Luxembourg National Weather Service

Meteolux, also known as the Luxembourg National Weather Service, is the official meteorological authority for the Grand Duchy of Luxembourg. It produces weather forecasts, nowcasts, and long‑range outlooks for the general public, as well as specialised products for aviation, marine, agriculture, and energy sectors. The service issues weather warnings for phenomena such as thunderstorms, heavy rain, snowfall, heat waves, and strong winds to protect life and property. In addition to forecasts, Meteolux collects and archives climatological data that support research, policy making, and climate change monitoring.

Although specific staff numbers or budget figures are not disclosed in the available sources, Meteolux serves the entire territory of Luxembourg from its headquarters in Luxembourg City. Its observational network includes automatic weather stations, radar installations, lightning detection systems, and satellite receiving equipment that together cover the country’s varied topography. The service distributes its information through multiple channels, including its official website, mobile applications, social media feeds, and direct feeds to international meteorological networks. The 2023 incident in which a hacking attempt temporarily took the website offline demonstrated that the core operational systems and alternative communication channels remained functional.

As the national meteorological service, Meteolux holds a regulatory role in issuing official weather warnings that are recognised by civil protection authorities and other governmental bodies. It participates in international cooperation frameworks such as the World Meteorological Organization (WMO) and EUMETNET, enabling the exchange of observational data and forecast models with neighbouring countries. The organisation’s expertise extends to aviation meteorology, where it provides METAR/TAF reports and significant weather charts for Luxembourg‑Findel Airport, and to marine meteorology for the Moselle River and surrounding waterways. These specialised competencies distinguish Meteolux from generic weather providers and embed it within the country’s critical infrastructure.

Meteolux operates as a public institution under the authority of the Luxembourgish government, with its mandate defined by national legislation governing meteorological services. While detailed ownership or parent‑subsidiary relationships are not outlined in the source material, its status as a governmental agency ensures that its primary mission is to serve the public interest rather than commercial gain. The service’s commitment to maintaining reliable observations and forecasts is reflected in its continuous investment in monitoring technology and staff training, even as it works to restore and secure its online presence following cyber incidents.
