The 2025 summer solstice will occur on Friday, June 20, marking the longest day of the year in the Northern Hemisphere. In Honolulu, the solstice is set to take place at 4:42 p.m. local time, when the sun reaches its northernmost point above the celestial equator. The day will offer 13 hours and 28 minutes of daylight for Hawaii residents.
Astronomically, the solstice occurs when the Earth’s axial tilt is most inclined toward the sun, bringing more direct sunlight and signaling the official start of summer. Across the U.S. mainland, the sun will reach its northernmost position at 10:42 p.m. EDT.
Adding to the weekend’s celebrations is International Surfing Day, observed annually on the third Saturday of June, which falls on Saturday, June 21 this year. The day is dedicated not only to the joy and sport of surfing but also to raising awareness about the importance of protecting and preserving ocean ecosystems.
Launched in 2005, International Surfing Day encourages both seasoned surfers and newcomers to connect with the ocean while promoting environmental stewardship. Surfing, which dates back over 5,000 years, is considered by many more than a sport—it is a cultural and lifestyle movement enjoyed on every populated continent.
As Hawaii embraces both the summer solstice and International Surfing Day, locals and visitors alike are invited to celebrate the sun, sea, and sustainability.
