Anytime of year is a good time to visit Hawaii. Summer, between April and November, is warmer and drier (average temperature is 75˚-88˚ F) while winter, between December and March, is a bit cooler (68˚-80˚ F). Trade winds keep things comfortable year-round. The ocean temperature is 71-81˚F year round.
What to Pack to Hawaii
Unless you want to dress up, leave your coat and tie in your closet at home.
Dress for comfort and pack your t-shirts, tank tops, swimwear, shorts, jeans, sneakers, and sandals!
Temperatures are cooler in the evening, but not cold enough for mint coats or winter wear.
Attire is “resort wear” or “Aloha attire” even at the most luxurious resorts and restaurants.
Get into the local scene by wearing a Aloha shirt or commonly referred to as a Hawaiian shirt.
Semi-formal functions in Hawaii such as weddings, birthday parties, and dinners are often designated as “Aloha Attire”, meaning that men wear Aloha shirts and women wear “muumuu” or other tropical prints.
