The warm ocean temperatures of at least 77☏/25☌ have an impact on the air temperature, which is mild the entire year. There are only two seasons the summer - dry season and the winter - rainy season. It is a tropical climate in Hawaii but usually not too hot. Kona is located in the west, therefore excellent to stay here for a couple of days. Showers frequently occur in Hawaii, especially late afternoon and during the night, but not frequently in Kona. The south and the west of Big Island experience less rain.

The popular manta tour is often fully booked even in the shoulder season. Avoiding Crowds Picture provided by Byron Kay from Kona Honu Divers We spotted plenty of manta rays some almost touched us. It's a popular tour and likely to be sold out days before, particularly during weekends. However, sometimes ocean conditions can spoil the trip, especially in the winter and spring from November until March/April. Therefore, the snorkel and dive tour is offered year-round, during the day and in the evening when it is dark outside. So there isn't a precise season for manta rays. The manta rays are here abundant at this specific spot throughout the year.
