Best time to visit Prague from Australia

April to June and September to October are the best times to visit Prague. Spring from April to June has comfortable temperatures of 12 to 22 degrees with fewer crowds than summer and the city gardens blooming. Autumn from September to October is warm at 12 to 20 degrees with the vineyards harvesting and the Prague autumn cultural season. Summer from June to August is the most crowded period with temperatures of 20 to 28 degrees and the largest tourist numbers on Charles Bridge and in Old Town Square. Winter from November to March is cold at minus 5 to 5 degrees but the Prague Christmas markets in December are among the best in Europe. Australian school holidays in April align with Prague's most pleasant spring season.
