The 2010 Pacific hurricane season was the least active Pacific hurricane season on record (reliable records began in 1971), tied with 1977. The season accumulated the second-fewest ACE units on record, as many of the tropical cyclones were weak and short-lived. Altogether, only three of the season's eight named storms strengthened into hurricanes. Of those, two became major hurricanes, with one, Celia, reaching Category 5 intensity on the Saffir-Simpson scale. Despite the inactivity, however, it was the costliest Pacific hurricane season on record at the time, mostly due to Tropical Storm Agatha. The season officially began on May 15 in the eastern North Pacific (east 140°W) and on June 1 in the central North Pacific (from 140°W to the International Date Line). It ended in both regions on November 30. These dates, adopted by convention, historically describe the period in each year when most tropical cyclogenesis occurs in these regions of the Pacific. However, the formation of tropical cyclones is possible at any time of the year, as evidenced by the formation of Tropical Storm Omeka on December 19.

The first system of the season, Agatha, developed on May 29 near the coast of Guatemala. In the second week of June, a sudden spree of tropical cyclones developed, and between June 16 and 22, four cyclones formed, including the two major hurricanes of the season, Celia and Darby, the first of which reached Category 5 intensity. This near-record activity was a reversal from the previous season, when no storm formed until June 18. Following this activity, July saw zero named storms. In August and September only 2 tropical storms and one hurricane formed. Tropical Depression Eleven-E caused a great deal of flooding in southern Mexico, causing millions of dollars in damage, as well as causing over 50 deaths and $500 million in damage in areas of Oaxaca and Guatemala. Tropical Storm Omeka was a rare off-season storm.
