Weather in Sinop

Find out what weather awaits you in the city of Sinop right now. Below are the current data, charts, and a detailed forecast to help you plan the perfect trip.

The climate in Sinop, located on Turkey's Black Sea coast, can be described as humid oceanic or subtropical, which noticeably distinguishes it from the arid resorts in the country's south. The weather here is generally mild and moderate year-round, without extreme heat in summer or severe frosts in winter. The proximity of the sea plays a key role, smoothing out temperature fluctuations and ensuring high humidity levels.

Summer in Sinop is warm and the sunniest time of year, with average temperatures in the range of 20–24°C and highs rarely exceeding a comfortable 27°C. This is the ideal time to visit, as the number of rainy days in July and August is minimal. Winter, on the other hand, is cool and quite damp: the thermometer hovers around 6–9°C, and the sky is often overcast, bringing frequent precipitation.

A distinctive feature of the local climate is the even distribution of rainfall during the transition seasons and winter. From November to March, the highest number of inclement days is observed, so travellers should ensure they have waterproof clothing during this period. Thanks to this moisture regime, Sinop and its surroundings are famous for their lush vegetation and picturesque green landscapes that delight the eye throughout the year.

The climate in Sinop is characterised by its mildness and the absence of sharp temperature changes, which is typical for the Turkish Black Sea coast. The coldest period traditionally falls in January and February, when the average air temperature holds at around +6.9°C. Summer arrives gradually, reaching its thermal peak in August: at this time, the air warms up to an average of +24.2°C, creating ideal conditions for those who dislike extreme heat.

The summer season here can be described as moderately warm and comfortable. Even in the hottest months, July and August, maximum daytime readings rarely exceed +27°C, which favourably distinguishes Sinop from the sultry southern resorts. Winter here is cool but not severe; strong frosts are a rarity. The average minimum on winter nights is around +4.3°C, so ordinary mid-season clothing or a light down jacket is sufficient for walks.

A characteristic feature of the local temperature regime is the very small amplitude of fluctuations between day and night temperatures. The difference is often only 3–4 degrees, providing a sense of stability throughout the day. The transition seasons are also pleasantly mild: by May, agreeable weather sets in with an average of +15°C, while September retains summer warmth (around +21°C), allowing visitors to enjoy the "velvet season".

Precipitation in Sinop is distributed quite unevenly throughout the year, forming distinct periods of high humidity and relative dryness. The highest frequency of rain is observed in the winter months and early spring. The "wettest" month in terms of inclement days is March, when precipitation can occur up to 16 days a month, with January and December following with 15 and 13 days respectively. During this period, prolonged rains or drizzle, typical of the Black Sea climate, prevail.

The summer season, conversely, brings weather stabilisation and a significant reduction in rainfall. The driest and sunniest month is considered to be August, when the number of rainy days drops to an average of 4. July is also favourable for tourism, having only about 6 days with precipitation. If it does rain in summer, it is usually short-lived and quickly replaced by sunshine.

Autumn and late spring represent transition periods with a moderate frequency of precipitation. In September, October, and November, it rains on average 9–10 days per month. Travellers planning a trip during the off-season or winter are advised to bring waterproof clothing and an umbrella, whereas in summer, the likelihood of getting wet is minimal.

When packing for Sinop, it is worth considering the specifics of the mild Black Sea climate. If your trip is planned for summer, when the average temperature stays at a comfortable +24...+27°C, your luggage should be based on light items made from natural fabrics: t-shirts, shorts, and summer dresses. Be sure to bring sunglasses, a hat, and SPF cream, as there is little rain and plenty of sun in July and August. However, even in summer, evenings by the sea can be cool, so a light windbreaker or a long-sleeved top will not go amiss.

For travel during the winter period or the off-season, when the temperature drops to +7...+10°C, the best solution is the principle of layering. From November to March, it rains frequently in the region (up to 15 rainy days per month), so a waterproof jacket with a hood, a warm sweater, and a high-quality umbrella are simply essential. It is also worth ensuring you have waterproof and warm footwear to feel comfortable while walking around the city in damp weather.

Regardless of the time of year, pay special attention to your choice of walking shoes. Sinop invites long walks along the embankment and through historical sites, so comfortable trainers or boots with sturdy soles are your main priority. We also recommend taking a small backpack: it is convenient for storing removed outerwear if the weather clears up during the day, or, conversely, for retrieving an umbrella during a sudden change in weather.
