For the summer months (June-August), when average temperatures stay around 27-28°C and maximums can exceed 31°C, be sure to pack light, breathable clothing: cotton t-shirts, shorts, sundresses, and sandals. Even though the total amount of rainfall is small, summer is the period with the most rainy days (up to 24 in July), so a light raincoat or compact umbrella will come in very handy. Don't forget sunscreen, a hat, and sunglasses, as the sun is quite strong here.

During the shoulder seasons—spring (March-May) and autumn (September-November)—the weather in Biloxi is very comfortable but changeable. Average temperatures in spring range from 17°C to 24°C, and in autumn from 26°C down to 16°C. Layering is ideal during this time: t-shirts, light sweaters or cardigans, and jeans or trousers. A light jacket or windbreaker will be useful for evening walks or cooler days. Winter (December-February) is mild here, with average temperatures of 11-15°C. You will need warmer items: sweaters, a fleece jacket, a mid-season jacket, and closed-toe shoes. While there are no severe frosts, a light scarf and gloves can add comfort on windy days.

Regardless of the season, comfortable walking shoes are an absolute necessity, as Biloxi is a great city for exploring on foot. Given its coastal location, a light windbreaker can be useful year-round, especially during cooler times of day or when there is a breeze from the Gulf of Mexico. Also, remember a power adapter if you are traveling from a country with different plug standards, and a portable charger for your gadgets.
