Paris, January 5, 2026 – Heavy snowfall across Paris and the Île-de-France region on Monday, January 5, 2026, has led to a complete interruption of bus services and widespread disruption across other public transport networks. The entire Île-de-France region has been placed under an orange alert for snow and ice, causing significant travel complications for residents.
Bus Services Suspended in Paris
The RATP announced the full suspension of its bus network in Paris due to the deteriorating weather conditions. This exceptional measure, implemented during the afternoon, also affects Noctilien night bus services, which are expected to be severely disrupted or cancelled. Commuters are advised to anticipate their journeys and seek alternative transport methods. The decision was made as snow accumulated rapidly, with 1 to 3 cm reported in Paris and up to 7 cm in Seine-et-Marne and Yvelines.
RER and Road Network Under Strain
Beyond the bus network, the RER lines are experiencing significant delays and disruptions. Île-de-France Mobilités reported ‘disrupted’ to ‘severely disrupted’ traffic on several RER lines, with Lines A and B being particularly affected. Lines C, D, and E are also experiencing slowdowns and delays. In contrast, all metro lines in Paris are operating normally, despite a few isolated incidents.
Road traffic has also been severely impacted. By 5:00 PM, over 900 kilometers of traffic jams were recorded across Île-de-France, marking an unprecedented level of congestion. The heavy snowfall, intensifying since 4:00 PM, quickly covered the region in a blanket of white, making driving extremely hazardous. Authorities have implemented a Level 3 snow and ice plan, including reduced speed limits and restrictions for heavy goods vehicles until Tuesday, January 6, at 10:00 AM.
Travelers Face Challenges
The immediate consequence for travelers has been a lack of transport solutions. In areas like Créteil-L’Échat, the combination of bus service suspension and a metro operational incident left many commuters stranded. One user expressed, “I don’t know how we’re going to manage,” highlighting the severe impact on daily routines.
School transport services have also been suspended for Tuesday, January 6, in several departments, including Essonne and Seine-et-Marne, due to the ongoing snowy conditions and anticipated severe frosts.

[paris.evous.fr](https://paris.evous.fr/se-deplacer/info-trafic-greves-travaux-transports.html) also details extensive nightly work and interruptions across various RER and Transilien lines for the week of January 5-11, 2026.
Air Travel Affected
The Directorate General of Civil Aviation has requested airlines operating at Parisian airports to reduce their flight schedules by 15% due to the snowfall. Passengers are strongly advised to check the status of their flights before heading to the airport.
Outlook and Recommendations
Transport authorities strongly recommend limiting travel and regularly consulting traffic information updates. No specific time for the resumption of bus services has been announced, as the situation remains dependent on further meteorological developments and road conditions. The RATP has confirmed that trains will run throughout the night on all tramway lines and metro/RER lines with aerial sections to prevent tracks from freezing.
The weather forecast for the week of January 5 to 11, 2026, indicates intense cold and further snowfall in Paris and Île-de-France, with temperatures ranging between -10°C and 8°C. Commuters are urged to exercise caution and plan their journeys accordingly.
