Can’t comment on the North – but not even close in South Wales – we had an especially good early spring – April was like June/July, since then we’ve the odd wet / windy day, but otherwise warm-ish, dry-ish, clear-ish, mostly over-cast with the odd shower – for my Wife who thinks it’s only Summer if it’s 25c plus and wall-to-wall blue skies it’s been rubbish – for me, who only cares that it’s light enough to ride in to the evening and not knee deep in mud – it’s been great.
Worse Summers I remember are 2007 and 2008, as far I remember, it started raining in early May and didn’t stop until October, honestly it rained every single day, up to the point when trails at Afan which had stood up to every horrible wet Winter in a decade started falling away from the hillside in huge lumps. 2006 was no walk in the park either – if I remember correctly it was so hot that, that was the year we (my mates and I) were setting alarms for 4am to get a ride in before it got too hot.
