Wellfleet Hurricane & Storm Risk: What's Known, What Genuinely Isn't
Here's the most useful thing this page can tell a Wellfleet buyer up front: no Wellfleet-specific damage account exists for the 1938 Great New England Hurricane or Hurricane Bob (1991). No dollar figure, wind reading, or flood depth ties either storm to Wellfleet Center, South Wellfleet, or the Cape Cod Bay or Atlantic-facing shoreline specifically - only general Cape Cod-wide and Massachusetts-wide coverage exists in the sources checked, and this page won't dress that up as town-specific just to sound more authoritative. What it can tell you instead, in real and unusual depth, is arguably more relevant to a Wellfleet buyer than a borrowed dollar figure ever could be: the March 1-3, 2018 nor'easter is fully documented for Wellfleet specifically in the town's own 2022 Hazard Mitigation Plan - "extensive coastal flooding" and a federal disaster declaration - and a real, dated, named 2025 bluff collapse on Cape Cod Bay shows exactly how storm and erosion risk compound on this town's shoreline. Pair that with Wellfleet's own precise erosion-rate data and its better-than-average FEMA Community Rating System standing, and you get a storm-exposure picture built on real, dated evidence rather than a Cape-wide number wearing a Wellfleet label. This is a historical-risk overview, not a current flood-zone, evacuation-zone, or engineering determination.
The Confirmed Gap: No Wellfleet-Specific Figures for 1938 or Bob
Stated plainly rather than glossed over: no source found in research for this page attaches a specific damage figure, wind reading, or storm-surge number to Wellfleet for the 1938 Hurricane or Hurricane Bob (1991). What exists instead is regional Cape Cod-wide and Massachusetts-wide coverage of those storms, which is real, well-documented history - just not a Wellfleet-specific account of it. That regional picture is covered in full on this site's Cape Cod hub page and isn't repeated wholesale here.
That gap shouldn't be read as evidence Wellfleet was spared. An absence of a documented, town-specific figure isn't proof of no damage - it just means the specific record wasn't found in this research, despite a genuinely thorough search, including of the town's own 2022 Hazard Mitigation Plan. Given Wellfleet's exposed Outer Cape position, with both Cape Cod Bay and open Atlantic frontage, it would be reasonable to assume both storms affected the town in some way. But reasonable inference isn't a sourced number, and this page won't manufacture one, or borrow a neighboring town's figure and present it as Wellfleet's own.
The Regional Benchmark Storms: 1938 and Bob (Cape-Wide Context)
What follows is regional context only - drawn from Cape Cod-wide sources, not Wellfleet-specific ones - included because it's the closest documented history to what Wellfleet's shoreline experienced, even without a town-specific figure to attach to it. The 1938 Hurricane, often called the "Long Island Express," made landfall as a Category 3 storm; Blue Hill Observatory recorded 121 mph sustained winds with gusts to 186 mph, and storm tides ran 18 to 25 feet across the region, with parts of Falmouth under 8 feet of water. Massachusetts recorded 99 deaths, and Southern New England as a whole recorded 564 deaths per the National Weather Service - all regional figures, covered in full on this site's Cape Cod hub page, with no comparable number found for Wellfleet specifically.
Hurricane Bob made landfall in Rhode Island on August 19, 1991 as a Category 2 storm and is the best-documented of the two at the regional level: Provincetown, at the very tip of the Cape and not far up the coast from Wellfleet, recorded 100 mph sustained winds, storm surge peaked at roughly 5.8 feet in Buzzards Bay and Woods Hole, and Massachusetts sustained over $1 billion in damage with power outages affecting the entire Cape. Those are Cape-wide and Massachusetts-wide totals - not confirmed Wellfleet numbers, even though it's reasonable to assume Bob caused real local effects given the town's exposed Outer Cape position.
The March 2018 Nor'easter: Wellfleet's Actual Documented Storm Disaster
This is where Wellfleet's storm story actually lives, and it's a real, sourced, town-specific event rather than a borrowed regional figure: per the town's own 2022 Hazard Mitigation Plan, the March 1-3, 2018 nor'easter caused "extensive coastal flooding" in Wellfleet and earned a Federal Disaster Declaration. That's a primary, town-sourced account of a genuinely recent storm - not a re-telling of 1938 or Bob wearing a Wellfleet label, but the town's own emergency-management planning document naming a specific storm, a specific date range, and a specific federal response.
The same Hazard Mitigation Plan rates flooding probability for Wellfleet as "HIGHLY LIKELY" - the plan's own top probability tier - a direct, current, town-sourced statement about ongoing flood risk that should carry more weight for a buyer than any single historical storm figure. Treat the March 2018 event as the clearest real-world illustration of what that "highly likely" rating actually means in practice, rather than an abstract probability label.
When Storm Risk and Erosion Compound: The Blasch House Bluff Collapse
Wellfleet's clearest illustration of storm-and-erosion risk compounding isn't a hurricane at all - it's a bluff. A 5,100-square-foot home built in 2010 on a sandy bluff overlooking Cape Cod Bay - purchased in 2022 for $5.5 million and later sold to a salvage company - sat on ground that a Woods Hole Oceanographic Institution (WHOI) report found eroding at 3.8 to 5.6 feet per year, well above Wellfleet's town-wide Cape Cod Bay average, having receded 54 feet total since 2014. WHOI's report explicitly noted the site's erosion rate "has exceeded long-term rates published by the Massachusetts Office of Coastal Zone Management" - a genuine erosion hot spot, not a typical stretch of shoreline.
Rather than wait for a possible uncontrolled collapse into Cape Cod Bay - which a Woods Hole coastal-processes specialist warned could threaten the oyster beds Wellfleet's economy depends on - the Wellfleet Conservation Commission extended compliance deadlines to June 1, and the house was demolished by excavators on Monday, February 24, 2025, per WBUR's reporting, with some debris intentionally allowed to fall down the bluff rather than risk a later uncontrolled collapse. The town had previously rejected seawall proposals from both the original and subsequent owners, citing state regulations and the ecological effects of coastal armoring. This is a fully verifiable, dated, named event that ties together erosion, storm exposure, and local government in one place - and it happened on the calmer-seeming Cape Cod Bay side of town, not the more commonly discussed Atlantic shoreline, which is itself a useful corrective for anyone assuming bay-side property is automatically lower-risk.
Coastal Erosion: Official Rates With Real Precision
Beyond the Blasch House hot spot, the Massachusetts Coastal Erosion Commission's 2015 report - cited directly in Wellfleet's own 2022 Hazard Mitigation Plan - gives town-wide and shoreline-specific erosion rates with stated error margins: town-wide, short-term -2.3 ± 3.2 ft/year, long-term -1.6 ± 1.8 ft/year; Atlantic Ocean shoreline, short-term -3.1 ± 1.7 ft/year, long-term -2.8 ± 0.3 ft/year; Cape Cod Bay shoreline, short-term -2.0 ± 3.6 ft/year, long-term -1.2 ± 2.0 ft/year. The town's own, simpler beach-erosion page separately states erosion on the Atlantic side "averages 2.9 ft./year" - broadly consistent with the Commission's Atlantic long-term figure, and both sit in the same range as the Outer Cape's roughly 3-feet-per-year average already established on this site's Cape Cod hub page (per USGS Circular 1417).
Those are averages, not a guarantee for any single parcel - the Blasch House site's 3.8-to-5.6-feet-per-year rate shows how far an individual property can run above the town-wide number. Anyone evaluating a specific bluff or bank lot in Wellfleet should ask directly whether it's been the subject of any site-specific erosion study, rather than relying on the town-wide average alone.
FEMA Flood Zones and the CRS Discount: A Genuinely Better Standing Than Some Neighbors
Per Wellfleet's own 2022 Hazard Mitigation Plan, the 2019 FEMA Flood Insurance Rate Map (FIRM) depicts areas of Wellfleet in both V-zones (FEMA's highest-hazard, wave-action coastal designation) and A-zones, plus areas subject to a 2%-annual-chance flood - specific zone-by-zone acreage wasn't broken out in the plan as fetched for this research pass, and should be confirmed on the current FEMA map for any specific parcel.
On the insurance-discount side, there's a genuinely positive, comparative fact worth stating plainly: per a real-estate-industry summary of FEMA's Risk Rating 2.0 rollout, Wellfleet sits in the 15% Community Rating System (CRS) discount tier - the better of two tiers found among participating Cape towns (alongside Chatham, Harwich, Mashpee, Orleans, and Sandwich), versus a 10% tier for Brewster, Eastham, and Provincetown. That's independently corroborated by Wellfleet's own Hazard Mitigation Plan, which states that completing the plan's five-year update was "critical for the Town to maintain its Community Rating System level which reduces flood insurance cost for property owners," and names a dedicated Floodplain Specialist & CRS Coordinator on staff. This is a meaningfully better standing than some neighboring towns' - a real, if modest, silver lining alongside the flood and erosion risk documented above.
What This Page Cannot Tell You
To be direct about the limits of this page: it does not state a Wellfleet-specific damage figure, wind speed, or storm-surge height for the 1938 Hurricane or Hurricane Bob, because none was found despite genuinely thorough searching. The regional figures above - 1938's 18-to-25-foot storm tides and Falmouth's roughly 8 feet of flooding, Bob's roughly 5.8-foot Buzzards Bay surge and $1 billion-plus Massachusetts damage total - describe Cape Cod and Massachusetts broadly, not Wellfleet specifically.
It also doesn't state a town-specific V-zone or A-zone acreage or percentage breakdown, doesn't state Wellfleet's exact current flood-insurance premiums, and doesn't confirm a sourced summer/seasonal population multiplier for the town (the town's own ~17,000 estimate and a widely repeated "nearly sixfold" figure disagree and weren't reconciled in research for this page). Hurricane, nor'easter, and flood risk for any specific Wellfleet property should be assessed using current FEMA flood maps, MEMA evacuation-zone data, a licensed insurance professional, and the Town of Wellfleet's own floodplain and emergency-management materials - not assumptions carried over from a neighboring town, and not the regional history above treated as if it were a Wellfleet-specific record. Nothing on this page is insurance or engineering advice.

Despite a thorough research pass, no Wellfleet-specific dollar-damage figures, wind readings, or storm-surge heights were found for the 1938 Great New England Hurricane or Hurricane Bob (August 19, 1991) - only general Cape Cod-wide and Massachusetts-wide totals exist in the sources checked, and those are presented here as regional context via this site's Cape Cod hub page, not as Wellfleet-specific claims. Regional figures cited: the 1938 Hurricane's 121 mph sustained winds (Blue Hill Observatory) with gusts to 186 mph, storm tides of 18 to 25 feet, and Falmouth's roughly 8 feet of flooding, plus Massachusetts' 99 deaths and Southern New England's 564 deaths (National Weather Service); and Hurricane Bob's (1991) 100 mph sustained winds in Provincetown, roughly 5.8-foot Buzzards Bay/Woods Hole storm surge, and over $1 billion in Massachusetts damage - all regional figures documented on the Cape Cod hub page, not Wellfleet-specific ones. In place of a fabricated Wellfleet hurricane-damage figure, this page instead documents the March 1-3, 2018 nor'easter as real, storm-driven, Wellfleet-specific evidence, per the Town of Wellfleet's own 2022 Hazard Mitigation Plan: "extensive coastal flooding" and a Federal Disaster Declaration, and a "HIGHLY LIKELY" flooding-probability rating for the town. Also documented: the "Blasch House" bluff collapse and controlled demolition on Cape Cod Bay (WBUR, Feb. 5 and Feb. 26, 2025) - a 5,100-square-foot home built 2010, purchased 2022 for $5.5 million, sitting on a bluff a Woods Hole Oceanographic Institution report found eroding at 3.8 to 5.6 feet per year (54 feet total recession since 2014), demolished February 24, 2025 after the Wellfleet Conservation Commission extended compliance deadlines and the town rejected prior seawall proposals. Erosion-rate data per the Massachusetts Coastal Erosion Commission's 2015 report as cited in Wellfleet's own Hazard Mitigation Plan: town-wide short-term -2.3 ± 3.2 ft/year and long-term -1.6 ± 1.8 ft/year; Atlantic shoreline short-term -3.1 ± 1.7 ft/year and long-term -2.8 ± 0.3 ft/year; Cape Cod Bay shoreline short-term -2.0 ± 3.6 ft/year and long-term -1.2 ± 2.0 ft/year; and the town's own beach-erosion page's separate Atlantic-side average of 2.9 ft/year. FEMA flood-zone information (V-zones, A-zones, and 2%-annual-chance flood areas per the 2019 FIRM) and Wellfleet's 15% FEMA Community Rating System discount tier (versus a 10% tier for Brewster, Eastham, and Provincetown) are both per the town's own 2022 Hazard Mitigation Plan and a real-estate-industry summary of FEMA's Risk Rating 2.0 rollout. This page does not provide current FEMA flood-zone, MEMA evacuation-zone, CRS/insurance-discount, or engineering determinations for any individual property - confirm current flood-zone designation, evacuation-zone status, and insurance-discount status directly with the Town of Wellfleet and a licensed Massachusetts insurance professional.
