The () can also steer winter storms, with a typically bringing mild, wet westerlies to northern Europe. The current ENSO state is Neutral, with an anomaly of -0.16°C for January-March 2026, though forecasts suggest a likely transition to El Niño by May-July 2026, which could influence future weather patterns. In January 2026, Luxembourg experienced cold and snowy conditions, with MeteoLux issuing a yellow weather warning for temperatures as low as -10°C and fresh snow accumulations. However, by March, the weather shifted to dry and sunny conditions with afternoon temperatures reaching 15-17°C.
Looking ahead
Forecasters suggest a likely transition to El Niño by May-July 2026, which could bring warmer global temperatures.

Where does the climate data for Luxembourg come from?
Climate data for Luxembourg comes from Our World in Data, sourcing Copernicus ERA5 and HadCRUT5 (national temperature anomaly) and the Global Carbon Project via Our World in Data (CO₂ emissions), refreshed every month, when the upstream temperature and rainfall data are refreshed.
What is the climate baseline used on this page?
Anomalies on this page are calculated against the 1961-1990 climatological baseline, which is the standard reference period used by the Met Office, NOAA, IPCC and most national climate services. Some panels also show the source-native 1901-2000 (NOAA) or 1991-2020 (WMO) baselines for verification. See Methodology & Sources for the full reference.
