Good evening, everyone, and Happy Fourth of July! If you’re planning to spend the holiday outdoors, the weather will be very typical for early July here in Jacksonville. We’ll start the morning with a mix of sunshine and a few clouds, along with warm and muggy conditions. Temperatures will climb quickly through the morning, reaching the lower 90s by the afternoon, but when you factor in the humidity, it will feel more like the upper 90s to near 100 degrees. If you’re heading to the beach, a barbecue, or one of the many community celebrations, be sure to stay hydrated, take frequent breaks in the shade, and don’t forget the sunscreen.
As we move into the afternoon, the combination of daytime heating and abundant moisture will lead to scattered showers and thunderstorms developing across the area. Not everyone will see rain, but any storm that forms could produce brief heavy downpours, gusty winds, frequent lightning, and reduced visibility. These storms will be hit-or-miss, meaning some neighborhoods stay completely dry while others experience a quick but intense thunderstorm. If thunder roars, head indoors until the storm passes.
Looking ahead to the evening, many of those afternoon storms should gradually weaken as the sun goes down, allowing conditions to improve for many Fourth of July festivities and fireworks displays. However, there’s still the possibility that a few isolated showers or storms could linger into the early evening, so if you’re attending a fireworks show, it’s a good idea to check the latest radar before heading out and have a rain plan just in case.
Boaters should also be prepared for rapidly changing weather on the water, as thunderstorms can produce sudden gusty winds and dangerous cloud-to-water lightning. Beachgoers should remain alert for changing conditions as well, especially if storms begin to develop nearby.
Overall, expect a hot, humid Independence Day with afternoon temperatures around 93 degrees, heat index values approaching 100 degrees, and scattered afternoon thunderstorms before improving conditions for much of the evening. While Mother Nature may interrupt a few outdoor plans for a short time, many locations should still have a good opportunity to enjoy fireworks later in the evening. Have a safe, enjoyable, and happy Fourth of July!
