FAQs about flying to O'ahu
O'ahu climate
Seasonal climate doesn’t really exist here. As with most of Hawaii’s islands, the weather is inviting all year round. With temperatures always ranging between 21-27 degrees, there’s no bad time to book a flight to Oahu, especially if you’re looking to escape winter blues. Humidity spikes a bit in the summertime (April to October), but not unbearably. November to March bring more rain than any other time of the year, and the Kona winds come in through the mountain ranges to cool things down.

The easiest way to get around Oahu is by renting a car. The rental car companies have shuttles at the airport’s arrival gate that will take you straight to pick up your car. Buses are labelled “TheBus” and are easy to use, running all over the island. There are schedules posted at every stop.
