Ireland is preparing for its coldest night of the season so far, with an Arctic air mass expected to send temperatures sharply lower after dark on Thursday. Met Éireann says snow is not expected, but frost, icy patches and black ice could create difficult driving conditions into Friday morning.
Coldest night of the season forecast for Ireland
The latest Ireland weather outlook points to a clear, calm and very cold night across much of the country. Met Éireann forecaster Deirdre Lowe said there would be no precipitation overnight, meaning snowfall is not expected, but temperatures will fall quickly once darkness arrives.
The midlands are likely to experience the lowest readings, with temperatures dropping to between -3 and -4 degrees. Coastal areas will also become exceptionally cold, with temperatures expected to remain close to freezing.
This will be the first significant frost of the season for many parts of Ireland. Drivers may need to clear ice from windscreens before setting out, while untreated roads and footpaths could become slippery.
Black ice risk for Friday morning commuters
The combination of freezing temperatures and calm conditions may lead to icy patches, including areas of black ice that can be difficult to see. The greatest risk is likely on untreated rural roads, bridges, exposed surfaces and quieter routes.
- Allow extra time for journeys on Friday morning.
- Reduce speed and leave more space between vehicles.
- Take particular care on bridges, bends and shaded roads.
- Check windscreens and mirrors before travelling.
- Pedestrians should watch for slippery pavements and crossings.
Ireland weather forecast: What to expect next
Friday will begin with widespread frost, but conditions are expected to remain settled and gradually improve during the day as cloud clears in some areas. Afternoon temperatures will range from 5 to 8 degrees.
Cloud is expected to develop in the west later on Friday, bringing another frosty night. Temperatures should become slightly less severe on Saturday, when highs of 8 to 11 degrees are forecast.
Rain and some hill sleet expected on Sunday
The weather pattern will change on Sunday, with rain moving across the country from the west. The rain is expected to clear towards the east during Sunday evening.
Some sleet may fall on higher ground in northern areas on Sunday night. Met Éireann described the outlook as having a “wintry flavour” on the hills, although widespread snowfall is not forecast.
Monday is expected to be mainly dry, with sunny spells and temperatures reaching between 6 and 10 degrees.
Why temperatures are falling so sharply
The cold spell is being driven by an Arctic air mass moving across Ireland. Under calm conditions, heat escapes from the ground quickly after sunset, allowing overnight temperatures to plunge, particularly inland.
Inland regions generally cool more rapidly than coastal areas because the sea helps moderate temperatures. Clear skies and light winds can intensify the effect, producing sharp ground frost even when daytime conditions appear relatively mild.
The forecast also reflects the difference between air frost and ground frost. Air frost occurs when the temperature measured above the ground falls below freezing, while ground frost can form when surfaces become icy even if official air temperatures remain slightly higher.
What does the forecast mean for people across Ireland?
For most residents, the main effects will be a cold start, frozen windscreens and potentially hazardous local travel conditions rather than disruption from snow. Public transport users should still check journey information, particularly if they are travelling early in the morning or through inland areas.
Households may also want to protect vulnerable plants, check outdoor water supplies and ensure older relatives or neighbours are prepared for the colder conditions. Anyone walking or cycling should use extra caution on untreated surfaces.
Frequently asked questions
Will it snow in Ireland tonight?
No. Met Éireann expects a calm night without precipitation, so snow is not forecast overnight. Some sleet may affect higher ground in northern areas on Sunday night.

The midlands are expected to record the lowest temperatures, potentially falling to -3 or -4 degrees. Coastal areas will also be close to freezing.
When will temperatures rise?
Temperatures are expected to become milder on Saturday, with highs of 8 to 11 degrees. Sunday will bring rain and winds from the west, followed by a mainly dry Monday.

Icy patches and black ice are possible, especially on untreated roads and exposed surfaces. Drivers should slow down, leave extra distance and allow additional time for journeys.
Key takeaway
The latest Breaking News Ireland weather update is a warning about frost and ice rather than snow. Thursday night is expected to bring the season’s lowest temperatures so far, with the midlands facing the sharpest freeze. Anyone travelling early on Friday should prepare for icy conditions, while a wetter and slightly milder pattern develops through the weekend.
