Weather forecasters don't expect the heat to last very long and while it may become settled next week the jury is out on whether the heatwave over Europe will push back up over Ireland and Britain as July gets underway.
Met Éireann's official weather forecasting partner, the Met Office, has issued its weekly 10 day weather trend forecast.
The forecaster expects the heat to be shortlived.
In the short term, it expects temperatures to be highest in the western parts of Britain and Ireland on Thursday. It says parts of Ireland could reach the highest temperatures of the year to date.
Friday will remain very warm in Ireland and Britain and temperatures in the UK could hit the mid-thirties on Saturday due to weather-driven up from Africa.
But Friday will be as hot as it will get for Ireland as an Atlantic weather front will cool things off on Saturday with cooler weather from the Atlantic taking full control on Sunday.
Beyond that, into next week, the Met Office 10 day forecast expects high pressure from the Atlantic to bring a lot of fine dry and sunny weather but not a heatwave that will remain lodged over European countries.
The jury is out as to whether the European weather will manage to push back up over Ireland and England next week.
Met Éireann does not issue similar 10 day forecasts. However, it says the national outlook is for the weather is to turn unsettled over the weekend and not so warm from Sunday onwards with near normal temperatures for the early days of next week.
It says current indications suggest for Tuesday and Wednesday somewhat more settled conditions with just isolated showers and temperatures close to normal or slightly above. MORE BELOW TWEET
