2025 Events and Festivities
If you’re lucky enough to find yourself on Oʻahu this September, you’re in for a treat. The island really comes alive in the fall with a mix of cultural celebrations, high-energy sporting events, and soulful music that takes full advantage of the warm nights. September is a sweet spot for visiting, with summer crowds easing, tradewinds steady, and the festival season in full swing. Whether you’re drawn to traditional Hawaiian culture, live music under the stars, or athletic feats across land and sea, Oʻahu has something happening this month that you won’t want to miss. Let’s take a look at the most popular events lighting up the island this September.
Aloha Festivals
The Aloha Festivals are the crown jewel of Hawaiʻi’s cultural celebrations and the biggest of their kind in the state. Founded in 1946, this month-long series of events honors Hawaiʻi’s heritage through music, dance, food, and parades. The season begins with the Royal Court Investiture and Opening Ceremony at ʻIolani Palace, where Ali‘i (royalty) in regalia are presented. The biggest highlight is the Waikīkī Hoʻolauleʻa, a huge block party along Kalākaua Avenue where local musicians perform, hula dancers fill the streets, and food vendors serve ono (delicious) Hawaiian eats. The grand finale is the Floral Parade, featuring flower-covered floats, marching bands, and paʻu riders on horseback draped in island blooms. Free and family-friendly, this is where the spirit of aloha shines brightest.
