Weather Commentary

Commentary

January 2012 The main thing to remark about January 2012 was that it was the month I replaced my Oregon weather station with a Davis one. The new one has got better barometric resolution, an improved rain gauge and much better solar shielding - it also has a solar-powered fan to keep the temperature stable if the sun hits the solar shield. I also moved the new anemometer 4' higher, so it is now well clear of the roofline - recorded windspeeds are therefore considerably higher than they were with the old system. The humidity meter on the Oregon system was also under-reading. As a result, most of the records will not be strictly comparable. I also upgraded my weather recording software. Unfortunately, the software supplied by Davis to interface to my PC was not reliable, causing my PC to crash and as a result, some of the data from January was lost.

Anyway - that's that out of the way. As for the weather - not much out of the ordinary - rather warmer than normal.
February 2012 The start of the month was exceptionally cold, with a decent fall of snow - about 6" - on the night of the 4th/5th. The 4th was an "ice day" - when the temperature never got above freezing. The maximum temperature that day was -0.7°C. Once the mid-month passed, the temperatures got very much higher and we had a number of spring-like days. Interesting to get a month with both a record high and low temperature for February. It was (apart from the snow) very dry, continuing the drought-creating conditions we've been experiencing of late. It was also dominated by high pressure - 1029 mBar on average. Some months we don't even get pressure that high, let alone average it!
March 2012 March was, in general, warm and dry (although the rainfall stats don't show this). Despite overall rainfall being just above average, most of it fell in 5 days of fairly heavy rain, with large gaps in between. As I type this, there's been no rain for 13 days and we're headed for another mini-drought. The last half of the month felt very spring like- with lots of sun and temperatures during the day more like May. The blossom is out and the birds are singing. Let's just hope the frost expected later doesn't do too much harm.
April 2012 Cold and wet - that's how it felt, anyway. In comparison to met office data, it was actually about average temperature, although it was the coldest April I've ever recorded. It produced about twice the expected rainfall, although again it was no where near the wettest month I've ever recorded - it's only eighth in my order of "merit". It was the wettest April. It actually started comparatively dry - on 2nd April we'd had no rain for 15 days (a mini-drought). It was the second half of the month that was really wet - 50 mm of rain in 10 days.
May 2012 A month of two halves, Brian. The start was cold and wet, and the end warm and dry. We had around 50 mm of rain in the first half of the month, and the temperature almost never reached the average max. Then the rain stopped, and we had a mini-drought of 15 days with no rain, and the maximum daily temperature always exceeded the long-term average. The second half of the month felt much more like July than May.
June 2012 Generally cold and wet. The early part of the month was particularly cold and overall the average was looking to be no better than May until we had a warm and muggy spell at the end of the month. It was a similar story with rain - lots of rain and rainy days to start with. However, we missed the very heavy rain showers that many other parts of the country had.
July 2012 In an echo of the words for June - generally cold and wet. It was just the coldest July I've recorded and, although we had about twice our normal rainfall, it wasn't quite the wettest I've recorded - that honour falls to 2004, with 105 mm. The 8th was an exceptionally wet day, with 38 mm of rain falling. As it turned out, most of it was while we were asleep, so we weren't really aware of it. The cat stayed in, though.
August 2012 My main recollection of August was that it was very dry - unusually so, given that the rest of the country appeared to have been deluged in rain. We'll have to wait for the Met office anomaly charts to see the real difference. It's also being said that this has been the wettest summer (Jun-Aug) for 100 years. Not here it hasn't - it's not been the wettest summer since I've had a weather station. My measurements show 181 mm of rain this summer. In comparison, we have 2011 (191 mm); 2010 (185 mm); 2007 (241 mm) and 2004 (273 mm). We also had a "mini-drought", with no signiifcant rain for 17 days ending on 25 August. Apart from that - generally pleasant; a bit hot mid-month and a bit cold at the end.
September 2012 Started dry, ended wet. The end of the month was cold, too. In terms of numbers, the equal coldest September I've recorded. In terms of turning the heating on - 20th September, about 20 days earlier than last year.
October 2012 Felt cold and wet. It's the wettest October I've recorded, and the rain fell fairly consistently during the month. It was generally cool (though frost free) and it appears that it's only some warm nights in the middle of the month that prevented it from being the coldest October I've recorded. A period of high pressure around the 23rd brought low winds and mist/fog.
November 2012 It felt a rather wet and cold month, but statistically it was neither - about average rainfall and temperature. The rainfall wasn't average in the rest of the country, though. Significant falls during the autumn have left most of the country waterlogged, and this resulted in significant flooding in the West and North East. Sometimes living in a somewhat arid region does have its benefits. The month ended with a cold snap which brought frost and freezing fingers on the motorbike.
December 2012 From the end of the month, it's easy to forget that December started cold and frosty. I was glad the motorbike was being serviced, "forcing" me to take the car to college. However, after mid-month it got noticeably warmer, with minimum overnight temperatures often higher then the long-term maximum for the month. That aside, it was generally wet and miserable, with many parts of the country suffering continuing flooding.
2012 An interesting year for the new weather station. It looks like it's considerably more accurate at recording maximum temperature (better shielding) and humidity. It is clearly better at measuring small amounts of rainfall - although whether it's more accurate is always difficult to tell. The wind gauge also records wind more accurately, being a better device and mounted higher.
