Can anyone expound on practical differences in weather in mid December versus Waikiki?
Kailua, located on the windward side of Oahu, generally experiences slightly different weather patterns compared to Waikiki, which is on the leeward side of the island. In mid-December, both areas are in Hawaii's wetter season, but the windward side typically receives more rainfall due to trade winds pushing moisture up the Koʻolau Mountains.
Temperatures in Kailua during this time are mild, averaging around 73–80°F (23–27°C) during the day and cooling slightly at night. Humidity tends to be higher than in Waikiki, but the consistent trade winds provide a comfortable breeze that helps moderate the heat.
