“The highest air temperature recorded today was 33.0C in Phoenix Park, Co. Dublin,” the meteorologist said.

“This is a new all-time national record for the month of July and the highest air temperature recorded in Ireland in the 20th and 21st centuries.”

The previous July record for Phoenix Park was 29.5C in 1989.

The highest temperature ever recorded for Ireland was 33.3 °C at Kilkenny Castle in June 1887.

Earlier, the barometer at Phoenix Park had reached 30.1C as Met Éireann warned the public to watch out for scorching conditions across the country.

Temperatures at Dublin Airport also broke an all-time record, hitting 28.9C just after midday, according to Carlow Weather.

Met Éireann’s head of forecasting Evelyn Cusack said today will be the hottest day of the summer.

It comes as Irish Water has been forced to restrict water supplies to 15 areas in the Midlands and South East at night as demand surges during the current heatwave, particularly in holiday hotspots.

And it is urging families to limit use of paddling pools and urging people to take shorter showers where possible to conserve water supplies.

There are currently 12 areas most at risk from drought, mainly in the Midlands and South East of the country including Bennettsbridge and Clogh Castlecomer in Kilkenny, Coalbrook in Tipperary, Clonaklilty, Roberts Cove, Whitechurch and Coppeen in Cork, Wexford Town and Bunclody in Wexford, Inis Oirr in Galway and Swan in Laois.

Since the middle of last week, Irish Water said it was seeing a “noticeable increase” particularly in seaside resorts and farming areas, with demand expected to remain high in July and August.

The utility said that while the vast majority of its 750 water treatment plants continue to meet demand, despite the pressure on water supplies, a number of measures in affected areas such as tanker shipping and/or nighttime restrictions have been put in place to protect supplies and ensure water continues to flow to homes and businesses.

Greater Dublin has good coverage but demand for treated water has risen by an average of 4 per cent in the last week alone.

Irish Water operations manager Tom Cuddy said groundwater sources are slow to recover in some areas and therefore cannot rule out restrictions in other counties.

In addition to the areas where action had to be taken, the utility has a “watch list” of another 65 water supply systems they are keeping an eye on, he told RTÉ’s News at One.

He urged parents to keep paddling pools very shallow if they must be used to cool children down, while homeowners are also asked to avoid pressure washing and keep the garden hose in the shed to conserve their water usage in hot weather to reduce.

Met Éireann’s status yellow temperature warning will remain in place until midnight tomorrow.

The forecaster has warned people to be aware of heat stress, the risk of water-related incidents and the sun’s high UV index, particularly for the vulnerable demographic.

Lead forecaster Evelyn Cusack said this is extreme heat for Ireland as the country’s average maximum temperature is usually 21C during the summer months.

“Today will be the hottest day of the current mini-heatwave affecting Ireland, so we expect temperatures to be around 5ºC up to 10ºC above average,” she told RTÉ’s Morning Ireland.

“Today is a very, very hot day, it will probably be the hottest day of the summer. The highest temperature yesterday was 29.3°C in Phoenix Park, the July record is actually 32.3°C and was set on July 19, 2006 in Elphin.

“So I don’t think we’re going to break that because it’s warm at the moment, the temperature is currently around 18C/19C.

“This little cloud is pushing it down so we could hit 32C, I doubt we’ll break the record but maybe we could.

“I think we should call it a mini heatwave, it’s a hot spell and some people will be happy to hear it won’t last.

“Tomorrow will be very warm and muggy in Leinster, with some fresher weather coming from the Atlantic and there is a risk of thunderstorms tomorrow, particularly over Leinster.”

Tonight will be warm with temperatures between 14C and 18C or warmer locally, particularly in the east.

It will be mostly dry with a mix of clouds and some clear spells, but some showers could develop in the west by morning.

Some haze and fog will develop with mostly light, variable winds, however winds will increase moderately to occasionally fresh from the northwest over the western half of the country by morning.

Tuesday will remain very warm over the eastern half of the country with highs between 22C and 26C. Further west it will be cooler with highs of 16C to 22C.

In the east there are hazy sunny intervals throughout the day and the possibility of isolated heavy showers or thunderstorms developing.

It will become cloudier in the west with some showers of rain, mainly along the Atlantic coast, and the possibility of some heavy rains.

The wind will increase moderately to fresh from the north-westthe whole day.

The forecaster predicts temperatures will return to normal from Wednesday, with fairly dry weather and some showers for the remainder of the week.

Temperatures will return to average on Wednesday with a mix of cloudy and sunny spells and a few scattered light showers in the morning and will be mostly limited to the western fringes in the afternoon.

Highest temperatures are generally between 16°C and 20°C, warmest in the south-east with mostly moderate north-west winds, fresh along the Atlantic coast.

Meanwhile, Water Safety Ireland has urged people to swim at beaches where a lifeguard is on duty after a third water-related death in warm weather last week.

A man in his 60s died on Saturday after getting into trouble while swimming in a lake near Portarlington, Co Laois.

Water safety chiefs have advised people to swim and stay in their depths and swim only between the red and yellow flags on a patrolled waterway.

People should never use inflatable toys in open water as a gentle breeze can quickly carry a person off shore.

Children should always be closely supervised and never left alone near water.

The charity recommends that people who see someone in trouble in the water should shout, grab and throw

Shout to reassure, encourage, and orient them, grab anything preventing you from entering the water like clothing or a stick, and toss them a ring buoy or other floating object.
