These are the figures for Chalk Kent.

Mean Maximum Temperature for 2011: 15.9C (LTA +1.1C)
Mean Minimum Temperature for 2011: 7.9C (LTA +0.7C)
Overall Mean Temperature for 2011: 11.9C (LTA +0.9C)

Highest Maximum Temperature in 2011: 32.6C
Lowest Maximum Temperature in 2011: 2.1C

Highest Minimum Temperature in 2011: 17.7C
Lowest Minimum Temperature in 2011: -3.7C

Annual Rainfall for 2011: 454.0mm (81% LTA)
Days of Airfrost: 15 (14.1 less than LTA)
Don't know how to calculate a ground frost from weather station figures, as lots of factors involved.
Best regards

Not possible unless you have a ground temperature thermometer (at 5cm). I use an old weather station unit sitting on the grass to get mine. A simple cheap data logger would do it also, and if you're willing to manually take readings, a max in thermo approx. 5cm high would do it too.

Here are some of mine.

All the way. Spring was the best period of the year, very dry and sunny. Summer was quite bad, too much rain and specially to much clouds. Autemm was quite good and December very very wet. If December was not that wet I had one of the driest years here. Another "problem" is the heavy thunderstorms during the summer that bring loads of rainfall during a short time. The ground take nothing of that because the drought earlier. However for the garden 2011 was a great, very great year.

Mean Maximum Temperature for 2011: 16.6°C
Mean Minimum Temperature for 2011: 8.7°C
Overall Mean Temperature for 2011: 12.4°C

Highest Maximum Temperature in 2011: 33.8°C
Lowest Maximum Temperature in 2011: -1.0°C

Highest Minimum Temperature in 2011: 21.6°C
Lowest Minimum Temperature in 2011: -4.2°C

Days with frost: 19
Days with maximum below zero: 1
Days with maximums > 20.0°C : 116
Days with maximums > 25.0°C : 31
Days with maximums > 30.0°C : 4
Nights not cooler then 10.0°C : 170
Nights not cooler then 15.0°C : 38
