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

Hawaii in January moves at a slightly slower rhythm than usual. The skies are mostly clear, the breezes are soft, and the air smells like salt and hibiscus. Humpback whales are breaching offshore, surf is roaring on the North Shore, and in smaller towns, locals are still packing away holiday lights.

You can hike through misty rainforest trails in the morning, then warm up on sun-drenched beaches by noon. It’s the kind of trip that doesn’t need to be packed with plans — just well-timed moments. An advisor from TravelJoy can help you reserve a guided hike through the Waihou Spring Forest Reserve when the trails are quiet, pair it with mid-morning snorkeling in calmer winter waters off Poʻipū, or time your route so you're in Lāhainā just as the afternoon light hits the humpback whales offshore.

January brings some of Hawaii’s coolest weather, but that still means daytime highs in the upper 70s and low 80s across most islands. Nights are cooler, often dipping into the mid-60s, so it’s a good idea to pack a light sweater. Rain showers are more likely in winter, especially on the windward sides, but they’re usually brief. The sea remains warm enough for swimming and snorkeling, while the cooler air makes hikes and sightseeing more enjoyable.

Because it falls in the middle of Hawaii’s winter high season, January does draw more visitors—especially around New Year’s. That means popular spots like Waikīkī or parts of Maui will feel lively and a little more crowded. But it’s also a good time to explore the quieter corners: maybe take a long drive along Kaua‘i’s south shore or wander the farmers markets on the Hilo side of the Big Island. It’s also peak whale season, and surf competitions on the North Shore bring a local buzz that’s worth catching.

Even with January being peak season, things start to ease up after the New Year’s rush. That’s when the islands settle into a slower rhythm — fewer lines, more availability, and a little extra room to breathe. An advisor from TravelJoy can help you make the most of this precious time by planning a sunrise hike on the Sliding Sands Trail in Haleakalā, arranging a whale-watching tour during peak migration near Maui, or booking a stargazing experience atop Mauna Kea when the skies are clearest. With proper planning, January in Hawaii feels like the perfect balance of festive energy and calm moments.
