What happened

Met Éireann has put a Yellow Fog Warning in place that covers Munster from 10pm on Friday 6 November until 10am on Saturday 7 November 2026. The warning notice says widespread fog is expected, with dense patches possible that will reduce visibility and create hazardous travelling conditions across the region. Cork Beo reports the same notice also covers parts of Leinster and Galway.

The warning arrives during long, dark nights and calm early-morning conditions, which increase the risk that fog will linger on low-lying roads and coastal approaches. Met Éireann forecasts the lowest temperatures tonight will be between 2 and 5 degrees Celsius, conditions that favour mist and patchy freezing is not expected but visibility problems are likely.

What it means for Irish drivers

Drivers should assume visibility could fall to very low levels on many routes across Munster between 10pm and 10am and plan journeys accordingly. Slow down, use dipped headlights or fog lights where appropriate, and increase stopping distances - standard braking distances are not safe in dense fog. Avoid using main beam headlights because they reflect off the fog and can make it harder to see.

If possible, delay non-essential travel until the fog clears. For essential trips, allow extra time, check routes for local advisories and consider alternative travel times; according to the Met Éireann notice the fog should start to lift through Saturday morning as light winds develop. Keep a charged mobile phone, tell someone your route, and be prepared for sudden changes in visibility on bridges, estuaries and valley roads.

Practical tips and local impacts

On motorways and primary routes drivers should use the hard shoulder only in an emergency and follow variable-message signage. If you become disoriented, pull over safely where you can fully clear the carriageway, switch on hazard lights and remain in the vehicle until conditions improve. Watch for slow-moving agricultural machinery on rural roads where fog is denser.

Public transport and ferries may experience delays or altered timetables in the early morning; if you rely on trains or buses check the operator updates before travelling. Weekend plans that depend on early starts, such as ferry crossings or long-distance commutes to airports, should be reviewed and departures pushed back where possible to avoid the worst of the fog.

Looking ahead

Cork Beo notes that once the fog warning expires, weekend conditions should improve with bright, dry and relatively mild weather developing from Saturday lunchtime. Temperatures are expected to reach up to around 12 degrees in Munster on Saturday afternoon, with Sunday remaining mostly dry though a little cloudier.

Longer term, Cork Beo cites Met Éireann in saying Atlantic systems will push across Ireland early next week bringing unsettled weather and the chance of heavier rain, while daytime temperatures may remain mild for the time of year. Keep an eye on Met Éireann updates if you have travel scheduled beyond Saturday.
