There may be some cloud and temperatures will be at a low of five to eight degrees, dropping as low as three in clearer areas.
New Year's Day will be cloudy and will see some light rain and drizzle in central parts of the country.
Elsewhere on January 1, Met Éireann says there will be drier and brighter conditions and there will be mild temperatures with highs of six to 10 degrees.
As night falls on New Year's Day, clouds will clear but temperatures will fall and it will turn cold, ranging from zero to minus three degrees across the north and east of the country.
In the south and west, there will be spots of rain with temperatures between three and six degrees.
On Wednesday, Munster and Connacht will see a few sunny spells in between the cloud, with temperatures hitting seven to nine degrees.
