Winter - 2010, including Dec 09, most wintry overall since 78-79.
Spring - 2011, a dry March and April combo and warm, May turned wetter. The other seasons were poor, would have said winter, but Feb was mild and wet.
Autumn 2012- very seasonal, lots of frost, early snow in late Oct and a cold end
Summer 2013, best since 2006 and much needed. July was excellent.
Summer 2014, despite a very poor August, June and especially July were great.
Winter 2015, struggled with this year, none of the seasons stood out, all quite mixed, but the winter brought alot of polar maritime air and snow at times.
Autumn 2016 , a very warm Sept, a cold frosty Nov, October I can't remember much of
Spring 2017, a very dry and mild March and April combo, I think May was quite reasonable as well. I quite liked the autumn as well very seasonal.
Summer 2018 , super June and July, imploded in August, if included May, best 3 month spell of the 10s.
2019 - can't choose, none stood out better than the other.
