Breaking News: Ireland is set for a sharp cold snap early next week, with temperatures expected to fall as low as -3°C overnight on Sunday.
The latest Ireland weather outlook points to a notably chilly night across the country, with frost likely in many areas. Met Éireann forecasts temperatures between -3°C and 1°C from late Sunday into the early hours of Monday.
Cold snap brings freezing temperatures to Ireland
The coldest conditions are expected overnight, when clear spells and light winds could allow temperatures to drop quickly. Rural areas, sheltered locations and places away from the coast may experience the lowest readings.
The change will mark a colder turn in the weather after milder conditions. Drivers, commuters and anyone spending time outdoors should prepare for icy surfaces, particularly on untreated roads, footpaths and exposed bridges.
When will temperatures be lowest?
The main period to watch is late Sunday night into Monday morning. Forecast temperatures range from -3°C to 1°C, although local conditions may produce differences from one area to another.
- Sunday evening: Temperatures begin to fall as colder air settles over the country.
- Overnight Sunday: The lowest readings are expected, ranging from -3°C to 1°C.
- Monday morning: Frost and icy patches may remain before temperatures recover during the day.
What Met Éireann says about wintry showers
Met Éireann forecaster Deirdre Lowe said sleet and wintry showers are likely to be “very isolated”. That means most areas are not expected to see widespread snow or persistent wintry precipitation.
Even where snow or sleet does not occur, freezing temperatures can still create difficult conditions. Moisture on roads and pavements may freeze overnight, especially where surfaces are shaded or poorly treated.
Areas most likely to feel the cold
Temperatures can vary significantly across Ireland. Coastal locations are often moderated by the sea, while inland and higher ground can become colder. People in Dublin, Cork, Galway, Limerick and other urban areas should still be alert to frost, particularly during the early commute.
The forecast remains subject to change as the weather system develops. Localised conditions may differ from the national outlook, so residents should use official regional forecasts for the most accurate information.
What the cold weather means for travel
The overnight freeze could affect road conditions during the Monday morning rush. Motorists should allow extra time and drive according to the conditions rather than relying only on air temperature readings.
- Check the forecast and road conditions before setting out.
- Allow additional braking distance on potentially icy roads.
- Clear frost from windscreens fully before driving.
- Take extra care on bridges, bends and untreated minor roads.
- Pedestrians should watch for slippery pavements and steps.
Public transport users should check service information before travelling, particularly if icy conditions develop in their area. Any disruption will depend on local conditions and operational updates.
How households can prepare for the cold snap
A short period of freezing weather can create practical challenges, especially for older people, vulnerable residents and households with exposed pipes. Simple preparation can reduce the risk of problems.
- Check that heating systems are working properly.
- Keep essential medication and groceries available.
- Use suitable footwear outdoors and avoid untreated icy surfaces.
- Check on elderly or vulnerable relatives and neighbours.
- Protect exposed outdoor pipes where possible.
People should also take care when using portable heaters or alternative heating equipment. Appliances must be used in line with the manufacturer’s safety instructions, and vents should never be blocked.
What happens next in the Ireland weather forecast?
Forecast details may be refined as Sunday approaches. The expected low temperatures are confirmed in the current outlook, but the exact distribution of frost, cloud and isolated wintry showers can change.
Residents should monitor Met Éireann for updated forecasts and any weather warnings. A weather warning Ireland notice would provide the clearest indication of significant hazards, but even without one, icy conditions can be locally difficult.
