This lowland stretch between Budapest and Belgrade follows levees, farm tracks, and long open sections across the Danube plain, where sun, wind, and mud shape the days. Starts in April, May, and September align with warm days, cooler nights, and steadier conditions across much of the route. High summer often brings sticky heat and sudden downpours, while late autumn and winter trend colder, greyer, and slower under short daylight and occasional ice or snow.
