th
at about 0.3 inches each.
March
March
saw the first snow of the year, a few flakes on the 22nd was followed
by a prolonged shower on Easter Sunday, the 23rd and some snow on
the 24th. However
it did not settle for long.
Although there was an above
average 6 days of below freezing temperatures, overall the month
was close to the long term average. The warmest day was the
15th (65.8°F (18.8°C)),
the coldest was the 5th (26.8°F (-2.9°C))
There was above average rain.
The heaviest rain of the year
occurred on March 10th, when 0.99 inch fell (1 inch of rain is equivalent
to 100 tons of water per acre of land).
February
Feburary
was quite a contrast to January, as it was much drier and colder,
but only a shade below the long term average.
The only significant rain fell on 5th Feburary (0.31 in). The
number of days where the temperature
fell below freezing was above average at 10, with 9 of the 11 nights
between 10-21 February were below freezing, coinciding with a long period of high pressure.
The 17th was the coldest day of the year so far with a minimum
of 21.4°F (-5.9°C), the average temperature that day was
the only one this year to be below freezing. The end of the month
saw warmer weather and some rain (24,25,27&29 Feb). The
hottest day was the 24th (61°F (16°C)
January
A
very unseasonably warm month. The temperature only dropped
below freezing on 3 days (2nd, 3rd and 28th). The 20th was
very warm for the time of year with a top temperature of 61°F
(16°C). Coldest day was the 28th with 30.4°F (-1°C).
Average temperature over the month was 44.5°F (7°C).
It was quite a rainy month with 2.68 inches (68mm) of rain.
The wettest days were the 15th (0.84 inch) and the 11th (0.53
inch).
Average temperature is the average
of the maximum and minimum for that day. The long term average
is the Met
Office figures for Greenwich 1971-2000.
