Irish heatwave: Potential for record-breaking temperatures

Ireland's highest recorded temperature could be broken on Saturday.

Most places will either touch or break through the 30°C barrier, with a fresh yellow high temperature warning having kicked in.

The warning says there will be water safety issues due to increased use of lakes/beaches, as well as a risk of forest fires and "uncomfortable sleeping conditions."

Temperatures on Friday reached 29°C in parts.

Ireland's record temperature is 33.3C °C, recorded in Kilkenny in 1887.

The national forecast said Saturday will be "very warm or hot with temperatures reaching 26 to 30 °C."

The forecaster has also reminded the public to be aware of the UV index and to protect their skin.

They urged people to remember the 'SunSmart 5S; rule:

• Slip on clothes that cover your skin, such as long sleeves and t-shirts with a collar.
• Slop on broad-spectrum water-resistant sunscreen,  factor 30 for children, factor 50 for adults.
• Slap on a wide-brimmed hat to protect your face, ears and neck.
• Seek shade, especially if outdoors between 11am and 3pm
• Slide on wraparound sunglasses with UV protection to protect your eyes.

Sunday is also set to be a scorcher, starting with good sunny spells in the morning.

Cloud will build from the west with showery outbreaks of rain pushing in across western and southwestern parts during the afternoon and evening.

Some heavy and possibly thundery downpours are possible, Met Éireann say, with a very warm or hot day with highest temperatures of 22 to 29 °C.

The Department of Agriculture, Food and the Marine has also issued a Condition Red Forest Fire warning.

They say they want to highlight the dangers to resources and public safety arising from vegetation fires, on and around forests and other public recreation sites, especially those close to urban areas.

Visitors to forests, parks, beaches, and other recreational areas are asked not to bring barbecues and sources of ignition and to be mindful of parking and access to these areas by emergency services.
