What is the best month to visit Oahu?

The best months to visit Oahu are mid-April to early June and September to mid-December, when you usually get warm, dry weather, fewer crowds, and better prices.

September is especially appealing because it comes after the summer rush, with warm ocean temperatures and a more relaxed pace. May, September, and October tend to offer the best overall balance of weather and value.

If you are planning around activities, November to March is better for North Shore surfing, while January is the prime month for whale watching. July and August are usually the busiest and most expensive.
