Best time to visit Honolulu: month by month
Short answer
Honolulu is warm all year, with highs of 25–29°C, so the best time depends on crowds and prices rather than weather. April to June and September to October are the best value, with fewer visitors and pleasant weather. Winter (December to March) is busier, with humpback whales and big waves on the North Shore.

When to avoid
Christmas to New Year and the summer school holidays are the busiest and most expensive times. If you want to swim on the North Shore, avoid winter, when waves are dangerous.
