Best Time to Visit Hawaii

Hawaii enjoys a tropical climate year-round, making it a popular destination regardless of the season. However, there are certain times of the year that may be more favorable, depending on your preferences.

• High season (December to April): This period typically sees the highest influx of tourists as visitors seek to escape the winter chill in other parts of the world. Expect crowded beaches and higher prices for accommodations and activities during this time.
• Shoulder season (May to June, September to November): Shoulder seasons offer a balance between favorable weather and fewer crowds. May and June are particularly pleasant, with warm temperatures and lower humidity. November can also be a great time to visit, as it marks the end of hurricane season.
• Low season (July to August): While summer months may see slightly warmer temperatures and higher humidity, they also coincide with school holidays, making it an ideal time for families to visit. Additionally, you may find better deals on accommodations and activities during this period.
