Hurricane and Storm Risk in Westport, CT: Two Ways the Water Comes In
Westport sits on Connecticut's Fairfield County "Gold Coast," a 33.45-square-mile town (19.96 square miles of land, 13.49 of water) that Long Island Sound touches directly and that the Saugatuck River cuts straight through on its way to that same Sound. That geography is the reason storm risk here is not one thing but two: a coastal-surge threat along Compo, Saugatuck Shores, and the rest of the shoreline when the Sound itself pushes inland, and a separate river-flooding threat downtown when the Saugatuck River overflows its banks along Riverside Avenue. A single hurricane or major storm can trigger either mechanism, both at once, or neither, depending on rainfall totals, the storm's track, and where its worst winds line up with the tide. This page walks through both mechanisms using Westport's own documented storm history -- Hurricane Sandy in 2012, Hurricane Gloria in 1985, the floodplain breaches of 1992 and 1996, and recent non-hurricane storm events in January 2024 and July 2026 -- rather than generic hurricane-preparedness filler.
Two Mechanisms, Not One: Sound Surge and Saugatuck River Overflow
The single most important thing to understand about storm risk in Westport is that it is not a single, uniform hazard spread evenly across town. The first mechanism is coastal storm surge off Long Island Sound itself, which bears most directly on shoreline neighborhoods such as Compo and Saugatuck Shores and other areas that front the Sound. The second mechanism is the Saugatuck River overflowing its banks well inland from the shoreline, which bears most directly on downtown Westport and Riverside Avenue, where the river runs closest to commercial and civic buildings.
Those two mechanisms do not always move together. A storm that dumps heavy rainfall inland can push the Saugatuck River over its banks downtown even without a significant coastal surge, while a storm whose worst surge arrives at high tide can flood the Compo and Saugatuck Shores shoreline without necessarily overwhelming the river. A major hurricane can also do both at once, as Sandy demonstrated in 2012. Anyone evaluating flood exposure in Westport should ask which of these two mechanisms -- or both -- applies to a specific address, rather than treating "storm risk" as one uniform figure for the whole town.
Hurricane Sandy, 2012: The Town’s Own FEMA Numbers
Hurricane Sandy struck the East Coast in late October and early November 2012, and Westport's own town-produced FEMA report, as reported by Patch, put real numbers on what it did locally: 7 homes destroyed, 260 homes flooded, and 25 homes affected by tree damage. Power outages peaked at 86% of the town without power on October 31, representing roughly 10,639 CL&P customers. Schools and Town Hall closed during the storm.
The town's response reflected the scale of the damage: the entire Westport shoreline was closed, with police barriers set up at multiple access points, and evacuated residents were not permitted to return home until floodwaters had receded. Sandy is the clearest documented case of Westport's coastal-surge mechanism and its inland flooding effects arriving together, and the destroyed-homes and flooded-homes figures above come directly from the town's own FEMA reporting, not from a generic regional damage estimate.
Hurricane Gloria, 1985, and the Floodplain Breaches of 1992 and 1996
Sandy was not Westport's first serious storm. Hurricane Gloria struck in 1985, and the Fairfield Museum's own storm-history exhibit describes it as causing heavy damage to homes and businesses along the shore, particularly between Westport and Milford -- a regional description that places Westport squarely inside the damage zone rather than at its edge.
Separately from named hurricanes, Westport's floodplain itself has been breached on documented occasions outside of any specific storm name: in 1992 and again in 1996, breaches caused damage to private property, including the train station parking lot. Today, about 26% of Westport residents live within the 100-year floodplain, a figure worth sitting with regardless of any single storm's forecast, since it describes a standing structural exposure rather than a one-time event.
Recent Storms That Were Not Hurricanes: January 2024 and July 2026
Westport's storm risk is not limited to named hurricanes. On January 13, 2024, the town experienced its third significant weather event in a single week: over 1 inch of rain fell alongside 50 to 60 mph wind gusts overnight, and the Saugatuck River overflowed its banks downtown and along Riverside Avenue, with low-lying coastal and shoreline areas flooding at the same time. That event is a clean, recent illustration of both mechanisms described above showing up together in a storm well short of hurricane strength.
More recently, on July 21, 2026, nearly 550 Eversource customers lost power, with outages concentrated west of the Saugatuck River. A large tree fell on Kings Highway and damaged power lines, and flash flooding stranded at least one vehicle near downtown. Neither of these two events was a hurricane, and neither should be read as one -- they are included here because they show the same two risk mechanisms recurring in ordinary severe-weather events, not only in major named storms.
What This Page Does Not Know, and Where to Get It
This page does not have, and does not invent, a Westport-specific account of the 1938 Great New England Hurricane's local impact. That storm is well documented for Connecticut as a whole, but no Westport-specific narrative was confirmed, so none is stated here. This page also does not have current wind-speed forecasts, storm-surge-height estimates, NOAA or National Hurricane Center risk-category data specific to Westport, or a current hurricane-evacuation-zone designation for the town, and none of those figures is invented here either.
For current storm tracking and forecasts, go directly to NOAA and the National Hurricane Center. For Westport-specific evacuation guidance, shelter information, and emergency alerts, go directly to Westport's own emergency management office rather than relying on any evacuation-zone figure that is not stated on this page. For flood-zone determinations on a specific parcel, use FEMA's Flood Map Service Center, and see this market's flood-zones page for more on that topic.
What This Means If You Are Evaluating a Westport Property
The honest picture is that Westport carries two distinct, documented storm-risk mechanisms rather than one: Long Island Sound coastal surge affecting Compo, Saugatuck Shores, and other shoreline areas, and the Saugatuck River overflowing its banks downtown along Riverside Avenue. Hurricane Sandy in 2012 showed both mechanisms at their worst in the same event, Hurricane Gloria in 1985 and the 1992 and 1996 floodplain breaches show the pattern is not a single-storm fluke, and the January 2024 and July 2026 events show it recurring in ordinary severe weather, not only in named hurricanes.
A property's actual exposure depends heavily on which mechanism, or mechanisms, apply to its specific location -- a Compo or Saugatuck Shores address and a downtown Riverside Avenue address face genuinely different versions of this risk. Get a flood-zone determination for the specific parcel from FEMA's Flood Map Service Center, ask Westport's emergency management office about current evacuation guidance, and check NOAA and the National Hurricane Center for current storm tracking before making a purchase, insurance, or emergency-planning decision. Nothing on this page is emergency-planning, insurance, or financial advice.

Hurricane Sandy (2012) figures -- 7 homes destroyed, 260 homes flooded, 25 homes affected by tree damage, 86% of the town without power at peak on October 31 (roughly 10,639 CL&P customers), school and Town Hall closures, the shoreline closure with police barriers, and the delayed return of evacuated residents -- come from Westport's own town-produced FEMA report, as reported by Patch. Hurricane Gloria's (1985) shoreline damage description, "particularly between Westport and Milford," comes from the Fairfield Museum's own storm-history exhibit. The 1992 and 1996 floodplain breaches, the train-station-parking-lot damage, and the figure that about 26% of Westport residents live within the 100-year floodplain are drawn from local flood-history reporting. The January 13, 2024 event (third significant weather event in one week, over 1 inch of rain, 50-60 mph wind gusts, the Saugatuck River overflowing its banks downtown and along Riverside Avenue, and coincident coastal flooding) and the July 21, 2026 event (nearly 550 Eversource customers without power concentrated west of the Saugatuck River, a fallen tree damaging power lines on Kings Highway, and flash flooding stranding a vehicle near downtown) are drawn from local news reporting on those dates. Town geography figures (33.45 square miles total, 19.96 land, 13.49 water; Fairfield County; the Long Island Sound "Gold Coast" description; the Saugatuck River bisecting the town) are standard geographic reference data. This page does not state, and does not invent, a Westport-specific account of the 1938 Great New England Hurricane's local impact, any current wind-speed or storm-surge-height figures, any current NOAA or National Hurricane Center risk-category data for Westport, or any current hurricane-evacuation-zone designation for the town -- all of these were not confirmed and are disclosed rather than invented. For current storm tracking, consult NOAA and the National Hurricane Center directly; for evacuation guidance and emergency alerts specific to Westport, consult the town's own emergency management office; for flood-zone determinations on a specific parcel, use FEMA's Flood Map Service Center.
