The 1959 Pacific hurricane season featured the first two Category 5 hurricanes ever recorded in the Eastern and Central Pacific basins.

During the season, 15 storms developed, 5 of those became hurricanes, and 3 of those became major hurricanes. The strongest of the storms was Hurricane Patsy, which was a Category 5 but luckily stayed out to sea. Patsy reached 170 miles per hour (270 km/h) winds. The deadliest storm of the season was Hurricane Fifteen, which made landfall in Mexico at Category 5 and killed 1,800 people.

Storms


Tropical Storm One

Tropical storm (SSHS)
Duration June 9 – June 12
Intensity 45 mph (75 km/h) (1-min),  Unknown

A 55 mph (75 km/h) tropical storm was first located on June 9 while west of Mexico.[1] It did not strengthen any further as it paralleled the Mexican coast.[1] It made landfall near Los Mochis, Mexico on June 12 and dissipated shortly afterward.[1] There are no reports of damages or deaths due to the storm.

Tropical Storm Two

Tropical storm (SSHS)
Duration June 25 – June 27
Intensity 50 mph (85 km/h) (1-min),  Unknown

On June 25, a small tropical storm developed off the coast of Mexico. It attained winds of 45 mph at its peak. It later dissipated on June 27.[2]

Tropical Storm Three

Tropical storm (SSHS)
Duration July 16 – July 22
Intensity 50 mph (85 km/h) (1-min),  Unknown

After a month of inactivity, a tropical storm formed several thousands of miles south-west of the southern tip of Baja California. This tropical storm began moving north-westwards while keeping its intensity. Winds peaked at 50 mph (85 km/h). On July 19, this tropical storm began moving west and finally dissipated 3 days later. [3]

Tropical Storm Four

Tropical storm (SSHS)
Duration July 22 – July 25
Intensity 50 mph (85 km/h) (1-min),  Unknown

Soon after Tropical Storm Three dissipated, a new tropical storm formed in the open Pacific. Tropical Storm Four moved west, then west-north-west. Like the previous 2 tropical storms, it did not affect land. It dissipated on July 25.[4]

Tropical Storm Five

Tropical storm (SSHS)
Duration July 29 – July 30
Intensity 45 mph (75 km/h) (1-min),  Unknown

Tropical Storm Five was a short-lived tropical storm, only lasting a day. It peaked at a relatively weak 45 mph (75 km/h). It moved parallel to the Mexican coast. [5]

Hurricane Dot

Category 4 hurricane (SSHS)
Duration August 1 – August 8
Intensity 150 mph (240 km/h) (1-min),  952 mbar (hPa)

On August 1, Tropical Storm Dot was first seen southeast of Hawaii. It moved westward, strengthening to a 150 mph (240 km/h) Category 4 hurricane before turning to the northwest. It crossed over the northwestern Hawaiian islands as a minimal hurricane, and dissipated on the 8th. Dot caused around $5.5 million in damage.

Tropical Storm Seven

Tropical storm (SSHS)
Duration August 4 – August 6
Intensity 45 mph (75 km/h) (1-min),  Unknown

On August 4, a tropical storm formed at about 26°N, the normal place for tropical cyclone formation. This system gradually moved east and then turned to the west-south-west late on August 5. It dissipated a couple of hours later.

Tropical Storm Eight

Tropical storm (SSHS)
Duration August 19 – August 21
Intensity 45 mph (75 km/h) (1-min),  Unknown

Tropical Storm Eight formed on August 19, a several hundred miles west of Mexico. This system did not affect land so no deaths or damages were contributed to this tropical storm. [6]

Tropical Storm Nine

Tropical storm (SSHS)
Duration August 27 – August 29
Intensity 45 mph (75 km/h) (1-min),  Unknown

Just days after Tropical Storm Eight dissipated, meteorologists noticed a new tropical system that, once again, was out at sea. Although the storm reached 45 mph winds, it only lasted 2 days. [7]

Hurricane Ten

Category 1 hurricane (SSHS)
Duration September 4 – September 11
Intensity 85 mph (140 km/h) (1-min),  Unknown

Hurricane Ten formed off the coast of Guatemala as a Category 1 hurricane. It nearly made landfall on September 6. The system turned to the north, then NNW on September 7. It made landfall in Baja California Sur and continued along the state before weakening to a tropical storm, then a tropical depression. It dissipated near the USA-Mexico border. [8]

Hurricane Patsy

Category 5 hurricane (SSHS)
Duration September 6 – September 10
Intensity 170 mph (275 km/h) (1-min),  Unknown

On September 6, reports from aircraft indicated the existence of a tropical storm near the international dateline. Earlier stages were missed because of a lack of data in the isolated area. A trough moved Patsy northeast. A second trough then developed, dominated over the first, and recurved Patsy northeast. It then slowly headed northwards and gradually weakened. It dissipated on September 10. Patsy's erratic path near the dateline was unusual and no known tropical cyclone had taken such a path over the previous ten years,[9] although that of Typhoon June 1958 was somewhat similar.[10]

The National Hurricane Center's "best track" data set has Patsy exclusively east of the dateline from detection to dissipation.[11] The Japan Meteorological Agency's "best track" does not give windspeeds, only indicating that Patsy was a typhoon.[12] The Joint Typhoon Warning Center's report disagrees on location but also has Patsy's maximum windspeed east of the dateline;[9] the JMA's data does not indicate windspeeds.[12] By reaching Category 5 intensity on September 6, 1959 it is the earliest known Pacific hurricane to reach that intensity on the Saffir-Simpson Hurricane Scale.[11] Also, its maximum reported windspeed of 150 knots (280 km/h) makes it the central Pacific hurricane with the highest sustained winds; Hurricane John tied this record in 1994. In addition, Patsy is an uncommon west-to-east crosser of the dateline. Including only systems recognized by the Central Pacific Hurricane Center, that has only happened six times since.[13]

Hurricane Twelve

Category 1 hurricane (SSHS)
Duration September 21 – September 26
Intensity 85 mph (140 km/h) (1-min),  967 mbar (hPa)

Twelve stayed to sea.

Tropical Storm Wanda

Tropical storm (SSHS)
Duration September 26 – September 27
Intensity 70 mph (110 km/h) (1-min),  Unknown

Tropical Storm Fourteen

Tropical storm (SSHS)
Duration October 19 – October 21
Intensity 50 mph (85 km/h) (1-min),  Unknown

Hurricane Fifteen

Category 5 hurricane (SSHS)
Duration October 23 – October 29
Intensity 160 mph (260 km/h) (1-min),  959 mbar (hPa)

The most notable storm this year was the 1959 Mexico Hurricane. It made landfall as a Category 5 and killed at least 1800 people.
