As autumn settles in, Dublin is bracing for a significant dip in temperatures this week. According to Met Éireann, the national weather service, residents can expect chilly conditions, with cold nights and daytime temperatures dropping into single digits in some areas. This shift marks the end of milder weather, making way for more typical autumnal conditions in the Irish capital.

A Dull and Damp Start to the Week

The week kicks off with cloudy and damp weather, with early mist and fog affecting much of the city. Dublin will experience scattered showers throughout the day, but there’s a chance of some sunny spells emerging in the afternoon. However, as the evening approaches, a more persistent band of rain may sweep in from the Irish Sea, adding to the already gloomy conditions.

While the northeast winds will remain relatively light inland, they are expected to pick up strength along the East Coast, especially later in the evening. Despite this, daytime temperatures will hover between 16 and 18 degrees Celsius, with the best values likely in the western parts of Dublin.

Cold Nights and Falling Temperatures

As we move further into the week, nighttime temperatures are set to take a plunge. Monday night will be relatively dry with broken cloud, though the northern and western fringes of the country may see some showery rain. Temperatures will drop to lows of 10 to 12 degrees Celsius, with a light northwest breeze ensuring a chilly atmosphere, particularly along the coast.

Cloudy Days with Scattered Showers

On Monday, Dublin can expect a largely dry day, but the skies will remain overcast, with just a few scattered showers here and there. Some sunny spells might break through in the afternoon, offering brief relief from the otherwise grey skies. Highs of 16 to 17 degrees Celsius are forecast, with a light northwest or variable breeze ensuring a relatively cool day, especially compared to recent weeks. The best temperatures are expected further south, where there may be less cloud cover.

Tuesday Brings Hazy Sunshine and Cooler Conditions

As we approach Tuesday, the temperatures will continue to drop. The forecast suggests well-scattered showers throughout the day, accompanied by hazy sunshine in parts of Dublin. Highs will range between 12 and 15 degrees, with a light northwest or variable breeze keeping the cool air in place. Tuesday night may bring more significant rain across the southern half of Ireland, though Dublin could escape the heaviest downpours.

Wednesday: Wet, Breezy, and Cold

Wednesday promises to be a generally wet and breezy day, especially across southern parts of the country. Heavy rain is forecast for the south, though Dublin might see a mix of showers and sunny spells throughout the day. The temperature will continue its downward trend, with highs of 10 to 15 degrees Celsius, colder in the north where the winds will be brisk and coming from the north.

Thursday’s Autumn Chill and Possible Thunderstorms

Thursday will bring some of the coldest conditions of the week. The day will be marked by showers merging into longer spells of rain, with a possibility of thunderstorms. Met Éireann has warned of a chance of hail and lightning, adding to the cold and unsettled weather. Highs will struggle to reach 9 to 12 degrees Celsius, marking a noticeable drop compared to earlier in the week. With moderate northerly breezes, the day will feel particularly cold, and overnight temperatures could dip low enough to bring grass frost in some areas. Clear skies and lighter winds overnight will increase the risk of frost.

A Chilly End to the Week

As we head into Friday, the cold weather looks set to continue. Met Éireann predicts a chilly start to the day, with sunshine breaking through and well-scattered showers expected across Dublin. Temperatures will remain cool, with highs of just 9 to 13 degrees. The northwest winds will continue to blow in cold air, keeping the capital feeling brisk throughout the day. As night falls, Dublin is likely to experience even colder temperatures, reinforcing the autumn chill.

National Outlook: Ireland Prepares for a Cold Spell

While Dublin is bracing for chilly conditions, the rest of Ireland will also experience similar weather patterns. Met Éireann’s national forecast outlines a mix of rain, showers, and cooler temperatures for the entire country.

• Monday Night: The forecast suggests an overall dry night with increasing cloud bringing some showery rain to northern and western regions. Lows of 6 to 10 degrees are expected, with a light northwesterly breeze keeping things cool.
• Tuesday: The day will bring scattered showers and hazy sunshine. Highs will be between 12 to 15 degrees, but it will remain cool, particularly in the north. Rain may develop across the southern half of Ireland by night.
• Wednesday: A dull and wet day is on the cards for many, with heavy rain in southern areas and drier, sunnier conditions further north. Temperatures will remain low, with highs of just 10 to 15 degrees across the country.
• Thursday: A cold and unsettled day is forecast, with showers merging into thundery rain and possible hail. Highs will struggle to reach 9 to 12 degrees, with a moderate northerly breeze. There is also the possibility of grass frost overnight under clear skies.
