Year 2019

New Year's Day sunshine out over Lyme Bay

A little warmer and much wetter than normal with around average sunshine.

It was a strange year in so many ways but as always, rather interesting weather-wise. It started a happy one with a beautiful spring and a stunning July but things took a downturn for the second half of the summer. My father died suddenly in September and it was a shock to us all and now he has left a big hole in our lives. He loved Devon and the weather was an inspiration to him as much as it is to me. Then the year ended with a lost opportunity. An opportunity to right the wrongs and to try and tackle one of the biggest issues facing mankind, climate change. But it was not to be and now things have taken a different, more sinister turn.
