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.

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.”
