Answer for When is it the best to visit Budapest?

Budapest’s peak season runs from May to September, but with July and August often verging on the oppressively hot. The city does, however, have a wealth of baths that are a godsend when temperatures soar. May, June, and early September are usually ideal temperature-wise.
August is a major vacation month so be prepared to find a fair number of restaurants, bars, and shops shut.
Budapest is a good all-year destination and despite its cold winters there are plenty of indoor activities, plus outdoor novelties like skating and shopping at a Christmas market. Hotel prices are significantly cheaper in the off-season and the city is less overrun with tourists, making a strong case for an off-peak visit.
