Weather in London in December
December in London is a coat month. Treat it as cities, food and short walks, not as a terrace holiday.
In United Kingdom, this is how London actually wears December, not how a country centroid would. Compared with July and January, December sits in the middle of London's year.

What to expect
Daytime
You want a proper coat in London in December, not a festival jacket. Wind makes the same afternoon feel sharper than the map suggests.
Outdoor time is the middle of the day. Finish plans before the light goes. Evenings are for indoors.
Rain
December is a wetter month in London. Showers are part of the deal, not a spoiled surprise.
Waterproof shoes matter more than a rain plan for a beach, especially if a beach is not why you came. Build indoor hours into the afternoon.
Evening
Evenings are cooler. A layer helps after sunset.
What to pack
