Nighttime temperatures generally drop to the mid-60s to low 70s°F. While there is not a significant temperature difference between seasons, Kailua benefits from the cooling effects of the trade winds that sweep across the island.

The trade winds, originating from the northeast, play a crucial role in moderating temperatures and providing a refreshing breeze. These winds contribute to the comfortable climate and help disperse any heat and humidity.

Wet and Dry Seasons:

During this period, the northeast trade winds bring moisture-laden air, resulting in increased rainfall. While rain showers are frequent, they are often brief, and the sun quickly returns. The mountains on the windward side of the island contribute to orographic lifting, enhancing rainfall in certain areas.

The dry season, from April to October, sees reduced rainfall, and the weather tends to be sunnier and drier. Trade winds persist during this time, providing a consistent and pleasant climate for residents and visitors. The dry season is characterized by clear skies and a vibrant, lush landscape.

Precipitation and Rainfall:

Despite the substantial rainfall, the showers are often localized and intermittent, contributing to the lush greenery and vibrant flora that define Kailua’s landscape. The rain nourishes the diverse vegetation, including palm trees, tropical flowers, and lush foliage.
