By the beginning of October the resorts of Bulgaria are ending with the velvet season. The sea begins to slowly cool down and swim in it is already uncomfortable. The water temperature at this time is usually + 17-18 degrees. Only in the first half of the month in the shallow resorts of the southern part of the coast the sea remains warm to + 22-23 degrees.

The air also continues to cool, in the daytime, in the sun the thermometer can still show + 18-20 degrees, in the shade + 15-17, but at night the temperature drops to + 10-12 degrees. Much cooler in regions remote from the sea, in the mountains temperatures can drop to + 5-9 in the afternoon and + 2-3 at night. Closer to the end of October at the ski resorts there are the first frosts.

October is more rainy than September. The number of days with precipitation increases by 2-3. Most often they fall on the second half of the month, in the early days the sky is clear, and the weather is dry. In general, the weather in the second autumn month is quite favorable, albeit not for the beach, but for excursion rest.
