Meteo Sunny Beach in dicembre

Regulars are direct this counts as a genuine gamble by this point, some years bringing amazing weather while the resort itself is largely closed and dismantled by around the 24th regardless of how nice the actual conditions turn out. Our row backs that mild, genuinely dry read, 20C over 11.7C nights feeling 10C, with rain light at 60.5mm across 6.3 days and humidity at 75 percent. Regulars are consistent chilly mornings and evenings are the norm even on a decent, mid-20s daytime stretch, anyone specifically hoping to swim and catch real sun advised to visit at least a month earlier instead. The sea sits at 21.1C. The record: 8.1 hours of sun, an 18 kph wind and AQI 35.

Regulars describe May here as unpredictable and split by the calendar: mid-May can feel too chilly at night for many visitors, and the last weekend of the month is when it visibly picks up as the main tour operators start their summer flights - still quiet compared with July or August, but the shift is real. Our row matches the caution on temperature, 21.3C over 12.4C with 53.9mm across 10 days, and the sea backs their blunt verdict that the water is too cold for most: 15.9C. Sunny warm days do happen, but early mornings and after dark both want a jacket regardless. The record: humidity 77 percent, 12.1 hours of sun, a 17.1 kph wind and AQI 41.

The frame regulars give is worth having before anything else: this is a very short season, opening in June and finished by mid-September. June itself they describe as warm without being overpowering, mid-twenties with the odd thunderstorm that passes quickly, and evenings cool enough for a sweater at around 15 or 16C - our row says 26.7C by day and 17.7C at night across 56.9mm and 9.1 precipitation days. On the Black Sea they are more cautious than our figures: they put it at 17 to 20C while our monthly average reads 22.8C, so expect the early weeks to be colder than the number. Thirteen hours of sun a day and 15.3 of daylight is the compensation. The record: humidity 77 percent, a 16.1 kph wind and AQI 42.

September here is a resort taking itself apart as the month goes on. Regulars describe mid to high twenties with thunderstorms that clear fast and rain that stays local - our row gives 25.5C and 25.3mm across 4.8 precipitation days - plus chilly early mornings and evenings at 16.8C. What changes is the town: places north and south of the centre start closing, the clubs and water parks shut, and by late September it is a quiet, cheap, laid-back version of itself with bargains in the shops but much less open. Their rule is to end the trip no later than the third week if the activities matter, and to come late if the quiet does. The record: humidity 69 percent, 10.6 hours of sun, a 24.6C sea and AQI 39.
