Climate: Finland lies between 60° and 70°N. Rainfall is moderate in most seasons and the temperature is moderated by the Baltic Sea and by the North Atlantic drift. The Asian continental climate that extends to Finland brings periods of severe cold in winter and heat in summer (FMI 2015). Thus almost all of mainland Finland is considered to lie within the thermal limits of the boreal zone, with an average temperature of +4 to −1˚C around the year and a maximum of three months with average temperatures above 10°C (Tveito et al. 2001). The growing season is at its maximum of about 170 days in the south, and the frost-free interval is at most 120 days with a net accumulation of 1300 growing degree days above 5 °C. The brevity of the growing season is thus the main constraint to crop production.
