No Atlantic hurricanes hit Mexico throughout September. That’s not normal.
The lull may end soon as Tropical Storm Isaias gains strength, but the last hurricane-free September off Mexico's eastern coast was in 1994, with only two others occurring since 1950 (in 1962 and 1972).

Mexico went an unprecedented nine weeks without a hurricane from the Atlantic during September, a rare occurrence in more than 30 years. Meanwhile, the Pacific coast experienced a tumultuous season with 20 named storms and nine hurricanes, including three Category 5 hurricanes. The primary reason behind this unusual pattern is a strong El Niño in the central and eastern Pacific, which created warmer waters and reduced vertical wind shear, making conditions more favorable for cyclone formation and intensification.
In contrast, the El Niño in the Atlantic increased vertical wind shear, which can disrupt developing storms. Historically, September marked the peak of the Atlantic hurricane season, and this year was no exception, with the first hurricane-free September since 1994. However, the current season may be coming to an end with the formation of Tropical Storm Isaias, which is expected to strengthen and become the first Atlantic hurricane of the 2026 season.
