Best time to visit Hawaii for good weather
When is the best weather in Hawaii? Monthly breakdown of temperature, rainfall, and sunshine hours — ranked by what actually matters for your trip.
Best month
May
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
↑Snorkelling conditions on all islands reach their seasonal peak in May: water clarity is excellent, reef fish populations are active, and the calm post-whale-season water makes Molokini Crater (Maui), Hanauma Bay (Oahu), and Kealakekua Bay (Big Island) accessible to all skill levels
