In Absence of True Seasons Indeed. April 2010 and 2017 also had a lot of cool but dry and often bright conditions that were better than the cool/dull/wet alternative.
Looking through recent runs, it doesn't seem to matter which direction the weather is coming from, 'trough' is the word for this country. Very stubborn cyclonic conditions in these parts with varying degrees of cool or warmer. Not unheard of at this time of year but very disappointing and definitely not helping the yearning for something more seasonal.
I'm taking a trip to southern Spain in the first full week of May so expect models to pick up on high pressure moving into the UK during that time...
