Temperatures are forecast to rise to the mid and high 20s later this week, according to Met Éireann, with Ireland set to be affected by a weather phenomenon.
The forecaster said: “The Azores High will build this week with warm and settled weather to come – becoming very warm or even hot from Thursday”.
The Azores High, which originates in the Azores off the coast of west Africa, is a large atmospheric high-pressure centre that develops over the subtropical region of the eastern North Atlantic ocean.
It pushes high pressure up from the south and displaces the jet stream which usually brings with it Atlantic fronts and unsettled weather.
