Summer Showers and Storms Sweep Jacksonville: What to Expect!

Jacksonville, FL, USA - As the clock ticks on June 11, 2025, Jacksonville finds itself under a familiar summer weather pattern, with sea breezes triggering scattered showers and thunderstorms across the region. The current conditions are bringing an unpredictable mix of sun and storms—a classic hallmark of Northeast Florida’s humid summers. Earlier storm activity was reported notably in Putnam, Flagler, and St. Johns counties, highlighting the capricious nature of our summer weather.

The weather forecast for today shows areas along the sea breeze and the River being particularly susceptible to storm formation. Local residents can expect the heat to fuel this stormy demeanor, with the main hazards being locally heavy rainfall and strong winds. With temperatures hovering just above seasonal averages, the humidity is making the low 90s feel more like sweltering triple digits.

What’s on the Horizon?

Looking ahead to the evening, showers and thunderstorms are poised to continue, followed by clearing skies that could lead to patchy to dense fog late at night. Tomorrow’s forecast? Hot and humid, with southeasterly winds expected to keep things steamy, presenting a 40-70% chance of afternoon storms and locally heavy rain.

The temperature will dip into the low 70s at night but soar into the 90s during the day, particularly inland. Along the beaches, temperatures will linger in the upper 80s to low 90s range—a perfect excuse for a late-afternoon dip or a stroll along the shoreline. Winds will be gentle at 10-15 mph from the southeast, a refreshing breeze that complements the summer heat.
