This is a subjective question.  We are unable to predict the weather at any given time as the weatehr of the Hawaiian Islands is very unpredictable.  It has been our experience, however, that during the winter months (November to March) it is generally wetter than during the other months of the year.  Being on an island surrounded by open ocean the weather can change suddenly and unexpectedly.  If you want historical weather data, please visit www.weather.com and use our zip code of 96717 for more information.
