, featuring one major hurricane. The first tropical cyclone of the season, Alvin, developed on May 27, while the final system of the year, Kiko, dissipated on October 23. Due to unusually strong wind shear, activity fell short of the long-term average, with a total of 11 named storms, 4 hurricanes, and 1 major hurricane. At the time, 2007 featured the second-lowest value of the

passed offshore the coastline of southwestern Mexico, killing 11 and causing minimal damage. Hurricane Flossie followed a similar track to Cosme in mid-August, producing gusty winds and light precipitation in Hawaii. Hurricane Henriette in early September produced torrential rainfall in southwestern Mexico, killing 6 and causing $25 million in damage. Baja California received moderate rains from Hurricane Ivo in mid-September, though no damage nor fatalities were reported. In mid-October, Tropical Storm Kiko passed just offshore the coastline of southwestern Mexico. Though no deaths were reported on the Mexico mainland, the storm capsized a ship with 30 people on board, 15 of whom were recovered dead, and 9 of whom were reported missing. Overall, the season ended with $80 million in damage and 49 deaths.

The activity was an active year for this basin; it was the most destructive season in known history at this time, only for the 2008 season to surpass it the next year. 2007 was also the first season to have multiple Category 5 cyclones (by the Saffir–Simpson scale), and the two Category 5's, Sidr and Gonu, were also the first named Category 5 cyclones to form in their respective seas; Gonu in the Arabian Sea, and Sidr in the Bay of Bengal. Other notable storms of the season include Akash and Yemyin, both of which caused substantial damage and deaths. At least 4,545 deaths were reported, and damage was about 6.4 billion dollars.
