Best Time to Visit Kauai

Kauai maintains tropical island temperatures year-round, with high temperatures staying in the mid-70s. While the temperature remains consistent, travelers should consider other factors such as swimming conditions, peak tourism times, whale watching season, and rainfall when deciding the best time to visit Kauai.

Kauai Tourism Off-Season

For a quieter and more relaxed trip (not to mention lower prices), travel during the off-season for Kauai tourism, which falls during spring (mid-April to mid-June) and fall (September to mid-December). This allows for greater savings on flights, vacation rentals, rental cars, and activities around the island. Though you will always be able to find space to yourself on many of Kauai’s beaches year-round, the most popular beaches will be much less crowded during the off-season, making tours and activities easier to book.


Kauai is warm year-round and short rain showers throughout the day are common. Some seasons are rainier than others, however, with November through March being the rainy period and summer months corresponding with the dry season. But even during rainy time of year, there’s always sunshine to be found somewhere on the island, especially on the south side and drier west coast.

Whale Watching Season

If you hope to do any whale watching while on Kauai, be sure to plan a trip for November through March. This is when humpback whales can be seen breaching and slapping their tails. January and February are peak seasons, with boat tours geared toward whale watching being a popular activity.


Kauai’s waves change with the seasons, making the best time surfing and swimming spots change depending on the time of year. Generally during winter months, the North Shore sees large waves, making many of the beaches dangerous for swimming and Kauai tourism. The North Shore is usually fairy calm and flat in the summer. It is the opposite on the south shore, which sees large waves during the summer and calmer conditions during the winter. Conditions on the east and west coasts can vary, with swells from the north and south potentially wrapping around the island.
