Summertime is fun in Jacksonville, when visitors flock to the lakes, rivers, and beaches, and highs climb over 90°F. Jax’s far-north location means that it rarely gets hit by hurricane season (expect some summer thunderstorms nonetheless), and it’s still hot enough to hit the beach through spring and early fall. In winter, the mild weather and diminishing crowds can be a bonus for campers, but don’t expect the balmy temperatures of the south.
