When to Go
The best time to visit Kauai
When to go to Kauai for the driest weather, the calmest water, and the fewest crowds, and why the shoulder seasons quietly win on the Garden Isle.
The short answer
The best time to visit Kauai is the shoulder seasons, roughly April to early June and September to October, for warm, drier weather and lower rates. Winter is greener and wetter, especially on the north shore, and summer is busy, sunny, and beautiful.
Kauai is the greenest of the main islands, and that green comes from rain. Timing a visit here is really about chasing the drier, warmer windows while still catching the island at its lush best.
Shoulder seasons (April to June, September to October): the sweet spot
These months bring warm, mostly dry weather, smaller crowds, and the lowest luxury rates of the year. The island is still green from the winter rains but the skies are clearer, which makes it the best all-round time to go.
Winter (November to March): green and dramatic
Winter is the wet season, especially on the lush north shore, with bigger surf and the occasional passing storm. It is also when the island is at its most vividly green, and when the whales arrive offshore. Pack for a shower or two and you will be rewarded.
Summer (June to August): warm and lively
Summer is warm, sunny, and busy, with calm north-shore water that is off-limits in winter. It is a beautiful time to visit if you plan around the crowds and book the best stays early.
On Kauai a little rain is the price of all that green, and the shoulder seasons are where the two make their best bargain.
