Temperatures could rise to 20 degrees on Saturday with mostly dry and sunny spells forecast for the coming days.
The good weather comes as further restrictions are due to be lifted on Monday, with non-contact sporting activities such as golf and tennis set to resume under current Government plans.
Training sessions in other sports will be allowed in pods of 15 for those aged under 18 and zoos, wildlife parks and heritage sites will be able to reopen.
Friday will be dry and bright with spells of hazy sunshine. Conditions will be mild with highest temperatures of 12 to 18 degrees, with slightly cooler temperatures along eastern and southern coasts owing to onshore breezes.
East to southeast breezes will be mostly moderate in strength though stronger at times along Munster coasts.
Friday night will be dry with long clear spells and light easterly breezes. Lowest temperatures will be between 0 to 5 degrees generally, with coolest conditions inland and "perhaps a touch of frost in places", according to Met Éireann.
