The country is set to bask in sweltering temperatures with forecasters predicting temperatures to soar to 31C by the end of next week.
Temperatures are set to increase as the week goes on and peak on Thursday and Friday.
Met Éireann forecaster Siobhan Ryan has said Ireland could possibly expect record breaking temperatures for the week ahead.
"Wednesday through to Friday we’re going to see the hottest spell so far this year, with temperatures readily in the mid to high 20s.
"We’re probably going to see temperatures of 30-31C reached," she added.
The hottest conditions will be experienced over the midlands, while coastal areas will experience a refreshing sea breeze.
"The highest ever temperature in Ireland was recorded in 1887 in Kilkenny, during that day we saw a temperature of 33.3C recorded," Ms Ryan said.
She added: "This week, we’re looking at temperatures by all accounts climbing into the high 20s, and there is every chance we could see 30-31C reached in some parts and maybe even higher.
"Temperatures each consecutive day are going to continue to build".
The forecaster added that Ireland can expect a heat wave over the week.
"More than likely it’s going to be a heat wave, the definition of a heat wave is actually five consecutive days where temps are 25C or higher across the country, so by all accounts that is going to happen in the week ahead," she said.
Met Éireann has also said that nights will be warm too, with minimum temperatures expected to be in the low to mid-teens.
The highest temperature this year in Ireland was recorded today by Met Éireann in Oak Park in Carlow.
The temperature reached 26.5C, making it the hottest temperature for Ireland this year to date.
There was a high of 26.3C at Shannon Airport, and Phoenix Park reached 24.5C.
Along the coastline, temperatures were cooler with 21.4C recorded at Valencia in Kerry and a high of just 14.3C at Mallen Head.
Tomorrow, temperatures are expected to hit a high of around 27C.
