St. Augustine Weather Overview

St. Augustine sits on Florida's northeast Atlantic coast, 40 miles south of Jacksonville, where a humid subtropical climate delivers hot, wet summers and mild, dry winters. The low latitude and direct ocean exposure make the city uniquely vulnerable to coastal hazards — sea breezes, tidal flooding along the Matanzas River, and the full range of tropical weather during hurricane season. Use the St. Augustine weather radar to track incoming storms and coastal flood conditions in real time.

Hurricanes are the highest-stakes threat. Hurricane Dora (1964) was the last major hurricane to score a direct hit on St. Augustine. More recently, Hurricane Matthew (2016) passed just east of the city but triggered catastrophic flooding in the historic downtown, a reminder that even near-miss storms can overwhelm the low-lying waterfront. Hurricane season runs June 1 through November 30, with peak activity from mid-August through October. The NWS Jacksonville office (WFO JAX) monitors the entire First Coast region for tropical development and issues warnings when systems approach.

Beyond hurricane season, St. Augustine averages roughly 52 inches of rain per year, most of it falling as intense afternoon thunderstorms from May through September. Summer heat indices regularly exceed 100°F. Winters are generally mild, but Arctic intrusions occasionally push temperatures below freezing — the record low of 10°F was set on January 21, 1985. Spring can bring near-drought conditions and wildland fire risk in St. Johns County. Keep the St. Augustine weather radar bookmarked for fast access to live doppler data year-round.

St. Augustine Weather Risks & Safety

Key weather hazards to monitor on the St. Augustine weather radar

Hurricane & Tropical Storm Risk

St. Augustine sits in the path of Atlantic and Gulf tropical systems. Hurricane season runs June 1 through November 30, peaking in August and September when warm sea surface temperatures fuel rapid intensification. On the radar, you can track the eye wall, rain bands, and embedded tornadoes as a storm approaches. If you live in St. Augustine, keep your evacuation plan current and check the radar frequently once a tropical advisory is issued.

Flooding & Flash Flood Risk

Flash flooding is St. Augustine's most persistent weather hazard. Slow-moving thunderstorms or tropical moisture can dump enough rain to overwhelm drainage systems within hours — especially in paved urban areas where water has nowhere to go. Check the radar to see where the heaviest rain is falling and which areas to avoid. The standing rule: turn around, don't drown. Never drive through flooded roads, even if they look shallow.

Severe Thunderstorm Risk

Severe thunderstorms roll through St. Augustine regularly, especially spring through early fall. Expect damaging winds above 58 mph, large hail, and dangerous lightning. The radar shows you each storm cell's position, movement, and intensity — so you can tell if one is headed your way. When a thunderstorm warning drops for St. Augustine, get indoors and away from windows until it passes.

How to Use St. Augustine Weather Radar

Follow these steps to get the most from the St. Augustine weather radar data.

Check Current Conditions

Look at the weather status bar at the top of the St. Augustine radar page — it shows temperature, humidity, wind speed, and current conditions at a glance, including any active coastal flood advisories.

Watch the Radar Map

The radar map shows precipitation moving across St. Augustine and St. Johns County. Toggle between precipitation and cloud cover, then play the animation to see which direction storms are tracking along the coast.

Check the Forecast

Scroll down to the hourly and 7-day forecast. During hurricane season (June–November), check for any tropical activity in the western Atlantic or Gulf that could affect the First Coast.

Decide What to Do

If a hurricane watch or flood warning is issued for St. Augustine, check back frequently — storm surge and coastal flooding can escalate quickly along the low-lying Matanzas River waterfront.

St. Augustine Weather FAQ

Common questions about St. Augustine weather patterns and radar

When is hurricane season in St. Augustine?

Hurricane season runs June 1 through November 30, with peak activity from mid-August through October. St. Augustine's Atlantic coastal position makes it vulnerable to both Gulf and Atlantic tropical systems. The last direct major hurricane hit was Hurricane Dora in 1964. Hurricane Matthew (2016) caused widespread downtown flooding even while tracking just offshore.

How much rain does St. Augustine get each year?

St. Augustine receives approximately 52 inches of rainfall per year. The wet season runs May through September, driven by daily convective thunderstorms fueled by Gulf and Atlantic moisture. The dry season from November through April can bring near-drought conditions, occasional wildland fire risk, and long stretches of sunny weather across St. Johns County.

Does St. Augustine flood during hurricanes?

Yes. The historic downtown sits just feet above sea level along the Matanzas River, making storm surge and coastal flooding a serious risk. Hurricane Matthew (2016) caused catastrophic downtown flooding with waters reaching several feet into street level. Any hurricane or strong tropical storm passing nearby can push ocean water into the city's low-lying waterfront areas.

What is the record low temperature in St. Augustine?

The record low is 10°F (−12°C), recorded on January 21, 1985. St. Augustine averages just 4.6 frost events per year. Most winters bring mild, dry conditions with daily highs in the upper 60s°F. When Arctic cold fronts do penetrate northeast Florida, temperatures can drop sharply overnight, catching unprepared residents off guard.

How is this different from First Coast News or WOKV St. Augustine radar?

First Coast News and local Jacksonville stations provide radar alongside live meteorologist coverage during active storm events — valuable for detailed storm analysis. This page offers a lightweight, ad-free alternative built around interactive RainViewer radar maps, Open-Meteo hourly forecasts, and a 7-day outlook specifically for St. Augustine. Radar imagery updates approximately every 10 minutes.

What are the biggest weather risks in St. Augustine, Florida?

The top threats are hurricanes and tropical storm surge, coastal and inland flooding, and severe afternoon thunderstorms from May through September. The city's elevation near sea level and position on the Atlantic coast amplify both flooding and wind risks. Secondary threats include rare winter freezes and spring wildland fire danger during drought periods in St. Johns County.
