Strengthening El Nino Expected to Influence Hawaii’s Hurricane Season

Honolulu, HI, October 9, 2026 — The upcoming hurricane season in Hawaii is expected to be influenced by a strengthening El Nino phenomenon, according to meteorological outlooks. El Nino, a climate pattern characterized by warmer-than-average sea surface temperatures in the central and eastern tropical Pacific Ocean, typically alters global weather patterns.

Meteorologists observe that El Nino often leads to increased wind shear across the tropical Atlantic and eastern North Pacific basins, which can disrupt hurricane formation and intensification. However, for the Hawaiian Islands, the impact can be more complex. While increased wind shear might suppress storm development in some areas, the presence of El Nino can also contribute to an environment where storms that do form are steered more directly toward the islands.

The specific degree to which this particular El Nino will affect Hawaii’s hurricane season remains a subject of ongoing analysis by climate scientists. Factors such as the exact strength and duration of the El Nino, as well as other concurrent climate drivers, will play a role in determining the seasonal outlook.

Hawaii is typically most vulnerable to tropical cyclones during the months of August, September, and October. Residents and emergency management officials are advised to stay informed about forecasts and to prepare for potential impacts. Further updates on hurricane season forecasts will be provided as they become available from official sources.
