Best Times to Visit Hawaii - The Big Island
The best time to visit Hawaii's Big Island is between September and November. That's when the island's generally reasonable room rates take the most significant plunge. Temperatures remain constant throughout the year — generally in the high 70s or low 80s — so you might want to avoid the priciest season, from December to March, unless you like to surf.
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 $90 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.
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.
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.
Once again, the room rates dive as the family summer vacation season reaches a close. There are even four-star hotels in Kona that advertise rooms for less than $160 a night. If you're thinking of traveling at this time, lean more toward September and October; November is the rainiest month on Hawaii's Big Island.
