Values are reanalysis on a grid of about 50 km, corrected to the seat's altitude. On islands and coasts the grid covers much sea, so summer highs on land are usually 1–3 °C above the table.
Heating: about 1,518 degree days a year. A 90 m² middle-floor flat from 1980–2010 would need around 800 litres of heating oil a winter.
