Has anyone been to Prague, Budapest and Vienna in May? I have been checking the weather daily for the past few months and the forecasts always seem to show rain! Is this like intermittent misty drizzle or is it really rainy and overcast every day? Thanks!
I can't speak for weather in May in these cities but you may want to check out Weather underground for historical information by day in each city.
My experience in Central Europe (including Prague) from mid-late spring is that it rains frequently, but each downpour only lasts about a half hour or so. Expect rain, but don't expect it constantly.
