Romania Bucharest Weather in May — Climate Guide

May is one of Bucharest's best months — proper spring warmth + canonical Romanian Mărțișor traditions already passed + Romanian wine country opening (Dealu Mare + Cotnari spring tours) + pre-summer-school-holiday pricing through mid-May + outdoor culture at full schedules. The May rain (11/month with afternoon thunderstorms) is the main caveat — pack a serious waterproof.
