About 1.2°F per decade, measured from Sinop's official daily weather records, 1973–2025. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.
Is that a lot? Sinop's warming is broadly in line with other cities in Turkey — neither unusually fast nor unusually slow.

Wetter on average

Average temperature for each year from 1973 to 2025.

Each bar is one year. Most recent years sit above the older ones.
Some recent years still came in cool — warming is a slope,
not a straight climb.
When in the year the change shows up
How much warmer each month is now than in the 1970s.
Useful if you garden or care about a particular season —
otherwise the headline above already has the answer.
August has warmed the most — about 3.7°F. The warming runs across the whole year, not just one season.
