Eastern & Central Pacific Oceans

2021 Pacific hurricane season summary map

The 2021 Pacific hurricane season began on May 15 in the East Pacific and on June 1 in the Central Pacific. Overall activity included 19 named storms, 8 hurricanes, and 2 major hurricanes. The total of named storms was above the 1991–2020 average, while the number of hurricanes was average, and the sum of major hurricanes was below average. The official start date was preceded by the formation of Tropical Storm Andres, the earliest named storm on record in the East Pacific. It was accompanied by Tropical Storm Blanca later in May. The following month included the formations of tropical storms Carlos and Dolores, in addition to Hurricane Enrique. While Carlos remained away from land, Dolores made landfall on the Mexico coastline and Enrique delivered impacts across southwestern sections of the country while it passed just offshore. Above-average seasonal activity continued into July with the development of hurricanes Felicia and Hilda, Tropical Storm Guillermo, and Tropical Depression Nine-E; none of these cyclones impacted land. In August, Hurricane Nora made landfall along the west-central coastline of Mexico. Its formation was preceded by Hurricane Linda and tropical storms Ignacio, Kevin, and Marty, which did not impact land. September marked a stark turn around to the activity of the previous months, as it only featured Olaf, which struck

January

January was unusually above-average, with fourteen tropical cyclones forming and seven being named. Before that, two systems crossed into the 2021 season after having formed during the previous year. Danilo was one of the systems that crossed over, peaking as a severe tropical storm and briefly passing near the Mascarene Islands. A tropical depression designated as 05 entered the South-West Indian Ocean basin on December 28 and caused a brief interaction with Danilo before dissipating on January 3. In the Australian region, Cyclone Imogen formed on January 1 and affected Far North Queensland, bringing minimal damage to the area. Following Imogen, Cyclone Joshua, Cyclone Kimi, and Cyclone Lucas developed, with Joshua later entering the South-West Indian Ocean on January 17. Kimi threatened to strike the coast of Queensland, but weakened suddenly due to unexpected wind shear, remaining just offshore instead. Lucas formed on January 25 and entered the South Pacific basin on February 1. Additionally, four tropical lows formed in the basin, out of which one system entered the South-West Indian Ocean basin.
