The 2010 Atlantic hurricane season was the first in a group of three very active Atlantic hurricane seasons. It is tied alongside 1887, 1995, 2011, and 2012 with 19 tropical storms, the third highest count in recorded history. It featured 12 hurricanes, tied with 1969 for the second highest total. Only the quintessential 2005 season saw more activity. The overall tropical cyclone count in the Atlantic exceeded that in the West Pacific for only the second time on record. The season officially began on June 1 and ended on November 30, dates that conventionally delimit the period during each year when tropical cyclone formation is most likely. The first cyclone, Alex intensified into the first June hurricane since Allison in 1995. The month of September featured eight named storms, tying 2002 and 2007 for the record. October featured five hurricanes, just short of the record set in 1870. Finally, Hurricane Tomas became the latest hurricane on record to move through the Windward Islands in late October. Activity was represented with an accumulated cyclone energy (ACE) value of 165 units, which was the eleventh highest value on record at the time.

Numerous tropical cyclones affected countries bordering the Atlantic Ocean throughout 2010. Alex caused 52 deaths and up to $1.52 billion (2010 USD) in damage as it struck northern Mexico in June. The next month, Tropical Storm Bonnie struck Florida as a weak cyclone, leaving one dead. Tropical Storm Colin led to one drowning death, and rip currents produced by Tropical Depression Five killed two people. Hurricane Danielle passed east of Bermuda while Earl moved parallel to the East Coast of the United States and into Nova Scotia throughout late August, resulting in 2 and 8 deaths, respectively. In early September, Tropical Storm Hermine caused significant flooding across Texas and killed 8 people. The strongest hurricane of the year, Igor, killed four as it traversed the Atlantic and across Newfoundland. Latin America was badly hit by Hurricane Karl and Tropical Storm Matthew, with 22 and 126 deaths, respectively. In late September, Tropical Storm Nicole produced torrential rainfall from the Caribbean into the U.S. East Coast, resulting in 16 fatalities. Hurricane Paula caused a tourist to drown offshore Cozumel in mid-October, while Hurricane Richard left two dead in Belize later that month. The season concluded with Tomas which caused 35 fatalities along its track through the Caribbean and into the Atlantic.
