The weather in Duluth, GA exhibits typical subtropical characteristics of the northern Georgia inland.

Compared to Seoul, summers are hotter and more humid, while winters are much milder. There are four seasons, but they are not as distinct as in Korea, with spring and fall being short and summer lasting a long time. One of the most surprising aspects for newcomers to Georgia is this climate.

Looking at the temperatures by season, in summer (June to September), the daytime highs reach 32 to 36 degrees Celsius, and with high humidity, the perceived temperature can exceed 40 degrees. The average high temperature in Duluth in July is about 33 degrees, and the average low is around 22 degrees, leading to frequent tropical nights. The weather becomes difficult to endure without air conditioning from early June to early October. Spring (March to May) is warm and pleasant, but there is a lot of pollen and relatively high precipitation. Fall (October to November) is very pleasant and features beautiful autumn foliage, making it one of the most enjoyable seasons in Duluth.

Winter (December to February) is the mildest period in Georgia's climate. The average high temperature in January is about 10 degrees, and the low is around 0 to 2 degrees, which is much warmer than winter in Korea. Days that drop below freezing are rare, and snowfall is very minimal, so those accustomed to winter weather in Korea can manage much more easily. However, there are times when temperatures can drop suddenly or ice storms occur, which can paralyze the entire state of Georgia, so one should not let their guard down even in winter.

The annual precipitation in Duluth is about 1,300 mm, which is similar to Seoul (about 1,400 mm), but the distribution is different. Georgia experiences concentrated rainfall in spring (March to May) and summer (July to September), with sudden thunderstorms often occurring in the afternoons during the summer.

It is common for the sky to be clear one moment and then heavy rain to pour down within 30 minutes, making it essential to check the weather app when planning outdoor activities. Snowfall is very low, averaging 1 to 5 cm per year. Even a small amount of snow can paralyze the roads, so Gwinnett County often closes schools and businesses early when it snows due to a lack of snow removal equipment and experience.

The best seasons to live in Duluth are October and November during the fall. With temperatures between 18 and 24 degrees, low humidity, and beautiful autumn foliage, this period provides the perfect environment for outdoor activities and outings. Newcomers are often advised to arrive in the fall to gradually adapt to the climate.

Weather apps like Weather.com or Weather Underground are known to predict the weather in the Duluth area relatively accurately, and it is also good to set up alerts for thunderstorms and tornado warnings.
