If I came to London I'd probably come end of this year/begining of next so I'd be arriving mid summer I guess.
Na mate, theres this thing called seasons. Northen Hemisphere season would be the opposite of a Southern Hemisphere season. So it would be a NZ summer to a UK winter, and you would be arriving smack bang into a cold, dark winter.
However, first attempt in London hated it. Second attempt loved it as soon I was off the plane.
You will be fine Itchy. Not as if you dont know anyone there. Do it!
