Today: fog clears to sunny spells

Early mist and fog patches are expected in rural spots first thing, but they should steadily clear to leave a dry day for most, with sunny spells breaking through. There is a chance of the odd shower along southern coasts at first. Winds stay light and it will feel mild, with a maximum temperature of 15°C.

Tonight: light winds, a few fog patches

A dry night follows, with variable cloud and clear spells. Winds remain light, and the odd mist or fog patch may form again in prone spots. The minimum temperature drops to around 5°C.

Friday: bright and dry

Early low cloud clears to leave a bright and dry day for many, again with light winds. Temperatures stay close to the average for the time of year, with a maximum of 15°C.

Saturday to Monday: dry for Halloween, cloudier by Monday

The fog risk sticks around overnight and may linger through the morning at times. Otherwise it stays dry and sunny on Saturday and Sunday, which is welcome news for anyone out on the doorsteps for Halloween on Saturday 31 October. That settled spell then begins to break down, turning cloudier as Monday 2 November comes in.
