Mid-April to early June, or September to mid-December (shoulder seasons). During these shoulder seasons visitors enjoy warm weather (low-to-mid 80s°F), lower crowds, lower hotel rates, and lower airfares compared to peak summer and holiday periods. The sea stays warm and swimmable. September adds the Aloha Festivals. Spring avoids the rainy-season peak (Nov–Mar) while still being dry and sunny
