Oahu Hawaii Weather

Oahu Hawaii has a mild weather year round, thereby making it an ideal tourist destination. With an average of 20 to 29.4 degree Celsius throughout the year, the third largest island in Hawaii is warm and welcoming to visitors.

Hawaii has only two seasons – summer and winter, but it is hard to tell the difference because the weather is so similar. Winter months, which last from November to April, are only slightly cooler with more frequent rainfall. Even when such precipitation occurs, it is often brief and light. The months with the least amount of rainfall are from May to October, with June and July being the driest.

Generally, ascending to higher grounds may be cooler, wetter and mistier. It is in fact the cool north-eastern tradewinds that attracts visitors to Oahu. These winds often keep the weather on the island pleasantly comfortable. Those who intend to visit Oahu’s beaches would be pleased to know that the temperature of the coastal waters remains warm and soothing with an average of around 24.4 to 25.5 degree Celsius.

The average number of sunny days per month is about 20 days in Oahu, so it is wise to be dressed in light comfortable clothes when heading out. Also, bring your sunglasses and sun block lotion for ultraviolet ray protection. However, if you are heading up a volcano or strolling along the beach in the evening, you may want to bring a jacket because it can get colder at night.

Because the weather does not vary much, Oahu is a great place to visit year round and has many tours to choose from, such as North Shore Tours, Pearl Harbor Tours, Circle Island Tours, Dole Plantation Tours and many more. However, if you do not wish to meet crowds of beach goers, the off-seasons are from mid-April to mid-June and September to mid-December. During these periods, hotel accommodation tends to be cheaper and more attractive tour packages are offered.
