The 1927 Atlantic hurricane season featured no hurricane landfalls in the United States, in contrast to the four hurricanes that struck the United States in the previous season. Overall, the season was relatively inactive, with eight tropical storms, four of which became hurricanes. One of these became a major hurricane, which is Category 3 or higher on the modern day Saffir–Simpson hurricane wind scale. The first system, a tropical depression, developed on August 13, while the final cyclone, a tropical storm, merged with a cold front on November 21. The most significant storm of the season was Hurricane One, nicknamed the Nova Scotia hurricane. The sole major hurricane, this storm resulted in between 173 and 192 deaths in Atlantic Canada, mostly from capsized and missing ships offshore. On land, the storm left about $1.7 million (1927 USD) in damage, with much of the damage occurring in Nova Scotia. Additionally, the fourth, fifth, and sixth tropical storms brought minor impact to Bermuda, South Carolina, and Cuba, respectively.
The season's activity was reflected with an accumulated cyclone energy (ACE) rating of 56. ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. It is only calculated for full advisories on tropical systems at or exceeding 39 mph (63 km/h), which is tropical storm strength.
A low pressure area formerly associated with a weakening frontal boundary developed into a tropical depression on August 13. The depression moved rapidly east-northeastward and was soon absorbed by the frontal boundary.
A tropical storm developed from a tropical wave over the deep tropics of the Atlantic Ocean on August 18. Moving west-northwestward, it intensified into a Category 1 hurricane on the modern day Saffir–Simpson hurricane wind scale by August 19. The storm deepened significantly over the next few days, and by August 22, it peaked as a Category 3 hurricane with sustained winds of 125 mph (205 km/h) and a minimum pressure of 950 mbar (28 inHg). The latter was observed by the S.S. Maraval, while the former was estimated using the pressure-wind relationship. Around that time, the system began curving northwestward and later northward. By August 23, it turned to the north-northeast and then began weakening on August 24. Thereafter, the storm accelerated toward Atlantic Canada. Late on August 24, the hurricane struck near Yarmouth, Nova Scotia, as a Category 2 hurricane, just before becoming extratropical. The remnants continued northeastward, striking Newfoundland and later Iceland, before dissipating near Jan Mayen on August 29.
