Hawaii · Month comparison
January vs May
May ranks #1 overall vs January at #10. The best month nobody talks about — near-summer weather at shoulder prices with empty beaches.
January
#10 of 12 months
Strong option
Humpback whale season opens and North Shore surf peaks — winter Hawaii at its most dramatic.
- ↑Humpback whale season (January through May) is one of the most reliable whale watching experiences on Earth — Hawaii's waters host 10,000+ North Pacific humpbacks annually, and Maui's Auau Channel is the world's primary breeding ground; surface activity including breaches, tail slaps, and spy-hops is extraordinary from December through April
- ↑North Shore Oahu surf is at its peak in January — the famous Banzai Pipeline and Sunset Beach break at heights of 15–25 feet, and while the Eddie Aikau competition requires a 40-foot swell, watching any January swell from the shore is genuinely spectacular
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

January trade-offs
- ↓January is among the rainiest months of the year: 78mm across the islands (predominantly on the north and east-facing windward coasts) means rainy days are common, particularly on Maui's Road to Hana side and Kauai's North Shore
- ↓Post-Christmas demand keeps prices elevated through January — airfares and accommodation remain well above the shoulder season rates of April–May, and quality properties need booking months in advance
- ↓North Shore surf makes the water completely un-swimmable on Oahu's north coast from October to April — surf is spectacular to watch but the safe swimming beaches are on the south shore (Waikiki) or in protected coves
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
