Ireland has only had six tropical nights in digital record.
Last night was provisionally the first tropical night in Ireland for 20 years, with Met Éireann's observatory site, Valentia in Kerry, not observing any temperatures under 20.5 degrees.
Tropical nights are when shaded air remains above 20 degrees all night, and are rare in Ireland having only occurred around six times in the digital record.

It comes as the heatwave throughout the country continues to rage on with an orange temperature warning remaining in place until Friday, and a yellow warning extended until Saturday as temperatures are set to climb to 30 degrees in some parts of the country yet again.
As well as Wednesday night being Ireland's first tropical night in 20 years, Wednesday also saw Ireland's highest temperature of the year so far.
A temperature of 30.1 degrees was recorded at Mount Dillon in Roscommon, making it the highest temperature of the year so far.
Friday is set to be another very warm day with plenty of sunny spells, however, there is a risk that heavy showers or thunderstorms will develop in south Leinster and drift through the midlands into south Connacht and north Munster through the afternoon.
It will remain largely dry and sunny elsewhere with showers less likely to occur and highest temperatures generally of 26 to 29 degrees.
The rest of the week is also likely to remain very warm over the weekend, with hazy sunny spells to hit most areas on Saturday.
Temperatures will also be slightly cooler than recent days with highs of 20 to 26 degrees generally.
Sunday will see more sunny spells hit the country with some scattered showers developing in the afternoon and highest temperatures of between 22 to 26 degrees.
Monday should see temperatures get slightly cooler also at between 18 to 23 degrees and the possibility of widespread showers.
