Ireland Poised for Warm and Settled Bank Holiday Weekend as High Pressure Builds

Dublin, July 28 — Ireland is on track to enjoy a final burst of summer sunshine over the upcoming bank holiday weekend, with forecasters pointing to a dominant area of high pressure set to bring warm and settled conditions across much of the country.

According to Met Éireann, high pressure will begin to take hold from Friday, potentially pushing daytime temperatures into the low to mid-20s throughout the long weekend. This marks a welcome change as summer nears its close, with drier and more stable weather also forecast to continue into early next week.

Independent weather analyst Alan O’Reilly of Carlow Weather has been tracking a developing pocket of warm air via social media, noting that it’s likely to move “close to or over” Ireland in time for the holiday. “Some positive signs of high pressure and warmer air to move close to or over Ireland to start August,” O’Reilly posted. “Remember, August is still summer when it comes to meteorological seasons.” While he predicted mainly settled conditions for the weekend, he added that the amount of sunshine remains uncertain, with the possibility of isolated showers.
