It always seemed to be nice in the 90s and early 2000s as soon as the schools went back in Scotland (or at least that was my perception!)
Certainly 1995, 97, 99, 2000, 01, 03 and 04 stand out from that time as having a lot of good weather with 95, 97 and 03 being notably warm, record-breakingly so in the case of 1995 and 2003 (still, I believe, Scotland's warmest ever month and daily max respectively?).
