London weather: Capital set for a mild October according to long-range weather forecast
Plus the coldest day of the month should fall on Halloween!
And just like that, it’s October - often regarded as the greatest month of the year (and no, that’s not just because it’s my birthday!)


October marks the official start of autumn here in the UK. It’s time for Halloween, dark evenings, twinkling lights, and it's the gateway to the sparkly season - all things we love.
As the evenings draw in and the temperature starts to drop, it's a good chance to look ahead at what the weather we can expect here in London is like for the month ahead.
The overall outlook for October in London is mild and cloudy with a few sporadic rain showers.


As of today (October 1st), the sun will set at approximately 6:40 pm, and temperatures will remain in the high teens to low 20s.
According to AccuWeather, the first two weeks of October will remain predominantly dry, bright, and mild, with highs of 19 °C on the 1st, 2nd, 3rd, and 7th.
Some rain showers are forecast for Monday, 5th October. The rest of the month looks considerably dry with highs of around 17 °C in the middle of the month.
Temperatures will start to drop off, and clouds will become more frequent towards the end of the month. The coldest day of October will fall on Halloween (31st) at 11 °C.
It will start to get cold overnight, about halfway through the month, with highs of 13 °C and lows of 3 °C.


The Met Office says: “This period (4th-13th October) could begin with some very disturbed weather for the British Isles, with a deep low probably passing to the north or northwest of the country.
“This means there is potential for powerful winds and some further heavy rain, especially, but exclusively, for more northern areas. Over the following week, a broadly westerly type of weather is most likely, with additional weather systems moving in from the Atlantic.
“On balance, southern areas stand a better chance of seeing longer drier interludes. However, confidence in the details remains low, owing to ongoing Atlantic tropical cyclone activity.
“Overall, temperatures will probably be fairly close to average by day and whilst some overnight frost cannot be ruled out, especially later in the period, nothing overly cold is signalled at this stage.”
