Re: Nov-Dec in London
London is not as cold as the rest of England … and you hardly get any snow in London anyways ! it only snows once a while in January .. and even if it does its not going to be heavy snow , so you dont need any snow shoes ..
but yes winter will be close to peaking in December and chilly winds will make the conditions challenging. Specially for you , since you are coming from Saudi and not used to this kind of mausam and winters ..
I suggest you get one or two heavy cardigans and an over coat .. and once you arrive here you can buy warm gloves, hat and a neck scarf from here.
What you can also do is , get a pair or thermal body clothes , like a pyjama and vest , that will keep you really warm as well ..
its gonna get colder in the evenings since we dont get any sunshine what so ever during december and rain is almost always there ! so yeah that makes the chill harder to bear ..
normal joggers will do along with thick cotton socks ..
Regards the places you wanna visit, totally depends on how much time you have got and how much distance you wanna cover on the Greater London .. what I recommend is that you get the tourist pamphlets available at the airport , they will help you mark a few places of interest.. look up on internet as well ..
And then find out what tube stations are closest to those attractions .. then make a plan accordingly so that what ever area you are in , you can cover the attractions in one go rather then spending time and money on travelling to each one in a haphazard manner …
You can get all this info on the internet ..
Good luck and enjoy your time here
