Punters are being advised to wrap up warmly and have their umbrellas on hand, as Met Eireann is predicting mixed conditions as the day progresses.
"There will be plenty of showers expected throughout the day, it is very unsettled right across the country, but it is looking like that rain will clear for a few hours in the late afternoon, especially on the east coast of the country," Met Eireann forecaster Harm Luijkx told the Irish Independent.
Tonight is expected to be cold, with wet and windy weather continuing into New Year's Day.
This year has seen the biggest build-up to countdown ever.
As part of NYE Dublin, #LoveDublin Day took place yesterday, staging a string of free cultural events.
The History Ireland Hedge School held an interactive talk on Dublin's Literary Past and Present in The Little Museum, while the Smock Alley theatre played host to some of Ireland's literary greats, with panellists, including Christine Dwyer Hickey, Michael O'Loughlin and Dermot Bolger, participating in a series of live discussions.
"It's nice that there is so much happening, because Christmas used to happen in a day," Mr Bolger told the Irish Independent.
"Nowadays the cusp period between Christmas and New Year's has been filled and there are events happening, people can reflect upon the arts and the city."
