Steppes are usually characterized by a semi-arid or continental[citation needed] climate. Temperature extremes can be recorded in the summer of up to 45 °C (115 °F) and in winter of down to −55 °C (−65 °F). Besides this major seasonal difference, fluctuations between day and night are also significant: in both the highlands of Mongolia and northern Nevada, 30 °C (85 °F) can be reached during the day with sub-freezing readings at night.
