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:
