[13] The accumulated cyclone energy (ACE) index for the 2022 Pacific hurricane season, as calculated by Colorado State University using data from the NHC, was 116.5 units, the highest since 2018.

A very favorable environment allowed the system to begin a prolonged period of rapid intensification on May 29; it became the season's first hurricane during the early morning hours and reached its peak intensity at Category 2 strength with winds of 110 mph (175 km/h) by the afternoon.

[17] Moisture from Blas combined with a nearby tropical wave interacted with the mountainous terrain of southwestern Mexico, resulting in heavy rainfall along the coast despite the hurricane remaining well offshore.

[19] A tropical wave departed Africa on June 5 and entered the East Pacific a week later, where it interacted with the active monsoon trough and the favorable phase of the Madden–Julian oscillation (MJO).

Celia soon entered colder waters and drier air, causing it to degenerate to a remnant low on June 28 after an unusually long stint as an early season tropical cyclone.

[20] While stalled off the coast of Central America, Celia interacted with a nearby low-pressure system which brought heavy rainfall to western Guatemala, affecting over 28,000 people.

Beginning several hours afterward and continuing into July 6, Bonnie's cloud pattern deteriorated and the central convection became less organized due to moderate north-northeasterly shear, causing it to weaken to Category 2 strength.

Bonnie's intensity continued to decrease the following day as it moved into cooler waters with sea surface temperatures of 75–77 °F (24–25 °C), where it weakened to a tropical storm about 825 mi (1,330 km) west-southwest of the southern tip of the Baja California peninsula.

The combination of strong wind shear and colder waters caused Darby to dissipate into a trough early on July 17 while located southwest of Hawaii's Big Island.

[26] On July 7, the NHC began monitoring the southeastern Pacific south of the coast of Central America, where a low pressure area was expected to form within a few days.

[29] By 03:00 UTC on July 16, the depression had strengthened, with a well defined low-level structure and a tight band of persistent deep convection near the center, and was upgraded to Tropical Storm Estelle.

[36] Estelle's upper-level cloud shield became more symmetric later that day, due to reduced wind shear and increased convection that had wrapped around the storm's northern region.

[39] Though Estelle remained well off shore, heavy rains were reported in coastal areas of Baja California Sur, Jalisco, Nayarit and Sinaloa, causing localized flooding and landslides.

[54] The system remained relatively unchanged in strength during the next couple of days, though by early on July 29, its cloud pattern had become more symmetric with a well-developed rain band in the north part of the storm, and its sustained winds reached 60 mph (95 km/h).

[55] Then, moving slowly westward, the storm waned over the next couple days, due in part to strong easterly shear generated by the outflow from the circulation of Hurricane Frank, and weakened to a tropical depression on the afternoon of July 31.

[58] On August 2, the NHC began monitoring a tropical wave producing widespread showers and thunderstorms over Central America and the adjacent waters in anticipation that an area of low pressure would form once it moved over the eastern Pacific.

[62] On the afternoon of August 7, the depression was upgraded to Tropical Storm Howard as convection began to build over the northern semicircle of the system, though the low-level circulation remained partially exposed to the south due to continuing wind shear.

[72] It tracked over warm ocean waters, but there was little improvement in its structure due to moderate to strong east-northeasterly shear,[73] until an unexpected burst of convection during the afternoon of August 15 resulted in the intensification of the depression into Tropical Storm Ivette.

[79] Then, fueled by increasing deep convection over the depression's western region and near its center, the system strengthened into Tropical Storm Javier early the next day, though its circulation remained somewhat elongated.

[92] Kay made landfall along the central Baja California peninsula coast with 70 mph (115 km/h) winds on September 8,[93] then continuing to weaken as it moved back over the ocean.

The rainfall was beneficial to crews in Riverside County, California, battling the Fairview Fire, as it mitigated some of the threat posed by the high winds and dry conditions.

[10][95][100] A trough of low pressure producing disorganized showers and thunderstorms extending from the Gulf of Tehuantepec westward to near the southern coast of Mexico formed on September 11.

[111] On September 12, the NHC began monitoring for potential development an small area of low pressure located off the coast of southwestern Mexico producing limited showers and thunderstorms.

[114] As a result, the storm was able to attain maximum sustained winds of 65 mph (100 km/h) on September 19, when located about 175 mi (280 km) south-southeast of the southern tip of the Baja California peninsula.

[123] As the storm moved west-northwestward on September 22, a tiny eye-like feature and new deep convection formed in the core, enabling it to generate sustained winds of 65 mph (100 km/h).

[133] Further development occurred overnight and the system intensified into Tropical Storm Orlene at 09:00 UTC on September 29, while located about 295 mi (475 km) south of Manzanillo, Colima.

[134] The next day, as the storm moved northward along the edge of a ridge over central Mexico, it generated a few bursts of deep convection and developed a small inner core with a curved band to the south.

[143] On September 30, the NHC began monitoring a newly formed area of disturbed weather some 600 mi (970 km) south-southwest of the southern tip of the Baja California peninsula.

[144] Shower and thunderstorm activity within the disturbance increased and began showing signs of becoming organized on October 1,[145] and satellite imagery the following day indicated that its surface circulation had become better defined.

[150] At 21:00 UTC on October 9, Tropical Storm Julia left the Atlantic basin and was designated as an East Pacific system about 45 mi (70 km) west-northwest of Managua, Nicaragua,[151] and its center emerged off shore a few hours later.
