Weather Commentary

Commentary

January 2009 January was the coldest full month, on average, that I've recorded, and also produced the coldest temperature at -7.5°C. The cold was mainly around the first two weeks, and included one "ice day" on January 10th, when the temperature remained below zero through the day, only reaching -1°C maximum. It also started with a drought, when we had no precipitation (of > 1 mm) for 22 days. We didn't even have rain then, since what fell was snow, which gave us quite a good covering on January 5th. The second half of the month was generally closer to average, both for rainfall and temperature, although it seemed rather dull in general. The early part of the month was also distinguished by continuing high pressure, while the second half was quite the reverse, with low and very low pressure the norm. On the 23rd, the pressure dropped to an exceptional low of 964 mBar, only 1 mBar above my lowest recorded pressure.
February 2009 Another classic month of 2 halves. The early part of the month was very cold, with the temperature maxima and minima below the long term average on every single day. It was also notable for precipitation - there were 9 days with > 0.3 mm precipitation in the first half of the month, but none in the second. The second half of the month was also very warm, with every single day recording a maximum and minimum above the long term average. February 2nd was notable for a heavy snowfall - widely reported as the heaviest in Southern England for 18 years, succeeding in closing many airports, including Heathrow. This was not good for my skiing holiday which began the next day! So, on average, February looked quite normal. In practice, it was quite unusual - very wintery to start and quite spring-like to finish.
March 2009 March started by continuing the dry spell that had started on February 14th. It eventually rained on March 4th - a dry spell of 18 days and a "mini-drought". There was further rain on the 8th and 10th, but then another dry spell until the 23rd. As might be expected, the dry spells were accompanied by high pressure. The middle of the month was generally warm and spring-like, although the nights were cold and frosty.
April 2009 A month of hot, dry days and cooler nights. There was only measurable rain on 2 occasions - the 16th/17th and the 27th, and it was the 3rd driest month I've recorded. The rain on the 16th broke a rainless spell of 19 days - another mini-drought. Every day's maximum temperature was higher than the long-term average. There was also lots of sun, and the solar panel was working flat out in the latter part of the month, producing all the daily hot water.
May 2009 Another warm, sunny month. Daily maximum was above the average maximum on every day, and the garden was looking for more rain. To be honest, there's not much more to be said, so I won't.
June 2009 June started cool and rather damp. Then it started to get warmer, and mid-month delivered a substantial storm which crossed the country and dropped 22 mm of rain on Bealings and quite a lot more in other local areas. In a month of 43 mm rainfall, that was over 50% of the month's rain in about 3 hours. From then it was pretty much sunny, hot (sometimes very hot) and dry - only 1 mm of rain fell in the second half of the month. There was many headlines of "Heat wave" and the standard newspaper photo was of people licking ice creams. Despite that, on average it was almost the coolest June I've recorded. We do need more rain, though.
July 2009 Ask and ye shall receive. July 2009 was notable for considerable rainfall, much of it in heavy localised showers - for example, on the 24th of the month, 10 mm of rain fell in 10 minutes. Later in the month we had a brief burst of hail. In total, we had almost twice the long-term average rainfall, and had rain of > 1mm on 12 days. Apart from that, it was a quite pleasant month. There were no extremely hot days and when it wasn't raining it was generally bright or sunny.
August 2009 In contrast, August was hot and dry. The long-term average maximum was exceeded on almost every day, and it was the hottest average temperature I've recorded for an August, and only beaten by the exceedingly hot July 2006. Rain fell on only 4 days, most of it a pretty desultory mm or so, and so the 8.9 mm recorded makes it the driest August I've recorded, and the 3rd driest month ever. Our 1000-or-so litres of rainwater in the butts ran out and I had to resort to turning off the pump on the pond to save water for the fish to live in. No doubt the local seaside hoteliers were happy, though. And the farmers doing the harvest.
September 2009 September in Great Bealings was most notable for being very dry - the driest I've recorded. Following a dry August, we are now very short of water - the 2 months brought use about 80 mm less rain than normal. It only rained on 2 days, and by the end of the month we had entered a mini-drought - no rain for 15 days. Apart from that, it was generally warm during the day (with the highest September temperature I've recorded of 28.8°C on the 8th), sunny and with average temperatures at night. Pressure was high on average.
October 2009 October continued the dry theme of the previous two months. It began with a drought, and over half of the recorded monthly rain fell on a single day - the 21st. The second half of the month was notably warm during the day, owing to a southerly wind. There were a few foggy nights, but no air frosts at all.
November 2009 November was wet, warm and windy. Whilst we had higher than average rainfall, it was nothing compared to the rain that fell in Cumbria - over 300 mm in one day (over 6 months' worth for us), resulting in flooding in Cockermouth and main road bridges being washed away in Workington. The unusual feature here was the preponderance of low pressure - the average for the month was only 1000 mBar - 14 mBar below what I normally record. It was also unusual in being a November without air frost - we would normally expect about 5 air frost in a normal November.
December 2009 December was cold and wet. I think it was the first time we've had snow in December since I've been recording the weather - it fell on the 17th/18th and was still on the ground for Christmas. Around that period it was exceptionally cold, with the 19th proving to be an ice day - when the temperature never got above freezing. The temperature at day-break on the 23rd was the lowest December temperature I've recorded (-7.5°C) and the joint lowest I've ever recorded. We had a further scattering of snow on the 31st, which made driving a little difficult. It was also the wettest December I've recorded.

It also marked the partial demise of my 3rd laptop - the hard drive failed on 6 December. Fortunately I noticed quite quickly and already had a standby. Using backups, I managed to get going again with the loss of only a couple of hours of data.
