A changeable pattern is likely through this period, with perhaps a fairly settled start across most parts of the UK, excluding northern areas, where showers are likely to continue, especially in the northwest. As the period progresses, a northwest-southeast split is likely to develop, with perhaps prolonged spells of rainfall and windy conditions arriving to the west and northwest, while an overall dry theme is possible in the east and southeast. Any prolonged settled conditions are likely to deteriorate later into the period, general conditions becoming more changeable with a mixture of rain, showers and some strong winds, interspersed with some drier interludes. Temperatures are expected to be close to or slightly above average through the period, with some cold nights.

A mixture of spells of rain and showers, along with some more dry, settled periods, are likely until the middle of the month, the latter perhaps slightly favoured. However, there could be a trend towards more frequent unsettled conditions as the month continues, which could lead to southern areas being wetter than average for the time of year. Northern areas may see slightly less rainfall than usual though. It is expected that temperatures will generally be above average for October, but, during clearer spells in particular, some nights may feel chilly.
