Kailua weather mid December

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.

Comparing Kailua to Waikiki:

  • Rainfall: Kailua sees more frequent short showers, especially in the mornings or evenings, while Waikiki tends to be drier overall.
  • Wind: Kailua is breezier due to its exposure to trade winds, making it feel cooler even on warmer days. Waikiki is more sheltered, often feeling warmer and more humid.
  • Beach conditions: Kailua beaches have gentler waves and are excellent for swimming and kayaking, while Waikiki has more consistent surf breaks popular for beginner surfers.
  • Tourist crowd: Kailua is quieter and less commercialized, whereas Waikiki can be busy with tourists and more crowded beaches.

In terms of overall weather comfort in mid-December:

  • Kailua is generally more pleasant for outdoor activities like hiking, kayaking, or beach walks due to cooler breezes.
  • Showers in Kailua can be brief and localized, so they rarely disrupt a full day of plans.
  • Waikiki's drier and sunnier conditions make it ideal if your main focus is sunbathing and urban beach experiences.

In summary, if you prefer a slightly cooler, breezier environment with occasional short showers and less crowded beaches, Kailua is a great choice. Waikiki is better suited for those wanting consistent sun, warmer conditions, and easy access to commercial amenities and nightlife.
