Last night was provisionally the first tropical night in Ireland for 20 years, Met Eireann have confirmed.
Temperatures in Valentia in Kerry didn’t drop under 20.5 degrees celcius.
Tropical nights occur when shaded air remains above 20 degrees for an entire night.
These events are extremely rare in Ireland and have only happened approximately six times since records began.
The news comes as the country continues to be immersed in a heatwave, with an orange weather warning remaining in place until Friday, and a yellow warning in place until Saturday.
The warm spell looks set to continue for the rest of the week, with some thundery showers occurring over the weekend.
