In Lord Byron's "Don Juan", the author speaks of a man who is forced to leave Spain due to complications related to an ilicit relationship he'd developed with a married woman. Don Juan flees to the Mediterranean and gets involved with another woman whose father ends up selling him off as a slave.
Byron sends his character to all sorts of exotic locations that highly contrast Britan's living conditions and weather. The author paints a picture that presents British people as cold and devoid of passion , which he attributes in big part to northern regions' climate. As he puts it: "In sad reality, / Their chastity in these unhappy climes / Is not a thing of that astringent quality / Which in the North prevents precocious crimes".
Closer to the beginning of the poem, Byron establishes a connection between Don Juan's more open and vivid sexuality, and the climate conditions of southern regions. He's essentially contrasting British folks' prudish tendencies with southern's openness due to the effects of weather and climate.
Hope this helps!
