Yellow High Temperature Warnings for Cork as Met Éireann Forecasts More Warm Weather into the Weekend

Met Éireann has issued two yellow high temperature warnings covering Cork, and its latest forecaster commentary points to a continued spell of warm, dry weather this week, with a chance of thunderstorms on Wednesday and Thursday before high pressure reasserts itself for the weekend.

The warnings

The first warning covers Clare, Cork, Galway, Kerry, Limerick and Mayo. It was issued at 7.31am on Tuesday 14 July 2026, with immediate effect, and is due to expire at 7am on Wednesday 15 July 2026.

A second warning, covering twenty counties nationwide including Cork, is due to come into effect at midday on Wednesday 15 July 2026. The full list of counties is Carlow, Cavan, Clare, Cork, Donegal, Galway, Kerry, Kildare, Kilkenny, Leitrim, Laois, Limerick, Longford, Mayo, Offaly, Roscommon, Sligo, Tipperary, Waterford and Westmeath. This warning is due to expire at 6am on Friday 17 July 2026.

Both warnings carry the same criteria: maximum temperatures in excess of 27°C combined with overnight minimum temperatures in excess of 15°C.

Forecaster commentary

According to Met Éireann's forecaster commentary, updated 13 July 2026, the very warm, dry and settled spell will continue this week, with high pressure continuing to dominate. Daytime temperatures will widely be in the 20s, possibly reaching 30 degrees in some places, and it will remain warm and humid at night, with temperatures often not falling below 15 degrees.

Met Éireann said an area of high pressure centred near the Faroe Islands is maintaining the dry, settled and largely sunny conditions, with an easterly airflow bringing a very warm, humid airmass from continental Europe. Temperatures will be highest in the west, south and midlands at first this week, with slightly cooler conditions near eastern coasts as a result of the easterly flow.

Met Éireann said a weak area of low pressure to the south will introduce some instability later in the week. While high pressure will remain dominant, this will bring the potential for heavy showers or thunderstorms in parts of the south and west on Wednesday and Thursday.

Current indications suggest high pressure will remain close to Ireland through Friday and the weekend, with dry conditions persisting. A northerly airflow will become established, bringing slightly lower temperatures to the north and northwest, generally in the high teens, while further south temperatures will remain in the low to mid-twenties.

Impacts and safety advice

Met Éireann has warned of uncomfortable conditions, particularly at night, high or very high UV levels, and an increased risk of heat stress, drought and forest fires, along with increased use of beaches, lakes and waterways as people look to cool down.

Public safety advice from Met Éireann includes:

• Stay in the shade and avoid strenuous activity during the hottest part of the day.
• Drink plenty of fluids.
• Apply sunscreen of at least factor 30 for adults and factor 50 for children.
• Follow HSE guidance on staying safe in hot weather.

For water safety: swim at a lifeguarded waterway where possible, stay within your depth, supervise children closely near water, avoid alcohol before swimming or boating, and check tides and weather warnings before heading out.

For fire safety: do not light fires in or near woodland, fully extinguish barbecue embers after use, and report any fire immediately by calling 999 or 112. The burning of growing vegetation on uncultivated land is prohibited by law between 1 March and 31 August each year.
