Met Eireann give September heatwave update as Ireland long-range weather forecast will surprise some

Ireland’s latest heatwave came to an abrupt end on Monday as scorching temperatures gave way to thunderstorms and flooding.

The record was broken for the hottest August day ever on Saturday as temperatures peaked at 32C.

The mercury has since returned to more normal levels, with Met Eireann forecasting “unsettled” conditions for the rest of the week, with the weather due to turn “wet and breezy” by the weekend.

However, the national forecaster has not ruled out the return of potential ‘heatwave’ conditions in September.

While Met Eireann says that “forecasts beyond one week become increasingly uncertain due to the chaotic nature of the atmosphere”, it does make four-week predictions to help “give an insight into weather patterns in the month ahead”.

Its long-range weather forecast could surprise some, as it predicts the return of “above average temperatures” at the end of August and start of September.

For the week of Monday, August 29 to Sunday, September 4, Met Eireann says: “While there is some uncertainty, current projections indicate a return to high pressure, bringing generally settled conditions across the country.

“Temperatures are forecast to be above average, with precipitation amounts staying below average.”

The warm weather could also last a fortnight, as the long-range forecast for the week of Monday, September 5 to Sunday, September 11 reads: “Considerable uncertainty remains. As it stands, the long-range model is indicating predominantly low pressure with generally wetter than average conditions across the country.

“Temperatures are nevertheless expected to be warmer than average.”

Until then, Ireland is due to experience more typical weather conditions.

Giving its overall forecast for this week, the meteorological service said: “After a prolonged period of high pressure dominating our weather, low pressure is set to take hold, bringing changeable conditions to the country.

“Temperatures will stay marginally above average, warmest in the southeast. Precipitation is expected to be quite varied with wetter than average conditions in the east and drier than average conditions in the west.”

Looking ahead to next week, it continued: “Air pressure is expected to be very close to average, with neither high nor low pressure dominating. Likewise, temperatures are also expected to stay close to typical levels for the time of year.

“Some uncertainty remains regarding rainfall amounts, although accumulations are currently expected to stay below average for most parts of the country.”
