On reflection, I think the six weeks in the latter part of April and early part of May are probably my favourite time of year, closely followed by the equivalent weeks as we go into early Autumn.
The reason for this is simple enough: we often get a spell of pretty decent weather, sunny but not overly hot, with all the bright colours of the change of season.
This contrasts with the supposed Summer, which all too often is disappointing (and where it is not, the alternative can be that it is then far too hot - especially onerous when stuck in an office all day). And Winter these days seems to amount to six months of wind, rain, cold, and general misery (occasionally broken up with just the wrong amount of snow).
So, yeah, I think this week has been just about as good as it gets.
