Honolulu Weather FAQ
When is the best time to visit Honolulu?
April-June or September-October offer the best balance — warm, mostly dry weather with fewer crowds and lower prices than peak winter tourist season. Hurricane risk is low in these months.
Does Honolulu have seasons?
Two — a warmer, drier summer (April-October) and a cooler, wetter winter (November-March). The temperature difference is minimal, usually just a few degrees, but rainfall varies significantly.
Does Honolulu get hurricanes?
Rarely but it happens. Hurricane Iniki (1992) caused major damage to Kauai, and tropical systems occasionally track near the Hawaiian islands. Peak risk is July-October.
What is vog?
Volcanic fog — a haze created by sulfur dioxide gas from Kilauea volcano on the Big Island. Trade winds occasionally blow vog to Oahu, creating poor air quality and reduced visibility.
