Hawaii · Month comparison
December vs May
May ranks #1 overall vs December at #12. The best month nobody talks about — near-summer weather at shoulder prices with empty beaches.
December
#12 of 12 months
Worth considering
Christmas peak — the most expensive fortnight in Hawaii, wetter weather, but festive energy.
- ↑Honolulu Marathon (second Sunday in December) is the fifth-largest marathon in the US — over 20,000 runners from 60+ countries, predominantly Japanese participants, race from Aloha Tower through Waikiki at dawn; the race atmosphere and the spectating along Kalakaua Avenue are free and worth attending even for non-runners
- ↑Christmas and New Year in Hawaii deliver a genuinely festive atmosphere — outdoor hula performances, live Hawaiian music at resorts and in shopping centres, and the combination of warm weather with holiday decoration creates a unique version of the season
May
#1 of 12 months
Best match
The best month nobody talks about — near-summer weather at shoulder prices with empty beaches.
- ↑May delivers summer-quality weather — just 24mm of rain, 8.5 sunshine hours daily, and temperatures reaching 29°C — with none of summer's prices or crowds; it is statistically the best month for value-to-conditions ratio across the Hawaiian islands
- ↑Lei Day (May 1) is the Hawaiian cultural celebration of flowers and community — a genuine local event rather than a tourist production, with lei-making competitions, hula performances, and outdoor markets that offer an authentic entry into Hawaiian culture

December trade-offs
- ↓Christmas week (December 23–January 2) is the single most expensive travel period in Hawaii — airfares can be 2–3x standard rates and quality hotels on all islands are fully booked months in advance; budget accommodation is essentially unavailable at short notice
- ↓December is the wettest month of the year: 92mm of rainfall distributed across predominantly the north and east-facing coasts; the wettest years see sustained rainy spells that can dampen Christmas week plans for those based on windward coasts
- ↓The tourist density at peak Christmas makes popular sites feel overwhelmed — Pearl Harbor's USS Arizona Memorial requires timed tickets booked weeks ahead, Waikiki's beachfront is crowded from sunrise to well after sunset, and restaurant queues at popular spots extend to hours
May trade-offs
- ↓Memorial Day weekend (end of May) brings a sharp demand spike — the final days of May see a significant jump in domestic US travel and prices; book accommodation for the Memorial Day long weekend well in advance or accept higher rates
- ↓Some visitor attractions and beach concessions are not yet at full summer hours in early May — a handful of seasonal operations (paddleboard rentals, snorkel tours on certain islands) are still in shoulder-season mode
- ↓May is genuinely post-whale season — anyone specifically visiting for humpback sightings will be disappointed; the whale boats still run but sightings are sporadic rather than reliable
