Hawaii in October: Your guide to weather, events & travel

Hawaii in October welcomes you with a sense of easygoing magic. You’ll feel the shift in the air as gentle rains wake up the hillsides, turning trails greener and waterfalls livelier. Farmers’ markets brim with fresh tropical fruit and local harvests, while the ocean stays warm and clear, perfect for a quick swim between exploring small towns and scenic drives.

It’s a time when the islands feel relaxed but full of life, offering everything from laid-back afternoons by the beach to local festivals and fall celebrations. And if you want help finding the best spots or planning around the season’s hidden highlights, an advisor from TravelJoy can help design a trip that checks all the right boxes.

October brings warm, comfortable weather across the islands. Daytime temperatures typically stay in the mid-80s, with evenings dipping into the low 70s—perfect for sunset dinners by the beach or morning hikes through lush valleys. The ocean is at its warmest, making it an excellent month for snorkeling, paddling, or simply floating in calm bays.

It’s also shoulder season in Hawaii. So, you’ll find lighter crowds compared to summer and the winter holidays, and lower hotel rates. Popular spots, from the Hana Highway on Maui to beaches on Oʻahu’s North Shore, feel more relaxed and welcoming.

However, there are a few trade-offs you should keep in mind. October marks the beginning of the rainy season, so you might see brief showers—especially on windward coasts—but they rarely linger. While hurricane season technically continues, major storms hitting Hawaii are rare. Despite the occasional showers, you can enjoy Hawaii’s greener trails and catch local events like the Waikīkī Fall Festival or Molokaʻi Hoe canoe race.

All in all, if you want warm days, fewer crowds, and a laid-back vibe, October is an excellent time to visit. Advisors on TravelJoy can help you pick the best islands for sunny weather, steer you toward leeward-side hotels that stay drier, and suggest seasonal festivals or food events happening this month.
