It's a mixed bag for Halloween with some rain and showers around and it will be starting to feel quite chilly, so wrap up warm if you're heading out. Expect temperatures of around 6C but it may become chillier still in rural parts. Where the breeze falls light, there could be some mist patches forming by dawn.
Rain will arrive in southern parts by the end of the night signalling the next band of rain arriving. This will push further north during the morning. By the afternoon the whole of Wales will have seen some rain, and central and southern parts will see a spell of heavier rain for a while. Temperatures are about right for the time of the year with highs of 10-13C, however, it will feel cooler in the breeze.
The next few days see more spells of rain and showers across Wales. Temperatures remain around 12C but it will be breezy and blustery.
