How Much Do You Know About North Atlantic Hurricanes?

During which months do hurricanes typically occur in the North Atlantic?

What is the main reason for the occurrences of hurricanes in the North Atlantic during the months they typically occur?

Hurricanes generally occur in the North Atlantic from May through November, with the peak of the hurricane season in the September; only rarely will they occur from December through April in that part of the ocean. The main reason for the occurrences of hurricanes during this period is that the temperature on the water’s surface is at its warmest and the humidity of the air is at its highest. Of the tropical storms that occur each year in the North Atlantic, only about five, on the average, are powerful enough to be called hurricanes. To be classified as a hurricane, a tropical storm must have winds reaching speeds of at least 117 kilometers per hour, but the winds are often much stronger than that; the winds of intense hurricanes can easily surpass 240 kilometers per hour.
