In which harbor have differences of up to 37 degrees from normal variation been observed?

The significant temperature variations observed in Kingston, Ontario, can be attributed to several factors, including its geographic location and the specific water circulation patterns in the area. Kingston is situated at the eastern end of Lake Ontario, where the confluence of freshwater and various inflows can create distinct microclimates. The presence of surrounding landforms and urban development can also influence local weather patterns and temperature fluctuations. Consequently, Kingston is more prone to experiencing extreme temperature differences, making this location particularly notable for such variations compared to the other harbors mentioned in the question. Understanding these dynamics can help in recognizing why Kingston stands out in terms of temperature anomalies.
