It can vary - did you look this up on the internet? - There is a lot of info and there are several 30 day forecast sites on the internet.

Time and date now has weather data, at least for some cities:

It can be bright, crisp sunny and cold. It can be very grey and cloudy. It can rain a lot, or be very windy.

Temperatures can vary but it’s not generally as low as freezing as it’s still more autumn than winter. Yesterday there was definitely a cold crispness in the air that surprised me as I left work, but equally well it could be much milder.

The weather is very unpredictable in the U.K. but it generally isn’t extreme.

I’m currently wearing a long warm quilted waterproof coat plus a scarf over normal office clothes and that’s plenty warm enough, if that helps.

This may go some way to describe why UK weather is unpredictable:

The forecast for the next 10 days shows highs near 52 and lows in the 40s. Days should be partly cloudy or cloudy, but it’s the UK, so it can change at a moments notice.

Heed Emma's advice. I spent much of last November in London. Some days were windy, wet and miserable. Other were clear and warm(ish).

Bring layers. You never know what the weather will bring.

Here is the predicted weather:>https://www.weather-forecast.com/locations/London/forecasts/latest

Cold windy and heavy rain this weekend - but then is the Lord Mayor's Show so what else would we expect?

Hope it dries up and the wind drops for 11 o'clock on Sunday for the Remembrance Sunday activity.

You know how we always say UK weather is changeable? At 9am this morning I stood on a street corner in central London waiting to cross the road. To my right, the skies were dark grey and threatening. There was bright sunshine AND rain overhead, bright sunshine to my left and straight ahead it was a mix of grey & white clouds. It was fairly mild. Now this evening it is very crisp and cold.

So - yeah. Bring layers and a good light warm waterproof coat.

This morning I was in my garden in shorts and t-shirt in glorious sunshine but now that it's dark I'm still in shorts and t-shirt but in front of the fire. I'll only resort to 'adult' clothing when the temperature hits single figures.

hello, just wondering what the weather is like, mid November in London

That's next week. Just go online and look it up.
