Météo-France

Météo-France is the national meteorological service of France, tasked with producing and disseminating weather forecasts, observations and climate information for the country. Its core products include short‑range and medium‑range forecasts, severe weather warnings, marine and aviation meteorological data, and long‑term climate analyses. These products are delivered through multiple channels, including a public website, a mobile application, and dedicated extranets that serve institutional clients such as government agencies, transport operators and energy companies. The organisation also provides teleworking tools that allow its staff and partners to access meteorological data remotely. In addition to routine forecasts, Météo-France issues alerts that support public safety and civil protection efforts during hazardous weather events. Its mission is to ensure that accurate and timely weather information is available to protect lives, property and the environment.

Météo-France distinguishes itself as the official authority responsible for meteorological warnings in France, operating under a mandate to safeguard public safety through reliable forecasting. The service maintains continuous operational capability, as demonstrated during a denial‑of‑service attack on its domain name system in April 2023, when its forecasting and dissemination systems remained functional despite disruption to public websites and mobile access. A prior incident in May 2016 showed that its web presence could be altered through an SQL injection in its domain registrar’s extranet, yet the defacement was corrected quickly without data loss. These events highlight the organisation’s focus on maintaining the integrity of its core forecasting mission while managing external cyber threats. Météo-France’s expertise spans observational networks, numerical weather prediction models and the dissemination of tailored products for sectors such as agriculture, transport and disaster management. Its role as the state‑designated weather service gives it a unique position in coordinating meteorological information across national and international frameworks.
