Eastham Hurricane & Storm Risk: What's Known, What Genuinely Isn't

The Confirmed Gap: No Eastham-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 Eastham 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 an Eastham-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 Eastham 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. Given Eastham'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 - including Falmouth's flooding depth or Buzzards Bay's surge height, both cited on the Cape Cod hub page - and present it as Eastham'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 Eastham-specific ones - included because it's the closest documented history to what Eastham'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 Eastham 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 Eastham, 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 Eastham numbers, even though it's reasonable to assume Bob caused real local effects given the town's exposed Outer Cape position.

The 1978 Blizzard: Eastham's Actual Documented Storm Disaster

This is where Eastham's storm story actually lives, and it's a real, sourced, town-specific event rather than a borrowed regional figure: the February 6-7, 1978 nor'easter - the "Blizzard of '78" - produced 92 mph winds at Chatham and a storm tide of 14.5 feet above mean low water at Coast Guard Beach, per the National Park Service's own Coast Guard Beach page. The storm destroyed the beach's parking lot and bathhouse complex outright, and, critically, destroyed Henry Beston's "Outermost House" along with three other homes nearby. Beston's 21-by-16-foot cottage, built in 1925 roughly two miles south of Coast Guard Beach and the subject of his 1928 book "The Outermost House," had been donated to Mass Audubon in 1959; the 1978 storm took it along with the other three structures.

NPS's response is itself a real, sourced planning story: the Park Service relocated Coast Guard Beach's parking lot away from the active shoreline after the 1978 storm, specifically to let natural erosion and accretion continue unimpeded rather than rebuild in the same exposed spot. One honest note on naming: some retellings label this event "Man vs. the Sea," but no primary source - NPS, Wikipedia, or contemporary news coverage - was found using that specific phrase for the storm or the Outermost House's destruction. Every source checked for this page refers to it simply as the Outermost House's destruction in the 1978 blizzard, and that's the version presented here rather than an unverified title.

A Live Erosion Crisis: The Bartlett House, Winter 2023-2024

Eastham's coastal-risk story isn't confined to 1978 - it's playing out on an active, current structure right now. The NPS-owned Bartlett House (built 1960, Seashore-owned since 1964, used for decades as staff housing and a vacation rental) sat 45 feet from the bluff edge in April 2023. By July 2024 it was down to just 13 feet - a loss of roughly 18 feet of bluff in the single winter of November 2023 through April 2024 alone, per a Provincetown Independent report (July 31, 2024). HUD declared the house uninhabitable on July 9, 2024, and NPS moved toward demolition rather than relocation.

That single-winter loss is dramatic, but it sits on top of a longer, well-documented erosion trend: USGS Circular 1417 puts the Outer Cape's average erosion rate at roughly 3 feet per year, with Coast Guard Beach specifically running closer to 3.5 feet per year. A retired NPS cartographer, quoted in the same Provincetown Independent piece, separately described long-term bluff erosion from Eastham to Truro at "about one meter per year" - roughly 3.3 feet - broadly consistent with the Circular 1417 figure, though phrased as a Seashore-wide average rather than an Eastham-specific number in that particular source. The Bartlett House is the clearest current, real-world illustration of that erosion rate actually happening to a named structure, not a hypothetical projection.

Coast Guard Beach's Life-Saving Heritage: A Graveyard for 3,000 Ships

Eastham's storm exposure has a much longer history than any single hurricane or nor'easter, and it's worth understanding as context: Coast Guard Beach's outer shoreline has been, per the National Park Service's own account, "a notorious graveyard for more than 3,000 ships since the wreck of the Sparrowhawk in 1626." That centuries-long wreck record led directly to the Massachusetts Humane Society's founding in 1786 and eventually to the federal Life-Saving Service, established in 1871-72.

The original Nauset life-saving station - rebuilt around 1937 after an 1871 predecessor was itself lost to erosion - operated until 1958, after which it became Cape Cod National Seashore's very first headquarters building in 1961. That means Eastham wasn't just a site the Seashore later protected - it's literally where the Seashore's own administration began, a direct legacy of the same storm-and-shipwreck exposure this page documents elsewhere.

Geography: Nearly Half the Town Is Water

Eastham totals 25.7 square miles, but only 14.0 of those are land - meaning roughly 45.7% of the town is water: Cape Cod Bay, the open Atlantic, Nauset Marsh and Bay, Town Cove, Great Pond, and other kettle ponds. That's a genuinely distinctive number among Cape towns and a useful way to frame storm exposure structurally: a town this water-heavy has meaningfully more shoreline, marsh edge, and pond frontage exposed to wind-driven flooding and storm surge, relative to its land area, than a more land-dominant Cape town of similar total size. This is a geographic observation, not a substitute for a parcel-specific flood-zone determination.

FEMA Flood Zones and CRS Status: What Exists, and What Needs Direct Verification

Eastham's own town website (eastham-ma.gov/329) confirms the town participates in FEMA's Community Rating System, noting that "most Cape Cod towns [can] earn a 5%, 10%, or 15% discount" on flood insurance - but the page as fetched did not state Eastham's own specific discount tier, and that figure should be confirmed directly with the town's Community Development Department or FEMA before relying on it. The same town page confirms Eastham offers residents help identifying flood-plain status, reducing flood-damage risk, and accessing GIS/topographic data.

Given the erosion and 1978-blizzard history documented above, Eastham almost certainly carries meaningful high-hazard coastal flood-zone (V-zone) exposure along its ocean-facing shoreline, but no town-specific V-zone or A-zone acreage or percentage breakdown was independently found in research behind this page - say that plainly rather than guess at it. Eastham also sits atop the Cape Cod Sole Source Aquifer, an EPA-designated, Cape-wide shared drinking-water resource; the town's own hazardous-materials ordinance (Chapter 77) and a dedicated aquifer-protection document confirm that dependency, though it wasn't independently re-detailed beyond confirming its existence this pass.

What This Page Cannot Tell You

To be direct about the limits of this page: it does not state an Eastham-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 Eastham specifically.

It also doesn't state a current FEMA Community Rating System discount percentage for Eastham, doesn't state a town-specific V-zone or A-zone acreage or percentage breakdown, and doesn't confirm a sourced summer/seasonal population multiplier for the town - none of those was independently confirmed in this research pass. Hurricane, nor'easter, and flood risk for any specific Eastham property should be assessed using current FEMA flood maps, MEMA evacuation-zone data, a licensed insurance professional, and the Town of Eastham'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 an Eastham-specific record. Nothing on this page is insurance or engineering advice.
