Cape Cod Hurricane & Storm Risk: The 1938 Hurricane, Bob, and the Nor'easters In Between

The 1938 Great New England Hurricane: Get the Death Toll Right

On September 21, 1938, a hurricane that had accelerated up the Atlantic seaboard with little warning made landfall as a Category 3 storm. The Blue Hill Observatory, southwest of Boston, recorded sustained winds of 121 mph with gusts to 186 mph — among the highest wind readings ever recorded in New England. Storm tides ran 18 to 25 feet from New London, Connecticut, east through Cape Cod, and parts of Falmouth were left under 8 feet of water. It remains the benchmark against which every other Cape Cod storm is measured, and for good reason: nothing since has matched its combination of wind speed, surge height, and total destruction across the region.

Where accounts of the 1938 hurricane go wrong is the death toll, because the "right" number depends entirely on what area is being described, and most retellings quote a figure without saying which scale it belongs to. At the narrowest scale, Massachusetts alone, Wikipedia's sourced historical accounts put the toll at 99 deaths. At the regional scale — Massachusetts, Rhode Island, and Connecticut together, the area meteorologists call Southern New England — the National Weather Service's Boston/Norton office, the most authoritative federal source at that scale, cites 564 deaths. At the widest scale, the entire storm track across all of New England plus Long Island, New York, the commonly cited range runs from 682 to 800 deaths. These are three genuinely different numbers describing three genuinely different areas, not three competing estimates of the same thing. If you need a Massachusetts-specific figure, 99 is the number to use. If you need a Southern New England regional figure, the NWS's 564 is the authoritative one. Citing "682" or "700-plus" as if it were the Massachusetts or Cape Cod toll specifically is the single most common factual error in casual write-ups of this storm, and it's worth actively correcting rather than repeating.

Hurricane Bob (1991): The Storm Cape Cod Actually Remembers

Hurricane Bob made landfall in Rhode Island in August 1991 as a Category 2 storm, but its effects on Cape Cod were severe and well documented. Provincetown, at the very tip of the Cape, recorded sustained winds of 100 mph, and an unofficial gust of 125 mph was measured in the Brewster/North Truro area. Storm surge peaked at roughly 5.8 feet in Buzzards Bay and Woods Hole. Massachusetts sustained over $1 billion in damage and one death from the storm.

The power outage alone illustrates how thoroughly Bob affected the peninsula: more than 500,000 customers lost power, including all of Cape Cod, with some areas left without electricity for two weeks or more. Erosion damage was severe and specifically documented — Chatham Light saw a 5-foot erosion cliff carved into the bluff, and beach loss elsewhere on the Cape ran as high as 50 feet in places. For anyone weighing storm risk on the Cape today, Bob is arguably the more relevant reference point than 1938: it's the most recent hurricane to hit the region with genuinely severe, well-recorded local effects, and it happened within the lifetime of most current homeowners.

1954: Carol and Edna, Back to Back

Hurricanes Carol and Edna both struck in 1954, within about a week of each other, and both significantly affected Cape Cod and the Islands. Edna produced wind gusts of 120 mph on Martha's Vineyard and drove severe flooding across Cape Cod and the Islands. The two storms together are a reminder that the Cape's hurricane exposure isn't limited to the handful of storms — 1938 and Bob — that get the most attention; the mid-1950s saw a genuine cluster of damaging storms in quick succession.

Nor'easters: The More Frequent, Less Dramatic Threat

Hurricanes get the historical attention, but nor'easters are the more frequent recurring storm risk on Cape Cod, even though no single NOAA or National Weather Service document directly compares the two frequencies for the Cape specifically. A Woods Hole Sea Grant bulletin, hosted on capecod.gov, cites an average of 12 nor'easters impacting Massachusetts annually — a statewide figure, not one specific to the Cape, but a useful baseline for how often this kind of storm arrives somewhere in the state.

On the hurricane side, a third-party statistical aggregator using NOAA's HURDAT hurricane-track database (not a NOAA or NWS publication itself) puts Cape-Cod-specific tropical system activity at roughly a brush or hit every 2.37 years, a direct hurricane-force hit every 9.63 years, and a major hurricane hit roughly every 77 years. Put those two figures side by side and an approximate picture emerges: nor'easters arrive far more often — something on the order of a dozen times a year somewhere in Massachusetts — while hurricane-force impacts specific to the Cape are closer to a once-a-decade event, and major hurricanes closer to a once-in-a-lifetime one. That comparison is a synthesis of two different source types, not a single authoritative statistic, and it should be treated that way: nor'easters are the more frequent, chronic threat, while hurricanes are the rarer but often more locally severe one.

What This Page Is — and Isn't

This page is a historical and factual reference for the Cape Cod region as a whole, drawn from the sources cited above. It is not a substitute for a professional storm-risk assessment on any specific property. Anyone evaluating hurricane or storm risk for a Cape Cod purchase should confirm coverage, cost, and current risk designations with a licensed insurance agent, and should check evacuation zones, storm preparedness resources, and local emergency planning directly with the relevant town's emergency management office — each of the Cape's 15 towns runs its own. Nothing on this page is meteorological, engineering, or insurance advice.
