According to forecasters, the clear skies and sunshine should continue right through until Monday evening, with the weather only changing to become cloudier with some showers on Tuesday.
Before that though, it is expected to reach around 23C on Friday, with similar temperatures expected over the weekend.
It has been a welcome week of summer weather, after one of the coldest springs in years.
It hasn't been without its problems though, with gorse fires breaking in areas like Rathlin Island, Divis Mountain and parts of Co Tyrone.
In Belfast, Northern Ireland Water has also been tackling fire hydrant vandalism which has seen thousands of litres flood onto the streets.
Appeals to parents and community leaders are continuing in a bid to stop what may seem like 'harmless fun', but which leaves homes and businesses with low water pressure or no water at all.
"Last night, we had over 100 homes with no water," Sara Venning, Director of Customer Operations at NI Water, said.
"I would like to thank those community leaders and political representatives who have shown us support and would appeal to the whole community to help us before the unthinkable scenario occurs where a fire breaks out and there is no water for the Fire Service to deal with the fire."
NI Water is asking communities to report vandalism to the PSNI or to Waterline on 08457 440088.
