Atlanta, located in the United States, is characterised by a humid subtropical climate. This means the city experiences four distinct seasons: hot, humid summers and mild, cool winters. Thanks to this climate, extreme weather conditions are rare here, making Atlanta an attractive destination to visit at various times of the year.

The summer months, from June to August, are quite hot in Atlanta, with average temperatures hovering around 25-26°C, and maximums often exceeding 30°C. This period also sees the highest number of days with precipitation, although the total amount of rainfall in millimetres, according to the provided data, remains low. Winters (December-February) are mild, with average temperatures from 7°C to 10°C, and while cold snaps are possible, severe frosts are atypical. Spring (March-May) and autumn (September-November) offer the most comfortable weather with pleasant temperatures, ideal for exploring the city.

Despite the low total volume of rainfall in millimetres, it is distributed relatively evenly throughout the year in Atlanta. However, the number of rainy days varies significantly, peaking during the summer months. This suggests that while rains may be frequent in summer, they are likely short-lived. Overall, Atlanta's climate allows for trip planning in almost any season, but the spring and autumn months are often considered the most favourable due to moderate temperatures and fewer rainy days compared to the peak of summer.

The climate in Atlanta is characterised by noticeable seasonal temperature changes throughout the year. The hottest months are traditionally July and August. In July, the average temperature is 26.4°C, with daytime highs often reaching and exceeding 30.8°C. August is not far behind, with an average temperature of 26.0°C and maximums around 30.3°C. The coolest month of the year is January, when the average temperature holds at 7.2°C, and average nightly lows can drop to 2.6°C.

The summer period in Atlanta, from June to August, can be described as hot and quite humid. Average maximum air temperatures during these months range from 29.5°C in June to 30.8°C in July, creating a truly summery atmosphere. Winters, conversely, are mild and cool. From December to February, average temperatures vary from 7.2°C in January to 10.9°C in February. Although night frosts are possible, especially in January (average low 2.6°C), severe and prolonged freezes are not typical for Atlanta.

Throughout the year, Atlanta experiences perceptible diurnal temperature fluctuations. The difference between average daytime highs and nightly lows is often around 8-10°C. This means that even in the height of summer, evenings can bring refreshing coolness, while in winter, the daytime sun can noticeably warm the air after a colder night. The spring (March-May) and autumn (September-November) months offer the most comfortable and moderate temperatures, smoothly transitioning the city from winter cool to summer heat and back.

In Atlanta, precipitation is distributed throughout the year, but its character and frequency change noticeably depending on the season. Although the total amount of rainfall in millimetres does not show sharp fluctuations from month to month, varying on average from 3 to 5 mm, the number of days with precipitation undergoes more significant changes. This means that in some periods rains may be more frequent, but not necessarily heavier.

The highest frequency of precipitation is observed in the summer months. July stands out as the month with the highest number of rainy days — on average 18 days, followed by August (16 days) and June (14 days). At the same time, the average monthly rainfall in these months is about 4 mm, which may indicate frequent but likely short-lived showers characteristic of hot and humid summers. Regarding the highest volume of precipitation, February and March lead with a figure of 5 mm per month, with 12 rainy days counted in each of these months as well.

The periods with the least amount of rainfall and rainy days fall in autumn and late spring. October is the "driest" month both in terms of rainfall amount (3 mm) and the number of rainy days (only 7). In November, the amount of rainfall (3 mm) is the same as in October, while the number of rainy days (8) is slightly higher than in October (7). May also belongs to the months with lower rainfall volume (3 mm), although there are about 11 rainy days in this month. In general, Atlanta does not have a pronounced prolonged rainy season or long drought, but it is worth being prepared for precipitation, especially during the summer period.

When packing your suitcase for a trip to Atlanta, it is important to consider its humid subtropical climate with distinct seasons. Regardless of the time of year, comfortable shoes for walking around the city and a light umbrella or raincoat will become your faithful companions. Although the total rainfall in millimetres is small, rainy days happen regularly, especially in summer (June-August), when their number can reach 14-18 per month. For the summer months, when the average maximum temperature rises above 30°C, pack light, breathable clothing made of natural fabrics, shorts, t-shirts, and don't forget sunscreen, sunglasses, and a hat for protection against the strong southern sun.

In winter (December-February) in Atlanta, although it is mild, the temperature can drop to 2-6°C, especially in January. Therefore, your luggage should include warm clothes: sweaters, a fleece jacket, and a medium-weight jacket. A scarf, hat, and gloves will also not be amiss for comfortable walks. In spring (March-May) and autumn (September-November), the weather is most changeable and pleasant, so the principle of layering in clothing will be very handy. Light sweaters, long and short-sleeved t-shirts, jeans or trousers, as well as a light jacket or windbreaker will allow you to easily adapt to temperature changes throughout the day. Even in relatively dry October, when there are only about 7 rainy days, a small umbrella won't hurt.
