December 2014

Comparatively speaking, December was a dry month with the rainfall well below the 34 year average. Most of the rain fell on just 3 days although there was some precipitation on many of the days. Pressure was high and temperatures were something of a rollercoaster. There were days when the temperatures were in double figures and very little difference over the 24 hour period (22nd for example when the variation was from 12.3 to 10.0C) and others when the figures were far more what one would expect for December with overnight frosts and daytime not getting above 3C. The winter has started without much of a sting; long may it continue.

November 2014

November was wet and mild; the ground and the amount of water sitting on the surface is evidence enough. There were few frosts and these affected mostly the car windscreens with the thermometer not actually dipping to minus. The first few days were bright but the rest of the month was cloudy, dull and really rather uninspiring. After a period like that, it is a pleasant surprise to have sunshine and feel ones spirits lift. How people much further north cope with months of not even seeing the sun is remarkable. Compared with 2013, this November was wetter, warmer, less frosty just and very similar with regards to cloud cover.

October 2014

Warm, wet, frost free, not that windy and a record maximum temperature on Halloween, made for an October that has taken us well into the autumn without really bad weather and makes spring that bit closer. Hyde Heath didnt quite make 20C on the 31st but at 19.2C it was warm  and some 8-10 above the norm. The seasons do seem to be changing; when I was young(er) the big thing for Bonfire night was to collect sacks of leaves for the base as most of the trees were pretty bare; look at them now.

September 2014

September was warm, dry and had quite a lot of sun. Most of the rain fell on just one day, the 19th, with 33.4 of the total of 39.9mm. We were in Kos for the last fortnight and from my daughters observations it looks as if the weather here was nearly as good as it was in the Greek islands! September was a better month than August; much drier and very similar temperatures. Looking back at September 2013, this last moth was similar temperature wise but much drier with 7 days of rain compared with 15 days in 2013. Over the years, September2014 was drier but the pattern has been one of considerable variation.

August 2014

Compared with last year August was a deal wetter. In 2013 there was below average rainfall and followed 2 previous months of low rainfall. The temperatures this year pleasant but down on 2013; then the maximum temperature only dropped below 20C on one day-the 31st. This year 8 days were below that figure with the 25th seeing a rather miserable 16.8C with rain all day.

 When it rained we were subjected to some heavy downpours with 3 days each having over 12mm ( inch in old money) and accounting for 50 out of the 84 mm total. So far September has been dry but the mornings have been getting cooler. A good year for the harvest; most is in and a good year for apples, sloes, runner beans and tomatoes---from my perspective anyway.

July 2014

July was another dry and very warm month. It started with rain on many days but the last two weeks were almost without any rain and consistently warm (even hot!). It is often the case in the UK that hot prolonged weather breaks up with thunderstorms; we havent had them yet (6th August). Nearly a third of the rainfall was on just one night when indeed there was a thunderstorm but that was the 17th before the prolonged hot weather set in. We did not quite make 30C BUT IT WAS CLOSE.

June 2014 

After all the rain in May, June was a much drier month. Statistically this should not have been a surprise as in the last 34 years, twice as many June figures have been below average as above it. The rain we did have most almost all as showers with the one on the last day being particularly heavy. The first 2 weeks were pleasantly warm with only 2 days with a maximum temperature below 20C, then very briefly the temperatures fell a little before recovering again in the latter part of the third week and throughout the last. Compared with 2013, June was just slightly warmer and less wet.

May 2014

May was a wet month with nearly twice the 34 year average rainfall. It was the second wettest May in 34 years, beaten only by 2007. There were some real contrasts through the month; a minimum temperature of 1.3C and a maximum of 26.4C although not on the same day! Compared with 2013 the average temperatures were higher and I suspect that this has been reflected in the growth rates of plants and grass. The high rainfall is reflected in the flow of the Misbourne; still going strongly and still running from Mobwells down. It is a great shame that Fete day was not that good but thankfully people still turned out and enjoyed themselves.

April 2014

April was the second dry month this year with rainfall below average. April is a variable month with the highest rainfall at 139mm back in 2000 and the driest, only 3.7mm, in 1984. Temperatures were variable with a high of 19.8C and a low of 2.1C with just about everything between. Frost was evident on the top of the car on just 2 mornings but the old saying neer cast a clout till May is out warns us that frosts are still possible this new month. As I write this the forecast is indeed for frosts early this Bank Holiday weekend. Still it did give the farmers a chance to catch up and the spring crops are now in and well up in some cases. The Misbourne is still full with water at Great Missenden but it is not running as quickly as it was.

March 2014


All change!! After 5 months of heavy rainfall, March turned out to be quite dry. Rainfall was well below average for the month, less than a third of the wettest March (111.5 mm 2001) and three times the driest (11.3 mm 2011). There can be little doubt that there is no pattern from year to year. It was also a mild month with temperatures often over 15C and, although there were ground frosts on7 mornings, there was just I day when the air temperature dropped below zero. It is clear though that ground water levels remain high with the Misbourne running from Mobwells. The dry spell allowed the farmers to cultivate and seed the ground left over the winter. Our aquifers are apparently replenished in the 6 months from October to March; this year they have had a good drink with virtually 50% more than the average but still below that really wet winter of 2000/1. Why then all the floods this winter? I offer no explanation!

February 2014

The Met Office announced that it was the wettest winter since records began-and that was before the end of February. Winter in rainfall terms is defined as the months of December to February. Hyde Heath did not buck the trend !

This is by far and away the wettest winter we have had in 33 years. The amount of rain was 443mm compared with an average of 215mm and the previous high in 1989/90 of 360mm. It has been wet but mild with no snow, very few frosts and higher than average maximum temperatures. Looking at trends and averages including this years figures is not that meaningful as extremes throw things out but it is going to be interesting to see how the figures carry on in the future.

February as a month was also very wet with nearly 3 times the average rainfall and temperatures significantly above last year. There were very few frosts and a lot of cloud and wind. We are fortunate not to suffer the flooding of other parts of the country; an advantage of living on the top of a hill but a glance at the Misbourne it ample evidence to show how even a small river can overflow and flood land. If we are very lucky maybe the planners for HS2 (sorry to use bad language) will conclude that a tunnel under the Misbourne will merely be a different bad for it to flow in and alter the route completely or even cancel the whole project.

Our farmers are now well behind as the land is so waterlogged that ploughing is not possible and the winter crops are potentially, even here, vulnerable to rotting in the ground. Will the Water Board dare to announce hosepipe bans this year ?

January 2014

January was the wettest January in the last 34 years but I suspect you already knew that. It was also the second wettest month in the last 34 years; the wettest being October 1987by a mere 0.3mm. Rainfall was nearly 3 times the 34 year average for the month. Although it was wet, it was also a mild month with no really hard frosts and some high maximum temperatures. Fortunately there was no snow unlike January last year. The wettest day was on the 31st when some 18.5 mm fell; this however was not a lot compared with the 6th of February but you will need to wait until that report to see what the downpour measured! There was rain on virtually every day in the month with cloud being predominant. 

The total rainfall for 2013 was 751.5mm, close to average  but as you will see from the graph, some wide variations from year to year.
