Usually, my family and I leave the day after christmas and spend a week for New Years in another city. We're interested in spending our time in London this year, however we wanted to know whether the weather would be too miserable (dark, raining more than usual, etc.)?
New Year in London is always amazing, as in every big city! Don't hesitate! :)
However, you never know with the weather... Typical winter weather in London is relatively cold (0-10°C) and humid. Rain is unpredictable but most of the time short.
I would personally not fear the weather, but always plan indoors activities in case of cold or sudden rain.
The New Year fireworks in London are very popular, however this means that those wishing to see them have to arrive very very early (around 3 or 4 hours prior) in order to get a decent view. And yes, it is very possible that the weather will be raining...I also think the Mayor may be introducing a fee to watch the fireworks...
Alternatively you could walk up Primrose Hill in Regents Park and see the fireworks from there, as there is a wonderful view of central London from the top. There are also many many bars and restaurants to choose from in which to spend your evening.
There is much to see and do during a week in London, especially if you go out to the parks (Hampstead Heath, Richmond Park, Greenwich Park etc) These will look beautiful if it happens to snow.
The weather overall shouldn't be too different from anywhere else at this time of year. But obviously bring warm coats and an umbrella with you just in case!
Anything is possible weather-wise in London, especially that time of year. If you're looking for a spectacle to usher in the new year, finding a spot along the Thames to view the fireworks would be a great thing. Be warned though, any vantage point around London Eye Big Ben and House Of Parliament would be very crowded, as is Trafalgar Square - another NYE hotspot.
