Notes
How bad is hurricane risk in St. Johns County?
This is Atlantic Florida: hurricane season runs June through November, and storm surge and flooding matter as much as wind. Risk is not uniform. A well-built inland house west of the Intracoastal and a dune-front condo are different products that share a county name.

Atlantic hurricane season, as defined by the National Hurricane Center, runs from June 1 through November 30. St. Johns County is on the ocean. That is the whole first paragraph, and it should be enough to take preparedness seriously. It is not enough to treat every listing as equally exposed.
Wind is what people picture. Water is what rearranges neighborhoods. Storm surge and rainfall flooding follow elevation, marshes, the Intracoastal, the San Sebastian, and the St. Johns River as much as they follow a storm’s category label. The county’s emergency management office maps evacuation zones A through F. Zone A covers the most low-lying coastal and river edges; later letters generally step inland and up. Zone F is called out along the St. Johns River. Look up a specific address on the county’s evacuation guidance and, separately, on a FEMA flood map. A marketing phrase like “close to the water” is not a zone.
Historic St. Augustine and the beaches have flooded in king-tide weeks and named storms; inland villages are not automatically dry. Ponds, new grading, and poorly drained lots can pond water after ordinary summer rain. Ask about elevation certificates, finished-floor height, and what the street did in the last wet season — not only what the March photos show.
Building codes and roof age matter for wind. Newer construction is generally designed to a more recent Florida code than a 1980s cottage. That does not make a new house surge-proof. It does change the insurance and mitigation conversation. Look at roof year, opening protection, and whether a wind-mitigation inspection already exists before you negotiate.
Preparedness is a household skill here: a plan for pets, a sense of where you would go if your zone is called, and documents you can actually find. Mobile-home residents should treat evacuation orders as non-optional regardless of the letter on a nearby house. Officials urge people with a safer inland option — a friend, a hotel, family — to use it rather than waiting for a public shelter as the first idea.
We would not tell you this county is uniquely doomed, and we would not tell you it is a storm-free suburb that happens to have beaches. It is Florida’s northeast coast. Buy the house like you understand water. Then enjoy the ordinary Tuesdays, which are most of them. More on coverage is in our note on insurance.
