Climate - Florida's weather is dominated by the water that surrounds it. The Atlantic Ocean in the east and the Gulf of Mexico in the west provide a stabilizing force that maintains the mild climate. Northern Florida is considered sub tropical, although it does receive some snow. This area is drier than the rest of the state. Southern areas of the state, definitely the Keys, lie within a tropical climate. Humidity is high, a characteristic of the climate, although the temperatures usually don't extend past 90 degrees F.
On the average the state receives 50 to 65 inches of rain. Summer is the rainy season, which extends into October in the south. Hurricane season begins in late August. Some hurricanes can bring up to 25 inches of rain. An average of two hurricanes per season reach the Florida peninsula. Most often these storms reach the Atlantic Coast rather than the Gulf Coast
The main entrance, and marked nature trail at Dagny Johnson Key Largo Hammock Botanical State Park, is located on Monroe County Road 905, approximately one-half mile north of CR 905's intersection with US Highway 1 at Mile Marker 106.
