The summer months in Jacksonville – from June to August – are distinguished by hot and humid weather. Average daytime temperatures confidently stay above 30°C, and nights remain very warm, with temperatures rarely dropping below 23-24°C. Combined with high humidity, evidenced by the large number of rainy days during this period, the summer heat can feel quite intense. This is an ideal time for those who love a true southern summer and are not afraid of high temperatures.

Winter in Jacksonville, on the contrary, is mild and pleasant. December, January, and February bring significant cooling compared to the summer heat, but frost here is a great rarity. Average daytime temperatures in the winter months range from 18°C to 22°C, and night-time temperatures drop to 9-12°C. This is a comfortable time for walking and exploring the city without exhausting heat. Throughout the year, noticeable diurnal temperature fluctuations are observed: the difference between daytime maximums and night-time minimums averages 7-10°C, which is especially perceptible in the transitional seasons and winter, when mornings can be quite fresh, while days are pleasantly warm.

In Jacksonville, there is a fairly clear division of the year into wet and dry seasons when it comes to precipitation. Overall, the city receives a moderate amount of precipitation, predominantly in the form of rain, as temperatures even in winter remain high enough that snowfall is a great rarity here. The greatest amount of precipitation falls in the summer months, while the rest of the year is characterized by drier weather.

The rainy season in Jacksonville falls during the summer months, peaking in July and August. During these months, the highest amount of precipitation falls – on average 6 mm, and the number of rainy days reaches 24-25. June and September are also quite wet: in June about 5 mm of precipitation and 21 rainy days are recorded, and in September – 5 mm of precipitation and 18 rainy days. Summer rains are often intense but can be short-lived, characteristic of a subtropical climate.

A drier period covers autumn, winter, and spring. The driest months in terms of rainfall are January, February, March, April, October, November, and December, when only 2 mm of precipitation falls. At the same time, the number of days with precipitation in these months varies from 7 days in January and December to 10 days in October. This suggests that winter and autumn-spring precipitation is generally less abundant and may present as light rain or drizzle. May can be considered a transitional month, with an increase in precipitation to 3 mm and 12 rainy days, foreshadowing the onset of the wetter summer season.

When packing for Jacksonville, it is important to consider its humid subtropical climate with hot, humid summers and mild winters. Regardless of the time of year, comfortable shoes for walking will be your best companion. In summer, from June to August, when the average temperature stays around 27-28°C and the maximum can rise above 31°C, give preference to light, breathable clothing made from natural fabrics such as cotton or linen. Given that the summer months (especially July and August) account for the peak of precipitation (up to 6 mm) and the highest number of rainy days (21-25 days per month), a compact umbrella or a light raincoat will be very handy. Do not forget sunscreen, a hat, and sunglasses for protection against the active southern sun.

In winter, from December to February, the weather in Jacksonville remains mild, with average temperatures from 13.8°C to 17.1°C. However, evenings and nights can be quite cool, with minimum temperatures dropping to 9-12°C. At this time of year, the principle of layering in clothing is ideal: take t-shirts, long-sleeved shirts, a sweater or fleece jacket, as well as a light or mid-season jacket. Although the amount of precipitation is significantly lower in winter (about 2 mm per month), the presence of 7-8 rainy days suggests that a light waterproof jacket or the same umbrella might come in useful.

In spring (March-May) and autumn (September-October), the weather in Jacksonville is particularly pleasant for travel, but can also be changeable. Average temperatures are comfortable, but diurnal fluctuations can be perceptible. Layering in clothing will help out again: light sweaters, cardigans, or windbreakers will help adapt to changing conditions. September is still quite warm (average temperature 26.3°C), but is also one of the wettest autumn months with 18 rainy days and 5 mm of precipitation, so a raincoat will not be superfluous. In general, choose versatile and comfortable items that are easy to combine to enjoy your trip to Jacksonville in any weather.
