Get out the sunscreen and the umbrellas - there's a mixed bag of weather on the way.
Temperatures are set to soar over the next week and could go as high as 25C.
Met Eireann said the country should brace itself over the coming days as a mini heatwave takes hold.
The first of the summer weather has arrived, with temperatures rivalling those predicted for Rome.
However, muggy conditions will continue, according to Met Eireann forecaster Klara Finkele.
"Tuesday will be mainly dry along the east coast with a risk of cloud and some light drizzle," she said. "Temperatures of 22 to 25 are on the way, but it will be slightly cooler along the south west coast with 18 to 20 degrees due to a moderate breeze.
"Those with heart conditions should take care as the humidity can be hard to take."
The warm weather will continue through tomorrow, with temperatures reaching well into the mid-20s, though there is a strong risk of showers.
The increased humidity will bring the risk of thundery showers in the south west, where tem- peratures will range from 18 to 25.
Thursday will see heavy scattered showers and slightly cooler temperatures of 18 to 22.
Ms Finkele said temperatures will remain more or less the same on Friday, ranging between 17 and 21, with a chance of some drizzle.
The forecast for the weekend remains mixed and changeable.
Hay fever sufferers should take precautions as the grass pollen risk will be very high throughout the week.
