Weather history in Belgium: stations, records and trends

This section brings together the long climate records of 12 weather stations in Belgium, with observations going back to 1795 and running up to 2025. Each station has its own page: temperature and rainfall for every year, a comparison of two thirty-year reference periods (1961–1990 and 1991–2020), dated records, the trend and the last twenty-four months. The stations are listed below by 9 administrative areas. Across all stations, the warmest year is 2011, at +1.9 °C against the 1961–1990 average (10 stations reported that year). The median trend of annual temperature reaches +0.36 °C per decade since 1961.

Departure from the 1961–1990 average, all stations

The thin line shows each year's mean departure, from 1954 to 2013; the thick line is the ten-year running mean. Every station is compared with its own 1961–1990 average and the departures are then averaged, so station altitude and latitude do not distort the comparison.
