From Locals Who Know

Let’s investigate some interesting Oahu Facts…

The Hawaiian Islands claimed title as the 50th state of the United States of A merica on August 21, 1959. My first taste of Oahu was just 3 years later when I attended 1st grade at Chester W. Nimitz School… lucky me!

To this day you can still hear US citizens visiting the islands saying t

hey are going back to the States when they go home!

Honolulu… Hawaii’s impressive state capitol… is located on Oahu Island along with world-renowned Waikiki Beach and Pearl Harbor. Honolulu is a robust city teeming with  culture and home to art galleries, museums and night life. Yet this city bustling with people and multiple high rise buildings preserves its easygoing tropical lifestyle filled with aloha spirit. 

You won’t find people living in grass huts on the island today, but you may come away wishing you owned a beach house!

Hawaii and part of Alaska’s the Aleutian Islands are in the same time zone known as Hawaii-Aleutian Standard Time or HAST which is 2 hours earlier than the US West Coast’s Pacific Standard Time (PST) and -10 UTC.

I have always heard this referred to as just HST… Hawaii Standard Time.

Hawaii does not participate in Daylight Savings Time so add 1 additional hour to the time difference when the US mainland is observing Daylight Savings Time.

Oahu Facts, Location and Terrain

Oahu Facts


The Hawaiian Island chain spans about 1500 miles beginning way out in the warm Central Pacific Ocean then proceeds northwest to Kure atoll.  The islands are recognized as the most remote islands on earth because they are further from a large land mass than any other islands.

For the purposes of this website the term Hawaiian Islands refers to the familiar 8 islands of Ni’ihau, Kaua’i, O’ahu, Moloka’i, Lana’i, Maui, Kaho’olawe and Hawai’i (Big Island).

San Francisco, California, is approximately 2400 miles Northeast of Oahu. Anchorage, Alaska, and Vancouver, British Columbia, are about 2700 miles northeast. Papeete, Tahiti,


is nearly due South at about 2700 miles, Tokyo, Japan, about 3800 miles Northwest and Sydney, Australia, more than 5000 miles southwest.


Oahu comprises approximately 600 square miles and has more than 200 miles of coastline. It is the third largest of the 8 islands.

The City and County of Honolulu includes the entire island of Oahu.


Oahu has 2 mountain ranges with a valley dividing them. The Ko’olau Mountain Range runs along the East side of the island spanning North to Southeast and the Waianae Range hugs the West side of the island running North to Southwest.

The highest point is Mount Ka’ala in the Waiainae Range at 4,003 feet. Compared to the Big Island’s Mauna Kea towering over 13,000 feet, Mount Ka’ala is relatively low.
