Given Honolulu’s tropic position on Oahu you will find it to be a vacation destination close to heaven on earth - it is never too hot and never too cold - all year round! The sun is out every single day and a beautiful breeze also helps it to never feel too hot. In summer temperatures hobble around in the 80s F and even in winter they rarely drop under the 70s F.
If you are looking for times with fewer visitors and lower prices check out the months from the second half of April to early June as well as the months from September until early December. In the peak season from late June to August it’s busier given the school holidays and drier season with less rain which visitors aim to enjoy. In the winter months from mid December until April, many surfers do visit to enjoy the stronger trade winds and visit the diverse surf events.

Things to know about Honolulu - Oahu

Honolulu is the capital of Hawaii and situated on the island of Oahu. Hawaii is made up of six islands (Oahu, Kauai, Maui, Hawaii, Molokai and Lanai) located in the Pacific Ocean. Honolulu is Hawaiian and basically means ‘sheltered bay’. Honolulu has a population of 390,000 and is the only real big city on any of the Hawaiian islands. Honolulu is an exciting place to be - there is lots going on from Chinatown to Waikiki Beach. If you are after a more relaxing and peaceful location for your vacation, other parts of the island of Oahu would be recommended.

Honolulu offers everything a big US city can - from skyscrapers and lots of traffic to art and culture. The big advantage is its location in the Pacific Ocean. You can spend half of the day on Waikiki Beach and then go exploring.
