All are set to bask in temperatures of up to 28C today, and the good news for sun-worshippers here is the hot weather is to continue throughout this week.
The summer finally arrived at the weekend with the mercury touching the mid-20s across Northern Ireland.
And weather experts say there will be more of the same in the coming days with today set to be the hottest day of the year.
"There will be temperatures of up to 28C, with the highest readings in the west of the province," forecaster Paul Mott of MeteoGroup said.
"In Belfast it will be around 26C, so a very warm day with prolonged sunny spells.
"The good weather will last right through the week with temperatures in the mid-20s.
"Every day should reach about 25C or 26C at least.
"Towards the end of the week you may get the odd patchy shower but they shouldn't last very long."
Forecasters say the long-awaited heatwave could last for a fortnight in total.
Yesterday the hottest place in Northern Ireland was Derrylin in Co Fermanagh where it was 24C.
Northern Ireland's top tourist attractions were thronged throughout the weekend.
Beaches across the province were packed including Helen's Bay, Newcastle, Portrush and Portstewart.
And the influx of visitors had the tills ringing in ice-cream parlours, restaurants and bars in coastal towns.
The good weather also brought several hundred people out to enjoy Andy Murray's historic Wimbledon victory on a big screen at Belfast City Hall.
With the warm weather set to continue, the emergency services have urged people to take care when near the sea.
Portaferry Lifeboat was launched four times over the weekend, including the rescue of three children, aged 10, 11 and 14, who drifted from shore in an inflatable crocodile.
Brian Bailie, Portaferry RNLI volunteer lifeboat operations manager, said: "With the good weather and the start of the holiday season it is important that everyone spending a day by the sea takes sensible precautions when using inflatable toys designed for use in a swimming pool rather than the open sea.
"Thankfully on this occasion nobody was harmed, but it could very easily have turned into a much more serious incident."
The Coleraine Coastguard was also busy having been involved in seven rescues since Friday evening, including the hoisting of a father and son up an 80ft cliff to safety.
They had been fishing at the Ramore Head area of Portrush when they became trapped by the tide at around 7pm last night.
Rescuers lowered ropes to the stricken pair who were helped up the cliff.
It followed a similar incident close to Dunluce Castle yesterday afternoon, when a man out walking became trapped by the sea and had to be rescued. A coastguard crew used ropes to help him climb over 50ft.
Derek Thorpe from Coleraine Coastguard urged people to exercise caution when enjoying the current spell of warm weather.
The downside of the good weather for some is that it will also bring a very high pollen count which is predicted to remain until Wednesday.
