To sum up Detroit's weather in one phrase, it would be that 'all four seasons exist, but winter is quite long.'

The climate type falls under the Humid Continental category. In January, the average high temperature is about 31°F (−1°C), while the low is around 18°F (−8°C), making it cold with a persistently gray sky.

In contrast, the average high temperature in July is 84°F (29°C), and the low is 62°F (17°C), leading to warm and humid summers. The annual precipitation is about 33 inches (838mm).

Snowfall is more than expected. The average annual snowfall is about 43 inches (approximately 109cm), and due to the lake effect from Lake Erie and Lake St. Clair, sudden heavy snowfalls can occur in winter.

From November to March, there are many cloudy days with frequent snowfall, allowing for the experience of Michigan's unique 'gray gloom' during winter. This long winter is often the most challenging aspect for those starting their lives in Detroit.

Spring usually arrives late. There are many chilly days even in April, and it isn't until May that the true spring atmosphere begins. While spring tends to be rainy, the greenery from May to early June is truly beautiful. Fall peaks in October, with stunning foliage throughout Metro Detroit. Some people even visit Michigan for a 'leaf-peeping drive' like they do in Milwaukee or Chicago.

Summer is the season that Detroit residents look forward to the most.

It is warm and humid, but great for outdoor activities, and the Detroit Tigers' home games add to the summer experience.

Thunderstorms accompanied by lightning can occur until September, which is also part of Michigan's summer landscape. Overall, the seasonal pattern is similar to that of Korea, but the most significant difference is that winter is longer and harsher.
