Spring between March and May is a good time to visit Budapest: the weather is comfortable; there are no crowds; and room rates are reasonable.

Visiting Budapest on a budget? The best time to visit is during the spring months of March through May as flights and accommodations are generally much cheaper during this time of the year. If you want to experience the most festivals possible in Budapest, plan your visit anytime between June through August for events like the Czech Beer Festival, the Danube Carnival and the Sziget Festival. Want to avoid the crowds? Come to Budapest in October as this is when most of the summer crowds have gone home. Those who are after the beautiful sight of Budapest covered in a blanket of snow, however, must certainly come in January. Verified Resource: The Weather Channel
