Ireland is transitioning from a record-breaking heatwave to a period of unsettled, more typical weather as Met Éireann issues urgent warnings for both thunderstorms and safety hazards. A thunderstorm alert is currently in effect for Cork, Kerry, Limerick, Waterford, and Wexford, running from 2:00 p.m. To 7:00 p.m. On Wednesday.
The forecaster warns that scattered thunderstorms moving up from the south could result in severe conditions, including lightning, hail damage, and impaired visibility on the roads. This follows a period of extreme heat that saw provisional records tumble; a station at Shannon Airport recorded 30.5 degrees on Tuesday, while automatic climate stations in Clonmel logged 30.7 degrees.
A Shift in the Weather Pattern
Meteorologists expect the current high-temperature spell to conclude as airflow patterns shift back to a westerly direction. Forecaster Gerry Murphy indicated that temperatures will drop to high teens and low twenties—typical levels for May—by the upcoming bank holiday weekend.
The transition will bring a mix of sunshine, clouds, and rain. Thursday is expected to be cloudier with potential showers in the south and west, while Saturday and Monday are forecasted to see more significant rainfall.
Safety Amidst Extreme Conditions
Authorities are emphasizing water safety as the public continues to utilize lakes and beaches. Linda Jean Byrne, water safety lead for the RNLI, warned that water temperatures remain cold—well below 15 degrees—despite the heat on land. This discrepancy can trigger cold water shock, leading to involuntary panic and a loss of breathing control.
In the event of an emergency, the public is advised to “float to live,” staying calm and avoiding the instinct to thrash. Bystanders witnessing an incident should prioritize contacting the Coastguard via 999 or 112 before attempting any rescue from a position of safety.
