All Months
Kailua-Kona enjoys year-round sunshine thanks to its location on the Big Island's dry side. The best months are April through June and September through November – you'll get perfect weather without the peak season crowds or prices. Summer brings more families and higher hotel rates, but the ocean is warmest for swimming and snorkeling. Winter sees occasional rain and bigger surf, but temperatures still hover around 80°F. Here's what most people don't know – October is Ironman month, transforming the quiet town into an athlete's paradise. Hotel rates spike, restaurants book solid, and Ali'i Drive closes for the race. It's electric if you're into triathlon culture, exhausting if you're not. The shoulder seasons of April-May and September-November offer the sweet spot of good weather, reasonable prices, and manageable crowds.
