The 1927 Atlantic hurricane season was a relatively inactive season, with eight tropical storms, four of which became hurricanes. One of these became a major hurricane – Category 3 or higher on the modern day Saffir–Simpson scale.|group="nb" 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 a metric used to express the energy used by a tropical cyclone during its lifetime. Therefore, a storm with a longer duration will have high values of ACE. It is only calculated at six-hour increments in which specific tropical and subtropical systems are either at or above sustained wind speeds of 39 mph (63 km/h), which is the threshold for tropical storm intensity. Thus, tropical depressions are not included here.

Systems
August tropical depression
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. 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 . The latter was observed by the S.S. Maraval, while the former was estimated using the pressure-wind relationship. and Rhode Island, with flooding in the Providence area damaging pavement and overflowing sewers. Along the coast of Massachusetts, rough seas disrupted shipping in Boston and beached a ship at Cape Cod. Of the 173-192 fatalities in Canada, most of them occurred due to damaged or missing ships, with two boats losing their entire crew. On land, heavy rainfall in Nova Scotia washed out 20–25 percent of the rail lines, which disrupted rail service. Flooding also damaged numerous roads and swept away bridges. Crop damage from the hurricane was severe as the storm destroyed about half of the fruit, vegetable, and hay harvest, leaving a loss of $1 million (1927 CAD). Property damage in the province was in the thousands of dollars range and there were many electrical and telephone service outages. Similar but less severe impact occurred in New Brunswick and Prince Edward Island. The storm also left minor wind damage in Newfoundland. Overall, the hurricane caused just under $1.6 million (1927 CAD) in damage.
Hurricane Two
A tropical wave developed into the second tropical depression of the season on September 2,
Tropical Storm Six
The season's next cyclone developed from over the northwestern Caribbean Sea from a broad low pressure area near the Bay Islands Department of Honduras on October 16. Heavy rains caused some crop damage but little else of consequence.
Tropical Storm Eight
The final tropical cyclone of the season developed from a low pressure area early on November 19, while situated about east-northeast of Barbuda.
