Best Times to Visit Kauai
The best time to visit Kauai is between September and November or from April to June, when the weather is pleasant and airfare and hotel rates drop. Rain from December to March doesn't deter visitors looking for a winter getaway, but a word to the wise: You'll face the highest markup on rooms and flights if you visit at this time. If the fall is out of the question and the winter is just too pricey, consider the spring months as a compromise: Kauai sees a slight dip in prices after the peak season concludes and before families take summer vacations.
Fall room rates dip below $150 at many hotels, and average temperatures are in the low 70s and 80s. You'll also avoid crowds at this time of year.
Most people travel to Kauai during this chilly season, but this is when the island experiences the worst weather. Average precipitation is fairly high, particularly in December. Book several weeks to months in advance if you want a winter vacation; some four-star hotels advertise rooms for more than $500 a night.
Kauai weather is picture perfect in spring and — shhh! — so is the airfare. But it's best to get your vacation in early, before school lets out.
Kauai hotels spike their prices just in time for family vacations; keep that in mind if you're itching for a summer trip, and book several months in advance.
