Americans from cold climates don't like roughing it through winter, as evidenced by the spiking hotel prices. But the Big Island's rates are lower than some of the other popular Hawaiian islands, so you might find a room for less than $200 a night. Keep in mind that this can be a rainier season on the island. And although surfing isn't as popular here as on Kauai or Maui, you will still find the best waves in this peak season. Plus, prime whale-watching season runs from January to early April.

Key Events:

• Mitsubishi Electric Championship at Hualalai (January)
• Waimea Ocean Film Festival (January)

While you might find a good deal in winter, you'll almost definitely find a reasonable room rate in this tiny pocket of time. Just be sure to avoid a Memorial Day trip – some people like to plan extended time off around built-in holidays in their work calendar, so there could be more crowds.

Key Events:

• Ka'u Coffee Festival (April-May)
• Big Island Chocolate Festival (April)

There's a bit of a jump in airfare and hotel rates as families begin to arrive on the Big Island. There's also a slight (but most likely, unnoticeable) rise in temperatures in summer; highs can reach the low 80s.

Key Events:

• King Kamehameha Day Celebration (June)
• Pu'uhonua o Honaunau Hawaiian Cultural Festival (June)
