Only one storm, Tropical Storm Andrea, made landfall in the United States.
Unlike the U.S., Mexico was battered by eight storms, including three from the Atlantic basin and five from the eastern North Pacific.
In the Atlantic, hurricane activity tends to come in cycles, with the U.S. being in an active cycle that began in 1995, said Chris Landsea, a forecaster at the National Hurricane Center. The cycles last from 25 to 40 years, so it's unclear whether 2013 will be harbinger of things to come.
The relative calm in the Atlantic has no relationship to hurricane activity elsewhere, pointing to the storms that hit Mexico and Typhoon Haiyan, which struck the Philippines Nov. 8, killing more than 5,200.
Last year was the third-busiest on record with 19 named storms. Ten became hurricanes and two were major storms, including Sandy.
