Sinop has a typical Black Sea climate due to its location in the Black Sea Region. This climate type is generally characterized by high humidity, abundant rainfall and mild temperatures. These characteristics of the climate significantly affect life and the natural environment in the city throughout the year.
Looking at the seasonal temperature values, winters in Sinop are mild and humid. January is usually the coldest month, with average temperatures ranging between 5 and 10 degrees Celsius. Summers are relatively cool, with average temperatures between 20 and 25 degrees Celsius in July and August. These temperatures are lower than in other coastal regions of Turkey, mainly due to the cooling effect of the Black Sea.
Precipitation regime is a determining factor in Sinop's climate. The city receives more than 1000 mm of precipitation on average per year. The months with the highest rainfall are usually October and November. Although precipitation decreases in the summer months, it is still relatively high compared to other times of the year. In the winter months, precipitation is mostly in the form of rain, but snow can also be seen in the higher elevations.
The winds in Sinop generally blow from the north and northeast directions. These winds carry cool and humid air currents from the Black Sea, which contribute to the city's generally cool and humid weather. Strong winds, especially in the winter months, can affect maritime transportation and fishing and cause increased wave heights.
As for the effects of these climatic conditions on life, high humidity can have a suffocating effect on people, especially in summer. However, cool temperatures alleviate this effect to some extent. Mild winters reduce the need for protection against harsh winter conditions, while a climate with abundant rainfall is advantageous for agriculture. This reduces the need for agricultural irrigation and replenishes water resources throughout the year. However, heavy rainfall can lead to flooding and inundation, putting pressure on infrastructure and requiring additional measures for local governments. Wind impacts are particularly evident in activities on the sea and in energy production (such as wind turbines). This suggests that Sinop's climate has a direct impact on economic activities.
