Tomorrow will be average, yes. The 29 that Tim is enthusing about isn't average, far from it, and will be especially unpleasant to be out and about in. (And yes, I speak from experience - it was 25 when I went four weeks ago and that was enough for the Jubilee line carriage I was on to stink of BO, and the bus back from Kew was especially putrid inside - steamy, and it stank of BO and stale piss. 29 would be even worse.)
London's transport isn't designed for hot weather, other countries where it's hotter (like Japan, or the south/SW in the States) cope much better with it all!
