St. Augustine is old. Like, 1565 old. When you walk down St. George Street, you’re stepping on layers of history that have survived fires, pirate raids, and, most consistently, hurricanes St. Augustine Florida has weathered for nearly five centuries. But here’s the thing—if you listen to the national news during storm season, you’d think the "Ancient City" is underwater every other Tuesday. It’s not. But it’s also not perfectly safe, and the nuance is what actually matters if you’re planning a trip or looking at real estate near the Matanzas River.
People obsess over the "big one."
Honestly, the big one hasn't really happened in the way people fear since 1964. That was Hurricane Dora. It was a direct hit, a rarity for this stretch of the Atlantic coast. Since then, we've mostly dealt with "brush-bys" that feel like the end of the world because of one specific problem: flooding. St. Augustine isn't just a coastal town; it’s a marshy peninsula. When the tide is high and the wind pushes the Atlantic into the Matanzas, the water has nowhere to go but up into the streets of Davis Shores.
The Geography of Risk in the Ancient City
You have to understand the layout.
St. Augustine is tucked behind barrier islands—Anastasia Island and Vilano Beach. These strips of sand take the brunt of the ocean's rage. When a hurricane or a nasty Nor’easter rolls through, the dunes on Anastasia State Park act like a shield. But shields break. During Hurricane Irma in 2017 and Hurricane Ian in 2022, the surge didn't just come from the ocean; it backed up through the inlets and the Intracoastal Waterway. It’s a literal pincer move by the water.
Is the city sinking? No. Is it getting wetter? Absolutely.
The City of St. Augustine has been dumping millions into backflow preventers and massive pump stations, particularly near the Lake Maria Sanchez neighborhood. If you're visiting and you see a sunny day but there's a foot of water on South Castillo Drive near the Castillo de San Marcos, that’s "nuisance flooding." It’s a byproduct of sea-level rise and the city's precarious elevation. It doesn't even take a hurricane to make the city look like Venice; sometimes a particularly aggressive full moon tide does the trick.
Matthew, Irma, and Ian: The Triple Threat
Let's look at the recent track record because it’s weird. For decades, St. Augustine was famously "lucky." Then 2016 happened.

Hurricane Matthew stayed offshore, but its eyewall scraped the coast. It gutted the A1A in Summer Haven and sent four feet of water into the downtown Bayfront. Then, barely a year later, Irma showed up. Irma wasn't even an East Coast storm; it went up the Gulf side, yet the surge in St. Augustine was nearly as bad because of the storm's massive wind field.
Then came Ian in 2022. Ian was a nightmare for Fort Myers, but by the time it reached Northeast Florida, it was a tropical storm. Still, it caused record-breaking flooding. Why? Because the ground was already soaked and the dunes were already weakened.
- Matthew (2016): Wind damage and massive dune erosion.
- Irma (2017): Massive river flooding and sewage overflows.
- Ian (2022): Unprecedented surge in areas that historically stayed dry.
- Nicole (2022): Took out what was left of the Vilano and A1A coastal structures.
Why the "Hurricane Hole" Myth Still Persists
There’s this old legend that the Timucua Indians blessed this land to be protected from storms. Some locals swear by it. They point to the fact that the city has survived 450+ years as proof. While it’s true that the "elbow" of the Florida coastline—where the state tucks inward toward Georgia—naturally deflects many tracks coming from the south, it’s a dangerous game to rely on ancient blessings.
Modern meteorology tells a different story.
The National Hurricane Center (NHC) notes that the North Atlantic oscillation and the Gulf Stream's proximity make the waters off St. Augustine a highway for storms. Most of the time, they curve north or stay far enough out to only give us a "dirty side" lashing (heavy rain and wind). But "most of the time" isn't "always." The 1894 storm and the 1964 Dora are the historical reminders that the "blessing" has an expiration date.
What it’s Actually Like During a Storm
Living through a hurricane in St. Augustine is mostly just loud. And humid.
The power usually goes out early. If you live on the island, the bridges (Bridge of Lions and the Mickler Bridge) close once sustained winds hit 40 mph. You’re stuck. Either you're stuck on the island with the crashing surf, or you're stuck on the mainland watching the river rise. The sound of the wind through the live oaks is a low-frequency roar you never quite forget.

And the smell. After a surge, the city smells like placo (marsh mud) and salt. It's a heavy, organic scent that lingers for weeks while people drag sodden drywall to the curb.
The Resilience of Coquina
There is a silver lining. The Spanish knew what they were doing when they built the Castillo de San Marcos out of coquina. This "shell stone" is essentially ancient Styrofoam. When a cannonball—or a piece of hurricane debris—hits it, the stone doesn't shatter. It compresses. It absorbs the blow.
Many of the oldest buildings in the historic district use similar materials or tabby (a mix of lime, sand, and shells). These structures have outlasted every modern "hurricane-proof" condo. There’s a lesson there about building with the environment instead of trying to fight it.
Practical Realities for Travelers and Newcomers
If you’re planning a trip between June and November, you need to be smart. Don’t just look at the sky.
- Check the Tide Tables. A Category 1 hurricane hitting at low tide is a nuisance. A Tropical Storm hitting at high tide is a catastrophe for downtown businesses.
- Understand Zone A. Almost the entire historic district and Anastasia Island are in Evacuation Zone A. If the county says go, you go. The bridges will close, and emergency services won't come across them until the winds die down.
- The "Post-Storm" Vacation. If you have a trip booked for the week after a storm, don't necessarily cancel. St. Augustine is a tourism-dependent economy. After Hurricane Ian, the city was "open for business" within days, even while owners were still drying out their basements. They need your business more than ever after a hit.
Insurance is the other elephant in the room. If you’re buying property, the "hurricane tax" is real. Flood insurance premiums in 32080 and 32084 zip codes have skyrocketed. We’re talking about houses that used to cost $800 a year to insure now costing $4,000 or more, thanks to FEMA's Risk Rating 2.0.
The Weird Side of the Weather
Hurricanes bring some strange things to our shores. After Matthew, the beaches were littered with "sea beans"—tropical seeds that floated all the way from the Caribbean. We also get "hurricane birds," rare pelagic species like Sooty Terns that get trapped in the eye and dumped off in the marsh when the storm dissipates.
It’s a reminder that these storms are massive biological transporters, not just destructive engines. They reshuffle the dunes, flush out the lagoons, and—honestly—keep the city from getting too crowded. The threat of hurricanes is the price of admission for living in the most beautiful city in Florida.

How to Stay Informed (The Local Way)
Stop watching the national weather channels for local specifics. They want ratings; you want the truth.
Follow the St. Johns County Emergency Management Facebook page or website. They are the ones who make the calls on bridge closures and evacuations. Also, keep an eye on "Mike's Weather Page" (spaghettimodels.com). It looks like a website from 1998, but it's what every local uses to track the real data.
Actionable Steps for Storm Season
If you find yourself in St. Augustine when a "cone of uncertainty" is pointing at the Matanzas Inlet, here is exactly what you do. First, move your car. If you are parked anywhere near the bayfront or the downtown side streets, get your vehicle to the parking garage on West Castillo Drive. It’s one of the highest points in the immediate area.
Second, stock up on water, but skip the plastic bottles if you can. Fill your bathtub. St. Augustine’s water system is old, and a major power outage can lead to boil water notices. Third, if you're a tourist, check with your hotel about their generator status. Places like the Casa Monica have robust systems, but smaller B&Bs might leave you in the dark (literally).
Final thought: Don't fear the storm, but respect the water. The wind will blow your shingles off, but the water will take your whole house. In St. Augustine, the water is always looking for a way back in.
Next Steps for Safety:
- Download the SJC Connect app for real-time local emergency alerts.
- Identify your evacuation zone via the St. Johns County GIS maps before hurricane season begins.
- If you own property, install "smart" vents in your crawlspace to allow surge water to flow through rather than knocking the structure off its foundation.
- Keep a physical map of the backroads (like SR-13 and US-1) because I-95 becomes a parking lot during a mandatory evacuation.
