Daytime maximum temperatures will generally be between 27 to 30 degrees over the next few days.
Met Éireann has issued a Status Yellow high-temperature warning for Ireland, after record-breaking heat over the past few days.
The warning comes into effect at 1pm on Tuesday and will last until 9am on Friday, following a high-temperature weather advisory that had already been issued at the weekend.
According to the forecaster, the high temperatures will be continuing this week, with conditions hot by day and staying very warm and humid at night.
Daytime maximum temperatures will generally be between 27 to 30 degrees, while overnight temperatures will not fall below 17 to 20 degrees.
In terms of the weather for Tuesday, Met Éireann has said it will be “very warm or hot today” with long spells of sunshine.
That said, the heat may spark off one or two heavy showers across north Connacht and south Ulster towards evening time.
Temperatures will hover between 25 to 29 degrees generally but will be a few degrees cooler along the coasts. Temperatures of up to 30 degrees have been forecast for Wednesday and Thursday.
Meanwhile, Irish Water has advised the public to be conscious of their water use during the current hot period and to avoid excessive use of water, such as watering lawns and taking long showers.
