The statistics from this local weather station are currently being uploaded to ‘Weather Underground’, a commercial world-wide weather service providing real time weather information for almost anywhere!
The data from any weather station will reflect its own topography, altitude and local environment. Figures will vary somewhat from other reporting weather stations even close by. Typically each station locality possesses its own micro-climate. Over a year (or even longer) these variations are ironed out somewhat and a picture of the local climate emerges.

MONTHLY SUMMARY NOTES OF WEATHER OBSERVATIONS IN ANSTY
December 2020. Cool Beginning; Mild mid-month; Cold ending; Above average Rainfall!
December’s weather patterns carved the month up into 3 neat packages: the first third was relatively cool with a couple of sharp night-time frosts but with one very wet day on the 5th. The middle third was often humid, mild or very mild with many days when rain fell on and off. The last third saw the arrival of cold polar maritime air washing over all of us – firstly on the eastern flank of a very short-lived anticyclone and then courtesy of a deep depression named Bella which sucked in more cold air from the north and even gave us a few flakes of snow in the rain showers. In years gone by cold polar maritime winds from the Arctic would have brought snow and ice to all of the country even in December. Some places did get snow but it didn’t stay for long – only on the higher ground.
What was exceptional about this month is that air pressure for almost the entire month was decidedly low – with huge depressions dominating the eastern Atlantic allowing a series of secondary depressions and attendant fronts to flick around the margins bringing showers or rain. Winds often welled up from the sub-tropical south pumping in very mild air. No wonder days were damp and humid. When depressions did manage to drive through into the North Sea and beyond, then cooler north or north westerlies flooded in.
On December 23rd a large deep depression (named storm Bella) move south with a steep pressure gradient on the western flank which allowed cold air from the Arctic to rush in and displace the mild, stagnant air and gave us a very windy night.
Overall the average monthly temperature was (yet again) well above the long term average (which by dint of the continuing succession of above average monthly temperatures over the past few years means that the long term average is also increasing!) This time the monthly average was 1.5 C above the ‘norm’ with the mean maximum temperature close to 2 C above the norm*.
December was also a wet month with 5.56 inches of rain (LT average 3.92 inches). Only 6 night frosts were recorded and 7 ‘bright’ or sunny days.
Will January buck the warming/wet trend or will it be freezing with days of snow? Wishful thinking more likely!
*Currently the average monthly temperatures our weather station figures are compared against long term set of 30-year averages, covering the period 1981-2010.
Previous to these sets of figures, average monthly temperatures were compared to even earlier sets of 30 year averages for districts, regions and the UK, covering the periods 1961-1990, 1971-2000. The latest 30 year average is currently being constructed as a ‘norm’ baseline is 2011-2040 by which time the monthly average ‘norm’ will have risen even further! In fact the warming trend has gone on unabated for almost 60 years on an accelerating trend! The nearest sets of comparable climate figures are from Boscombe Down, in Wiltshire.
