Ireland’s all-time high temperature record could be broken on Saturday.
Many areas are forecast to reach or exceed 30C this weekend, prompting a fresh yellow high temperature warning beginning at midday.
The warning highlights potential water safety concerns due to increased use of lakes and beaches, as well as a risk of forest fires and “uncomfortable sleeping conditions.”

Ireland’s highest temperature ever recorded is 33.3C, which occurred in Kilkenny in 1887.
The national forecast for Saturday states: “Today will be very warm or hot with temperatures reaching 26 to 30C.
“Any patchy fog in the southwest will clear quickly and it will be dry and sunny with light to moderate southeasterly winds.”
The national forecaster has also advised the public to be mindful of the UV index and to take precautions to protect their skin.
They urge the public to remember the ‘SunSmart 5S’ guidelines:
- 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 forecast to be very warm, starting with sunny spells in the morning.
Cloud will increase from the west, with showery outbreaks of rain spreading across western and southwestern areas later in the day.
Met Éireann warn some heavy and possibly thundery downpours are possible, with temperatures expected to be between 22 and 29C.
In addition to Met Éireann’s warning, the Department of Agriculture, Food and the Marine has issued a Condition Red Forest Fire warning.
They emphasize the dangers to valuable resources and public safety associated with vegetation fires, particularly in and around forests and other public recreation areas, including locations near urban centers.
Visitors to forests, parks, beaches, and other recreational areas are asked not to bring barbecues or any other potential ignition sources to these locations and to be aware of parking and access restrictions for emergency service vehicles.
Minister of State at the Department Michael Healy-Rae stated: “Everyone has a duty to protect these areas and our rural livelihoods from the risk of fire. We want people to enjoy themselves responsibly, but to leave the barbecues and campfires at home this weekend.”
