Kauai in January

January is one of the most scenic months to visit Kauai. The island is lush and green, whale-watching season is in full swing, and the North Shore sees powerful winter surf that draws both spectators and experienced surfers to Hanalei Bay. It is also a good month for peaceful hiking and dramatic views across Waimea Canyon, Kokeʻe State Park, and the Nā Pali cliffs between showers.

Where to stay in Kauai

Best for beach vacations

Koloa and Poipu are some of the strongest choices for beach-focused stays, especially if you want sunnier South Shore conditions, swimmable winter beaches, and easy access to restaurants and family-friendly coastal areas.

Best for hiking and nature

Northwest and upland access points near Waimea Canyon, Kokeʻe State Park, and the Nā Pali Coast are strongest for travelers who care most about trails, viewpoints, and dramatic scenery. If hiking and nature are top priorities, spring and fall are usually the smartest times to base a trip around these areas.

Best for scenic North Shore surf spots

Princeville, Hanalei, and Haena are best if you want dramatic coastal scenery, easier access to North Shore beaches and top surf spots, as well as a stronger connection to Kauai’s lush, wilder landscapes. These areas are especially appealing in summer, when ocean conditions are calmer.
