Ireland has experienced its hottest May day on record, with temperatures reaching 28.8C at two automatic climate stations, according to Met Eireann data. Killarney and Clonmel both recorded the new high at approximately 3pm on Monday, surpassing the previous record of 28.4C set on May 31, 1997, at Ardfert Liscahane in County Kerry.
Warm Weather Continues
The national meteorological service forecasts long spells of sunshine across the country, with temperatures largely between 23C and 28C. The warm spell is expected to persist, with highs of up to 28C on Tuesday and 27C on Wednesday. In the UK, the hottest May day was recorded at Heathrow, west London, reaching 33.5C. Met Office observations also placed parts of Northern Ireland between 24C and 25C after lunchtime.
Health Warnings Issued
Amid the heatwave, the Irish Cancer Society has urged the public to protect their skin from harmful ultraviolet (UV) rays, the primary cause of skin cancer. Michelle Lonergan, a cancer awareness nurse at the charity, emphasized that over-exposure to the sun can damage skin at any age, with damage accumulating over time and increasing the risk of melanoma and other skin cancers.
“Even on cloudy or cooler days, UV rays can still penetrate the skin, making daily protection essential whenever you are outdoors,” Lonergan said. She recommended simple steps such as regularly reapplying broad-spectrum sunscreen with a high SPF (30 or above), wearing lightweight long sleeves, sunglasses, and a wide-brimmed hat. Special attention should be given to babies and children, as their skin is more sensitive to the sun.
