Most of the country sits roughly between about 200 and 500 metres, which is why Prague and Brno feel like full four-season cities rather than Alpine bases: Living in Prague and Living in Brno. Summers warm into the 30°C band in South Moravia and other lowlands; winters bring frost and slush more often than deep resort snow: Summer heat and Winter cold.

Sněžka at about 1,603 metres sits in a different temperature world from southeast Moravian vineyards on the same day.
