Best Time Of Year To Visit Kauai

Between September and November, or April and June, is the best time of year to go to Kauai because the weather is good and flight and hotel rates are lower.

The rainy season, which runs from December to March, doesn’t stop people from searching for a winter break, but be aware that hotels and flights will be more expensive during this time.

If the winter months are too expensive for you, consider the spring and fall seasons as a compromise.

After the peak season ends and families leave for their summer vacations, rates on Kauai drop slightly. Summer vacations on Kauai won’t be as expensive as winter vacations, but they won’t be cheap either.
