You can wind the clock back on temperature maps at the link below (albeit most recent map is last friday). Looks like they had a cold spell late december and into the new year but have had milder weather in the last week or so

Sorry for chronicle spam. In short it's just an article about come together and it's intentions to bring huge acts to Newcastle.

Way out west, oya etc.
I personally think they should change the dates, as mid summer they miss out on quite a bit.
Big festivals like Glastonbury, Roskilde, wetchter early summer. Likes of pukkkelpop, creamfields and reading late summer.
Especially the days sziget are on, could pick up plenty of acts over those weekends.
