And Duller Still!

Wednesday’s record dull day for this November was beaten by Thursday which in turn was beaten by Friday.

For comparison purposes I've plotted out three good days in July with their temperature and sunshine records.
Temperature and sunshine records 09 July 2014 to 11 July 2014
With the scales for outside temperature and solar radiation kept the same this is the chart for the last three days.
Temperature and sunshine records 26 November 2014 to 28 November 2014
It’s a bit of a stark comparison three good days in July against three dull days in November but it does show why we struggle to grow plants through the dark days of winter.

If you’d like to see some numbers for this comparison I've added a table of values output by my weather station below.
To finish off I had a look to find the lowest value output over the last four year’s and that turns out to be 14 December 2012 with a value of 0.1 MJ/sqm. Whilst I was checking back through the records I noticed that on 28 November 2010 the temperature fell to -7.6°C so perhaps I shouldn't complain too much about our current dull and damp but reasonably mild conditions.

From the forecast its looks like we might have to wait a few more days for a bit of brighter weather though.
