WarmWeather in Budapest in May
May is a good time for Budapest if you want warm sightseeing weather rather than reliable heat. Average daytime highs reach 21°C, but nights fall to around 11°C, so this is still a layers-and-jacket trip. The catch is rain: about 12 days have measurable rainfall. For a UK traveller, it offers a warmer city break without usually being too hot for walking, provided you can keep outdoor plans flexible.

Is May a good time to visit Budapest?
May is not the strongest month here: warm days and frequent rain. The best months for Budapest on our scoring are August, July, June; months averaging 25°C or more: Jul, Aug.
Warm afternoons, cooler evenings
The daytime average suits walking around the city without planning your whole day around avoiding heat. There can still be a summer-like feel: 20% of days reach 25°C, so pack light tops and something comfortable for warmer afternoons. Do not assume that warmth lasts into the evening, though. Average night lows are 11.3°C, and the coldest 10% of nights reach 7.5°C or lower. A jumper and a jacket are sensible if you expect to stay out late. May works well if you prefer moderate warmth to intense heat, but it is less convincing if your priority is consistently warm evenings outdoors.
Plenty of daylight, but allow for rain
Rain is the main compromise in May, with about 12 rainy days making a waterproof layer more useful than an optimistically light bag. That does not mean those days are wet throughout, but it does mean a fully outdoor itinerary needs some flexibility. Keep indoor time movable and check the forecast before committing to a long spell outside. There is plenty of scope to rearrange your day: May has about 14.9 hours of daylight, with 6.6 hours of sunshine on average. Expect a mix rather than clear skies throughout. Comfortable shoes that cope with wet pavements will be more practical than footwear chosen only for dry, warm conditions.
