Oahu occupies 597 square miles and is the second oldest of the six Islands of Aloha, lying between Kauai and Maui. Oahu is made up of two major mountain ranges that were once shield volcanoes that are now extinct. These two mountain ranges – the Waianae range to the west and Koolau range to the east – run almost parallel to each other. Over a hundred ridges extend from the spines of each range creating beautiful valleys and stunning mountain vistas.
Oahu is generally drier on the Leeward Coast (west) and wetter and greener on the Windward Coast (east). The resort area of Waikiki and the surfing mecca of the North Shore offer pleasant weather year round. Big wave surf season on the North Shore begins in November and ends in February. World-class surfing competitions also happen here between November and December. During the summer, the big waves of the North Shore subside for ideal beach going conditions. There are generally two seasons on Oahu. Winter (November through April), when temperatures typically range in the low-70s to mid-80s, and summer when the high can run into the low-90s. Average air temperature ranges from 74 degrees F (23 degrees C) to 88 degrees F (31 degrees C) with moderate humidity of 53% during the day. Gentle trade winds keep even the warmest months comfortable, so any time of year is a good time to visit Oahu.
