Bulgaria's Black Sea coast has a maritime climate. Summers are typically hot and dry, but rarely oppressive, with moderate, relative humidity. In the Black Sea coastal regions, including Bulgaria's Sunny Beach, Mediterranean influences temper the harsher continental climate of the rest of the country.
Locals say the area, particularly north of Sunny Beach, has a unique climate due to the combination of sea and mountain air, which they say is most favourable for people with asthmatic and respiratory conditions!!
