Best time to visit Czech Republic from the UK
Prague is popular year-round with British visitors. Spring (April to May) is excellent with temperatures of 12°C to 20°C and flowering gardens. Summer (June to August) is warm at 22°C to 28°C with long evenings perfect for al fresco beer gardens in Prague. Autumn (September to October) is beautiful with fallen leaves and comfortable temperatures. Prague's Christmas market (late November to December) is one of Europe's finest and a major draw for British weekend breaks. Winter can be cold at 0°C to 5°C but the city is magical under light snowfall.
