Sun to shine in last blast of summer
It may be the first day of autumn, but Ireland will get one last flash of summer, as temperatures are set to soar this week.
The good weather comes just days after many children around the country returned to the classroom for the start of another school year.
Conditions will stay mostly dry with some long spells of sunshine, particularly in southern and eastern parts of the country.
Temperatures in September usually range from 12-16C, but the mercury levels are expected to hit as high as 21C tomorrow and on Wednesday.
A spokesperson for Met Eireann said a band of high pressure is causing the sudden return to summery conditions.
