The Summer Solstice: The Longest Day of the Year in the Northern Hemisphere

CliffordSci/Tech2025-06-204500

The summer solstice is here! Friday marks the start of the longest day of the year for those living in the Northern Hemisphere, according to the Old Farmer’s Almanac. During this time, the sun will reach its northernmost point in the sky, giving us more daylight hours and later sunsets.

The tilt of Earth’s axis is the reason for this phenomenon. Normally, the sun does not rise and set in the same place on the horizon due to this tilt. However, during the solstice, the sun’s apparent path does not change for some time, making it appear higher in the sky and stay out longer.

In San Diego, solar noon is expected to happen at 12:50 p.m., with the sun rising at 5:41 a.m. and setting at 7:59 p.m. This gives us 14 hours, 18 minutes, and 26 seconds of daylight. After Friday, the sun will set later and later in the evening, with the last 8 p.m. sunset on July 5. After that, the sun will begin to set a few minutes earlier each evening.

It's important to be prepared for potential challenges during this season of longer days and later sunsets. Increased wildfire risk and heat-related illnesses are just a few of the challenges we may face. Make sure to stay hydrated, wear light-colored and loose-fitting clothing, and avoid being outdoors during peak heat hours.

As we enter this special time of year, it's also important to take advantage of the extra daylight hours by getting outside and enjoying all that summer has to offer. From hiking in the mountains to spending time at the beach, there are endless opportunities to make the most of this special day.
