May typically marks the transition from Hawaii’s wetter season to its drier summer months. Average temperatures range from the mid-70s to the mid-80s Fahrenheit (low- to mid-20s Celsius), providing comfortable conditions for outdoor activities. Rainfall decreases significantly compared to the preceding months, although brief showers are still possible, particularly on windward sides of the islands. Ocean temperatures are generally pleasant for swimming and other water sports.
Understanding typical climate conditions for this period is crucial for planning trips. Travelers can pack appropriately, anticipating warm days and cooler evenings. Awareness of potential rainfall allows for scheduling flexibility and consideration of alternative activities. Historically, May offers a balance between pleasant weather and fewer crowds compared to the peak summer season, making it an attractive time to visit the islands.
