The 2003 Pacific hurricane season was the first season to feature no major hurricanes – storms of Category 3 intensity or higher on the Saffir–Simpson hurricane wind scale (SSHWS) – since 1977. The dates conventionally delimiting the period when most tropical cyclones form in the Pacific Ocean are May 15 in the Eastern Pacific Ocean and June 1 in the Central Pacific, with both seasons ending on November 30. The 2003 season featured 16 tropical storms between May 19 and October 26; 7 of these became hurricanes, which was then considered an average season. Damage across the basin reached US$129 million, and 23 people were killed by the storms.

Hurricane Olaf was a Category 2 Pacific hurricane that struck the Baja California Peninsula in September 2021. The fifteenth named storm and sixth hurricane of the 2021 Pacific hurricane season, the cyclone formed from an area of low pressure that developed off the southwestern coast of Mexico on September 5. The disturbance developed within a favorable environment, acquiring more convection and a surface circulation. The area was determined to have developed into Tropical Depression Fifteen-E on September 8. The depression strengthened into a tropical storm and was named Olaf at 15:00 UTC that day. Olaf quickly strengthened as it moved to the north-northwest, and was upgraded to a hurricane 24 hours after being named. Hurricane Olaf continued to intensify and reached peak intensity while its center was just offshore the southwestern coast of Baja California Sur, with maximum sustained winds of 105 mph (155 km/h) and a minimum barometric pressure of 968 millibars. Just after reaching peak intensity, the hurricane made landfall near San José del Cabo. Interaction with the mountainous terrain of the Baja California Peninsula caused Olaf to quickly weaken. It was downgraded to a tropical storm at 15:00 UTC on September 10. The system became devoid of convection that day and degenerated to a remnant low at 09:00 UTC on September 11.
