Welcome to Oahu, Hawaii—If you’re planning a trip or just curious about this beautiful island, we’re here to answer three of the most commonly asked questions and more about Oahu: Where is Oahu, Hawaii? How big is Oahu? What time is it in Oahu? Let’s dive in!

Where is Oahu, Hawaii?
Oahu is one of the main Hawaiian Islands, located smack dab in the middle of the Pacific Ocean. It’s part of the United States and is the third-largest island in the Hawaiian archipelago. Oahu sits about 2,400 miles west of California and roughly 3,850 miles east of Japan.
How to Get to Oahu
Most travelers arrive via Daniel K. Inouye International Airport (HNL) in Honolulu.
Direct flights to Oahu are available from major U.S. cities like Los Angeles, New York, and Seattle, as well as international hubs such as Tokyo, Sydney, and Vancouver.
Inter-island flights make it easy to hop between Oahu and other Hawaiian islands like Maui, Big Island, and Kauai.
👉 Fun Fact: Oahu is like the Waikiki of Hawaii—it’s where everyone gathers! That’s why it’s called “The Gathering Place.”
How Big is Oahu, Hawaii?
Oahu covers about 597 square miles, making it the third-largest island in Hawaii after the Big Island and Maui. But don’t let its size fool you—Oahu is packed with stunning landscapes, exciting attractions, and endless adventures!
Oahu at a Glance:
Length: About 44 miles long (That’s like 700 football fields lined up!)
Width: About 30 miles wide (Or roughly the same as 5,280 spam musubi stacked end to end 🏝️🍙)
Highest Point: Mt. Kaʻala at 4,025 feet (That’s like stacking about 280 ukuleles on top of each other!)
Coastline: Approximately 227 miles of breathtaking beaches (That’s enough room to lay out millions of beach towels!)
👉 Fun Fact: You can drive around the whole island in 4 to 6 hours—or the time it takes to binge-watch a few episodes of your favorite Hawaiian-themed TV show!
What Time is It in Oahu, Hawaii?
Oahu, like the rest of Hawaii, follows Hawaii-Aleutian Standard Time (HAST). That means:
Oahu is 2 hours behind Pacific Standard Time (PST) (California, Oregon, Washington, etc.)
Oahu is 5 hours behind Eastern Standard Time (EST) (New York, Florida, etc.)
Oahu does NOT observe Daylight Saving Time – so while most of the U.S. changes their clocks in spring and fall, Hawaii stays the same year-round!
👉 Fun Fact: If New York is sipping its morning coffee, Oahu is still snoozing. When California hits lunchtime, we’re just rolling out of bed!
🌴 Hawaiian Time Tip: Things move a little slower in paradise—so don’t stress if events start a little late, it’s on island-time!
