Jacksonville is located in northeastern Florida, making it less tropical than Miami or Tampa, but the climate is still quite warm.

According to the Köppen climate classification, it falls under the humid subtropical climate (Cfa), characterized by long, hot, and humid summers and mild winters. Let's take a closer look at Jacksonville's weather with specific figures.

In terms of temperature, the average annual temperature is about 20°C (68°F). During the summer months (June to August), the average high temperature reaches 33-35°C (91-95°F), and with high humidity, the perceived temperature is even higher. July is the hottest month of the year. In winter (December to February), the average high temperature is around 18-20°C (64-68°F), which is cool, but it rarely gets cold enough for ice to form or snow to accumulate.

January is the coldest month, with nighttime temperatures sometimes dropping below 5°C (41°F). Although it's Florida, Jacksonville can occasionally experience temperatures below freezing, unlike southern Florida. Spring (March to May) and fall (September to November) have moderate and pleasant temperatures, making them the best times for outdoor activities.

The annual rainfall is about 1,300mm (52 inches), which is above the national average. Rainfall is concentrated in the summer. During the rainy season from June to September, showers or thunderstorms occur almost every afternoon.

This is due to the convective phenomena in the interior of the Florida peninsula, where rain often falls briefly and heavily. Winter is relatively dry. Because there is a distinct rainy season, scheduling outdoor events without considering the summer rains can lead to disappointment. The pattern of finishing outdoor activities in the morning and avoiding afternoon thunderstorms is a fundamental part of summer life in Jacksonville.

Snowfall is almost nonexistent. It is a rare occurrence for Jacksonville to see snow, happening perhaps once in several decades. In January 2023, Jacksonville made news for experiencing an unusual snowfall. The annual sunshine hours are about 2,850 to 3,000 hours, which is abundant.

This significantly exceeds the national average, which is why Florida is nicknamed "The Sunshine State."

When considering a move to Florida, the weather is often cited as one of the biggest advantages.
