12月のブカレストについての旅行者の声
近くのブラショヴからのメモ(141 km)
ブカレストには12月のメモがまだありません — これは季節を共にする近くのブラショヴについてのメモです。
Brasov-forum threads on December confirm the Christmas market in Sfatului Square, along with smaller markets scattered through the medieval quarter, runs into early January, open until around 1am on New Year's Eve specifically. Posters describe genuine snow cover as unlikely until quite late in the month in a typical year, though regulars call the scenery genuinely magical whenever it does arrive, worth timing a trip around if snow photos matter. The Black Church, old townhall, and the cable car up Tampa hill for a panoramic view over the old town are all named standard December activities regardless of exact snow conditions. Posters call the Schei neighborhood's narrow streets a worthwhile quieter walk away from the busier market crowds. Regulars recommend proper winter layers throughout, temperatures running genuinely cold this deep in the Transylvanian winter. The record: 3.9C days feeling like 1C, -3.4C nights, a notably high 17.3cm of fresh snowfall and 84 percent humidity.

Regulars are blunt that this month can get really, really hot despite still counting as early summer, with several posters saying the conditions here end up barely different from deep August. Our row backs that genuinely hot read, 29.4C reading as a hot 31C, over 14.9C nights, with 91.3mm of rain across 8.5 days and humidity at 66 percent. Regulars are consistent that air conditioning isn't a nice-to-have this time of year but a real booking requirement, several posters specifically warning against older guesthouses that lack it. Evenings do cool down enough for outdoor dining once the sun sets, a real relief after a hot afternoon spent sightseeing. The record: 12.6 hours of sun, a 13.3 kph wind and AQI 50.
July and August are the hottest months here and regulars do not soften it - one calls the August heat unbearable, and locals get out of the city when they can. Our row reads 32.5C at 54 percent humidity, so it is dry heat rather than heavy, with nights falling to 16.1C, a sixteen-degree drop that makes the evenings the usable part of the day. Rain is scarce at 31mm across 3.3 days. Their reassurance is about opening hours: unlike western Europe, nothing much shuts here in August - the museums, shops and restaurants stay open and only the theatres take the month off, so a quieter city is still a working one. The record: 12.1 hours of sun and AQI 44.
Regulars split April here by half: the early part is acceptably warm at 15 to 20C but changes fast - sunny, then cloudy or wet, then sunny again inside a few hours - while by the middle of the month it settles nearer 20C. Our row gives 19.4C days against 4.8C nights that feel like 2C, so the swing is vertical as well as hour to hour, and a coat is still an evening item. Rain is moderate at 52.9mm across 7 days with a trace of snow still on the books. What the month is for is the parks: Herastrau and the open ground on the city's edge, at the point where they turn green. The record: humidity 67 percent, 9.9 hours of sun and AQI 50.
May in Bucharest is warm without being hot, and by late May regulars put it at 25 to 30C - our row's 23.6C average high is the whole-month version, sitting over a 9.5C night that is the part people underpack for. On rain they are precise in a useful way: expect it, but not in quantity, mostly cloud with short showers in the afternoon or evening and lengthy dry stretches between them. Our row's 77.9mm across 9.1 days is that pattern, and it is the wettest month of the Bucharest year. So: something warm over a t-shirt for the evenings and a jacket that sheds a shower. September is the drier alternative they offer. The record: 11 hours of sun, humidity 68 percent and AQI 48.
