The climate of Honolulu (Hawaii - United States of America)
Honolulu is the capital of the state of Hawaii. The city is located in the southeastern part of the island of Oahu, which is one of the most important tourist destinations. Honolulu is mostly known for the Waikiki suburb. Along the narrow Waikiki Beach many high rise hotels can be found. Mainly American citizens spend their vacation here. Almost half of all tourists that visit Hawaii stay in one of the hotels in this area which only has a surface area of 4 square kilometers which is filled with hotels, shopping malls, restaurants and bars. If you want to experience the authentic Hawaiian atmosphere Honolulu is not the right place. A population of almost 400,000, high rise buildings and congested highways are not conducive to a blissful atmosphere. About 11 kilometers to the west of Honolulu the American Naval base Pearl Harbor can be found which was attacked by the Japanese on 7 December 1941 causing America to get involved in WWII.
Because of the geographical location of Honolulu on the island of Oahu the city has a tropical savannah climate with low precipitation figures. Honolulu can record 500 millimeters of annual precipitation. On average Honolulu gets 98 days of precipitation per year. Winters are slightly wetter than summers. However, there is no distinct rainy season. During the day temperatures in Honolulu are between 27-31 degrees Celsius (80-88 degrees Fahrenheit). During the night temperatures are between 18-24 degrees Celsius (65-75 degrees Fahrenheit). Because of an ever blowing trade wind humidity figures remain relatively low compared to other tropical destinations. In January the average humidity figure is 82%. However, during the summer this percentage drops to 75%.

More climate information
Climate figures are very useful but dont present a general impression of the climate and the eventual weather circumstances within a certain period. The figures dont always reflect the chance of wintry weather, extreme heat or hurricanes. That is why we offer useful extra climate information for each month of the year:
