The 1965 Pacific hurricane season officially began on May 15, 1965 in the Eastern Pacific Ocean and June 1, 1965 in the Central Pacific. It lasted until November 30, 1965. That hurricane season was the least active hurricane season on record. During this season only five tropical storms formed and only one intensified into a hurricane . The first storm of the season, Tropical Storm Natalie, hit the countryside in Mexico . About a week later, Hurricane Odessa became the strongest storm of the season.

Duration September 7th - September 9th
intensity 45 kn (85 km / h ) (1 minute)

The last tropical cyclone of the season, Tropical Storm Tillie, developed on July 7th. Initially the cyclone moved north-northwest, but on September 8, about 160 km southwest of Cabo San Lucas, the storm moved west-northwest. The storm was active for less than 48 hours, Tille dismantled on September 9 at 6:00 a.m. UTC. Although the storm remained at sea, residual moisture was over southern Arizona advected so that a passing cold front triggered the evening of September 9 widespread showers and thunderstorms. In Tusco, precipitation fell 77mm between September 9th and 10th. At two other locations, one in the Santa Catalina Mountains and the other near Sahuarita , 171 mm of precipitation was measured.

Season summary

With just five named storms, the season was well below the 13 storm average. In fact, with only five named storms, this is the lowest number of storms in the hurricane database. Only one tropical cyclone achieved hurricane status, compared to the average of seven per year. 1964 is also one of the few seasons without a major hurricane. However, it is possible that some storms were missed due to the lack of satellite coverage in the area.
