In January, all three cities where at there lowest temperature. The lowest recorded temperature was City C witch was at -5 degrees Celsius. After January, all cities started to rise slowly going into February by about 1 degree.
Going into the summer ( from March to July) there was a steady increase by about 5 degrees each month throughout all Cities, with City C still being the lowest by the end of the summer at 20 degrees which juxtaposes City A which peaked the highest recorded temperature in that year at 30 degrees. City B (which was at 25 degrees) was the city always in between City A and City C.
Similarly, while entering the winter season there was a gradual fall of about 1-2 degrees going from July to August throughout all cities. Contrastingly to the summer season, there was a larger fall going into the freezing months by about 6 degrees each month till around December.
Going back into January there difference was only miniscule being only 1 degree.
In the end, City A was always the hottest whereas City C was always the coldest. City B being the average between the Three Cities. Overall, there was no anomalies and a well-known seasonal change in temperature. Furthermore, we can assume that the city is in the northern-hemisphere because of the correlation between the months and temperatures.
