The 1954 Pacific hurricane season featured below-average activity, with eleven tropical storms identified. The season officially started on May 15 and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. The majority of the year's storm remained offshore and caused little to no adverse impact on land. However, a tropical storm in October brought flooding rain to Mexico and Guatemala that left five people dead and thousands homeless. An unknown disease in the storm's wake killed a further 35 people.
