When I encountered similar temperatures in Africa, my hosts insisted that I at least bring a jacket. Because it could get even colder later in the evening, sometimes down to a chilling 20C at night (which would be a fairly warm summer night in Sweden).
So I think the delegates will be alright. I guess the meeting rooms all are air-conditioned anyway. A vote for PES is a vote for EPP! A vote for EPP is a vote for PES! Support the coalition, vote EPP-PES in 2009!
