Editing Greater Poland Voivodeship (section)

===Climate===
Wielkopolska is influenced by oceanic air masses that affect the mildness of the climate. The farther east one travels the more distinctly continental the climate becomes. The area is situated in the Silesian Greater Poland agro-climatic region where the average annual temperature is about 8.2&nbsp;°C, and in the north drops to around 7.6&nbsp;°C. It is slightly warmer in the south and west where the average temperature is usually about 8.5&nbsp;°C. The number of days with snow can reach up to 57 days in and around the [[Kalisz]] district.

The growing season is one of the longest in Poland. On the province's southern plains this season constitutes around 228 days, while north of Gniezno and [[Szamotuły]] this gradually declines to 216 days.

Precipitation ranges from 500 to 550&nbsp;mm. Despite this the region is still faced with a deficit in rainfall, particularly in the eastern part of the province (around Słupcy, Kazimierz Biskupi, Kleczew) where sometimes experience only 450&nbsp;mm of rainfall per year, this threatens steppization of the region. Throughout the province there is typically a prevailing westerly wind.
