Forecaster Met Éireann has said the sunny weather enjoyed by the country over the last week is set to last until at least Tuesday.
Yesterday's summer solstice - the longest day of the year - saw the country once again bathed in warm, sunny conditions.
However, forecaster Gerry Murphy says there could be showers later in the week.
"The really good weather is certainly going to continue for today, Sunday," Mr Murphy said.
"Also for Monday and Tuesday we will see temperatures getting into the high teens and the low 20s.
"Then I'm afraid we will see the beginnings of a change on Wednesday.
"Later on on on Wednesday we do expect to see some rain, and then some showers on Thursday.
"So it does look as if we will see a break in this really good spell."
Meanwhile Irish Water Safety are advising parents taking advange of the fine weather to keep a constant eye on children playing in or near water.
The calls come after a 13-year-old boy died in a tragic swimming accident in Dublin on Friday.
Ricky Osagie went to the aid of a girl who got into difficulty while swimming in a lake in Blanchardstown on Friday evening, and died in Temple Street Children's Hospital on Saturday morning.
