November brings comfortable temperatures to the Kona coast but remains near the end of Pacific hurricane season through November 30; monitor forecasts in the days before and during travel. Pack lightweight breathable clothing, reef-safe sunscreen, a light jacket for cooler evenings, and reef shoes for rocky shoreline spots. For airport comfort at Dallas/Fort Worth International Airport (DFW), bring a portable charger, noise-cancelling headphones, and download boarding passes to speed up check-in. Book snorkeling, coffee farm tours, and shuttles well in advance — festival weekends and holiday weeks fill up fast.
