Kauai Best Time To Visit

Best time to visit Kauai
There’s a reason Kauai is called the Garden Isle: it’s lush and green year round. That greenery is a result of Kauai’s frequent rains. This can be a deterrent to sun seeking travelers, but it shouldn’t be. While yes, rains are frequent, they’re not persistent. And furthermore, those rains lead to frequent rainbows, making Kauai feel like there’s always something special to be found at the other end of that gorgeous arc. Full disclosure: if you want sunny beach days to make up most of your vacation, Kauai may not be for you. But if you’re up for adventure, for hiking and nature, for a vacation that’s off the beach as much as on, you’ll love Kauai.

Best time for a sunbreak vacation
Rainy season on Kauai generally runs from November to March — North American winter. April to September tend to be drier, so that’s when to book your beachy sunbreak. You’ll see the most sunshine in summer, June through August, and you can stack the odds towards sunshine by traveling them. But keep in mind that even though it’s rarely cold on Kauai, the rain can come any time.

Best time for birding
Kauai is prime birdwatching territory, with two locations being the big draw. The Wailua River Valley and the Kilauea Lighthouse. November sees the return of the Laysan Albatross, hatchlings start making their way into the world in December. A number of migratory birds winter over on Kauai — they don’t care about the rain one bit! — making the island a popular destination for list keepers from around the world.

Best time to hike the Kalalau Trail
Heads up! This popular trail was damaged in heavy rains and is currently closed. Check with the tourism board and local sources for updates.
The rugged trail on the Na Pali coast has gorgeous views out across the Pacific. It’s a tough 11 mile slog, up and down the steep, rocky cliffs, but it’s worth every step — even if you quit at the first viewpoint. You need good shoes and water — there are no services — and you’ll want to set out early in the day before the heat rises. The trail is easier to navigate in the drier summer months, but the temperatures are also higher. The full trail is for experienced strong hikers only and confirming conditions locally before you set out is a safety essential.

Best time for Kauai’s art scene
Funky little Hanapepe town has a cool swinging bridge and great places to eat, but it’s also got a regularly lively art scene. Hanapepe Art Night happens every Friday, year round. You’ll find live music, popup galleries and food stands, and an inviting, inclusive scene for tourists and locals alike.

Best time to hike Waimea Canyon
The “Grand Canyon of Hawaii” is a gorgeous natural wonder with its red rock and stellar views. Like anywhere else on the island hikers will do well to start early in the day to avoid the heat. But plenty of visitors come all day, year round, regardless of weather to admire the spectacular views down the Na Pali Coast. The forecast is your best indicator of when to go. If it’s cloudy and the forecast shows no sign of clearing, save it for another day, if you can. The clouds press up against the islands green cliffs, obscuring the view. Blue skies at the canyon rim are no guarantee of blue skies below, even — you can stand at the rail and look down into nothing but clouds. The forecast is your friend.

Best time for snorkeling on Kauai
Responsible operators won’t rent you snorkel gear on days when the swell is up. Kauai’s surf is no joke — it’s the most dangerous in the Hawaiian archipelago, and the gear rental shop won’t hand you a snorkel, say thank you and visit them again the following day — they know what’s what. Typically, the swell hits the north shore in winter, the south shore in summer, so there’s always an option. The island has lovely snorkel spots on both sides — Ha’ena Beach Park, Ke’e Beach, and Anini Beach on the north end have wonderful clear waters, while Prince Kuhio, Salt Pond, and Poipu on the south are great snorkel beaches. Lydgate is especially kid friendly. The best way to find out the best time to snorkel on Kauai? Ask a lifeguard. Really.

Best time for a helicopter flight
Flightseeing over Kauai just might be the highlight of your tour. That curtain of green cliffs seen from the air, tumbling into the blue waters of the Pacific — it’s an unforgettable sight. While the weather is critical, time of day matters too. Naturally you want to fly on a clear day, if at all possible. That said, the afternoon flights are spectacular as that’s when the western face of the island is hit by the sun. You’ll get brighter, clearer views than you would in the morning, when the cliffs are in shadow because the sun is on the other side of the island.

Best time for whale watching
Humpback whales return to the warm waters around Hawaii starting in November and they stay until March — with peak time being in January. Humpbacks breed here, calve, and nurse their young, before migrating to colder waters for the summer. On Kauai, the best way to see the humpbacks is to take a whale watching cruise and get out in the water, though there are a number of land based viewpoints for whale-spotting. Shipwreck’s Beach is one, and the Kilauea Lighthouse is a designated whale sanctuary. Full disclosure, though? The Auau Channel off Maui is probably the best place to see humpbacks, with the Kohala Coast off the Big Island coming in second place. Getting out on the water really stacks your odds of meeting the humpbacks where they live. Got a land-lovers gut? Take the morning tours, you’ll have a better chance of calm waters.

Best time for fishing off Kauai
Want to make your own sushi? June, July, and August are peak yellowfin tuna months and it’s easy to find a fishing charter out of HARBOR TOWN NAME. You can pull in some variety of marlin most of of the year, with October, November, and December being the low season. Mahi Mahi peak in springtime. There’s really no bad time to go fishing; it’s all about what’s in season when you go. Charters leave from all over the south end of the island, with the bulk of them departing from the Nawiliwili Marina.
Best time to visit Queen’s Bath
This popular natural pool is so gorgeous, it’s a wonder people can’t stay away. But this is one of those attractions that may be best avoided. Kauai has some of the most rugged and unpredictable surf in all the islands and every year, lives are lost by people who either did not know this was a dangerous place, or did not observe the warnings. Skip it. There are dozens of safer places to swim, go there instead.

Best time to hang out on Kauai’s North Shore
The best weather on the north shore in late spring and early fall — the weather is good and the beaches aren’t as crowded.

Best time to explore the Na Pali Coast by water
June or July offer the best conditions to explore this rugged landscape from the water, but keep in mind, you’re on the edge of the Hawaiian archipelago and the ocean will do what it does. In shoulder seasons, May or September, the weather tends to be slightly better — meaning drier — but the swell can come up, making it hard work for kayakers and a tough ride for those who get seasick. The winds can come up any time, regardless of season, but in August there’s a slightly higher chance of hurricane weather. Most operators run May-September. When you book your tour, ask about weather cancellations.

Best time to take a tubing adventure
There are a dozen different ways to get wet on Kauai and the rain is only one of them. Doing an inner tube adventure through Lihue’s old irrigation system is a safe and fun way to get in the water and see the island from another perspective. Tours run rain or shine — you’re getting wet anyway, right? But if you get cold, take the afternoon tour; you might find the water’s warmer later in the day.

Best time to kayak the Wailua River
Since this island is so rainy, there’s no guarantee you’ll have sunshine when you paddle the river up to the famous Wailua Falls. It doesn’t matter so much what season you go, it’s time of day that’s more important. If you’re up for hard work, take the afternoon trip, you can fight the wind and the river’s gentle current. If that’s not your style, though, or your a beginner, head out as early in the day as possible. You’ll have an easier trip.
