Atlantic hurricanes have been recorded in every month of the year, I understand.

But have there been as many as this year in one year before?

The number of 'tropical storms' is effectively constant. The proportion which reach hurricane strength has increased, however.

"Instead of examining only the number of tropical storms and hurricanes as an indicator of activity, NOAA's Accumulated Cyclone Energy Index takes into account the cumulative strength and duration of each storm. As shown in the figure to the right, 2005 is the third most active season on record behind 1950, 1995 and 2004 in terms of the ACE index."
