Generally, the lowest temperatures tonight will be between 8 and 12 degrees, but milder in the south, where the lowest temperatures are forecast to remain between 12 and 14 degrees.

Tuesday is to start off cloudy with outbreaks of rain and drizzle.

Sunny spells and a few showers are to develop in the west and north through the morning and afternoon, and the clearance will slowly spread southeastwards through the day.

Highest temperatures are forecast to be just 11 to 14 degrees, but a little milder further south with highest temperatures of 14 to 18 degrees, Met Éireann said.

Last October, mean temperatures across Ireland were between 11 and 14.5 degrees.
