Temperatures will hit 20C in most of the country next week.
Met Éireann says after a mostly dull weekend, it will be a very warm and humid week.
"Latest indications are for very warm and humid weather, with temperatures several degrees above normal, generally into the low 20s," reads a post on their website
For the weekend, Saturday will see mostly dry with warm sunny periods, but with high cloud through the day will make the sunshine a little hazy at times, according to Met Éireann.
Sunday will see heavy thundery rain in the south, however, before the weather improves next week.
Last year saw a particularly warm and dry June, with the highest temperature for the month recorded in more than 40 years.
