The climate of Connecticut (United States of America)
The state of Connecticut is located in the northeastern part of the United States of America and is part of the New England region. Connecticut is one of the smallest states of America. However, Connecticut is the fourth most densely populated state of the 50 states. Connecticut is located in a region where a warm maritime climate in the southerly coastal regions changes into a warm land climate in the interior. Differences in temperatures can especially be noticed during the winter when it is much colder in the interior than along the coast. This is caused by the influence of the Atlantic Ocean which tempers the extreme cold. However, when air is supplied from the cold polar regions it also gets cold along the coast. During the summer temperatures are around 30 degrees Celsius (86.0 degrees Fahrenheit) on average. Peaks in temperatures of 35-40 degrees Celsius (95.0-104 degrees Fahrenheit) are not uncommon. However, on rainy days temperatures hardly rise above 20 degrees Celsius (68.0 degrees Fahrenheit). Winters in Connecticut are fairly mild However, when cold air from the polar regions is supplied it may get extremely cold. During the winter precipitation mainly falls in the form of snow.
