Belleville is a small city located in the southwestern part of
Illinois in the vicinity of the Mississippi River. Belleville is
located in St. Clair County. The city was founded at the beginning of

entire population of Belleville consisted of Germans. Many typical
German houses can still be found here and the typical Oktoberfest is

More climate information
Climate figures are very useful but don’t present a general impression
of the climate and the eventual weather circumstances within a certain
period. The figures don’t always reflect the chance of wintry weather,
extreme heat or hurricanes. That is why we offer useful extra climate
information for each month of the year:
