How long is the longest day of the year in California? A solstice marks the start of summer
Get your sunscreen out, Californians. The first day of summer is Friday, June 20 — and it's also the longest day of the year thanks to the summer solstice.
The change from spring to summer is marked by the solstice, and Californians can expect a sun that will rise early and set late on June 20. As we progress through summer and approach fall in September, the days will grow shorter. The pace of our decreasing daylight will happen slowly and start to speed up toward the first day of fall, according to the Old Farmer's Almanac.
It all leads up to the shortest day of the year, which is the winter solstice and marks the start of the winter season.
So, how long is the longest day of the year? It depends on where you are in California.
We have seasons because of how Earth is tilted on its axis as it orbits the sun, said the National Oceanic and Atmospheric Administration.
'The summer solstice in the Northern Hemisphere is the exact moment each year when this region of Earth reaches its greatest possible tilt toward the sun,' according to NOAA.
The longest day of the year occurs with the summer solstice because all the sunlight we get.
You can use Time and Date to determine how many hours of daylight you'll get on June 20 by entering in your city.
For example, folks in Redding up in northern California will experience just over 15 hours of daylight. At the opposite end of the state, San Diegans will experience just over 14 hours of daylight.
Here's when the sun will rise and set across California on June 20, according to Time and Date:
Redding: The sun will rise at 5:38 a.m. and the sun will set at 8:43 p.m.
Stockton: The sun will rise at 5:42 a.m. and the sun will set at 8:30 p.m.
Salinas: The sun will rise at 5:48 a.m. and the sun will set at 8:28 p.m.
San Francisco: The sun will rise at 5:47 a.m. and the sun will set at 8:34 p.m.
Visalia: The sun will rise at 5:40 a.m. and the sun will set at 8:21 p.m.
Ventura: The sun will rise at 5:45 a.m. and the sun will set at 8:12 p.m.
Los Angeles: The sun will rise at 5:41 a.m. and the sun will set at 8:07 p.m.
San Bernardino: The sun will rise at 5:37 a.m. and the sun will set at 8:03 p.m.
Palm Springs: The sun will rise at 5:35 a.m. and the sun will set at 8 p.m.
San Diego: The sun will rise at 5:41 a.m. and the sun will set at 7:59 p.m.

What you need to know before you head to the cabin this summer when it comes to severe weather
Storms popped up quickly in and around cabin country Monday, making people activate their emergency plan where they play. It pays to have a plan in place when storms hit. "If you are at the cabin, you are in an unfamiliar spot even if you go several times of year, so you have to think about what to do if there is some kind of warning at that location just as much as you do at home," WCCO Director of Meteorology Mike Augstyniak said. Augstyniak says there are four things you need to know to keep you and your family safe when storms pop up and you are not at home. "Know where to find sturdy shelter. Mobile homes, trailers, tents, if you're camping, those are not safe in severe weather. They will not afford you any kind of protection, so think about what's nearby. If you happen to be lucky to have a cabin or home with a basement, that is the right choice. Sturdier built buildings, any interior room on the lowest level of the home will serve you well," Augstyniak said. Next, make sure you have at least two ways to receive warnings. Cell phones and apps are great — until a tower goes down. Having a NOAA weather radio that you can program to hear warnings where you are can be a lifesaver. Number three: have back up supplies on the ready. Bottled water, batteries, flashlights and lanterns are a necessity. Four: neighbors can help you stay informed during and after severe weather. "Get to know your neighbors at your cabin or where you're camping where you are staying because you can kind of form a mini safety net to help each other when the severe weather is on the way beforehand, and maybe help each other clean up if there is severe weather after it happens," Augstyniak said. Making sure you know what county you are in is key, so you can know exactly what severe weather is heading your way.

Northern Lights Alert: Here's Where Aurora Borealis May Appear Tuesday
A selection of states along the Canadian border could have a chance to see the northern lights Tuesday after a period of recent geomagnetic storms, according to the National Oceanic and Atmospheric Administration. Some geomagnetic storms pulled the northern lights to more states in recent days. NOAA forecast auroral activity with a Kp index of three on a scale of nine, suggesting the northern lights could become more active farther from the poles and be 'quite pleasing to look at' for those in the right areas. Tuesday's auroral forecast follows 'minor' geomagnetic storms that disrupted Earth's magnetic field over the last two days, increasing the Kp index to around four and boosting a chance to see the northern lights in Maine, South Dakota, New York, New Hampshire and Vermont. No minor or greater geomagnetic storms are expected through Thursday, according to NOAA's three-day forecast, with calmer auroral activity also forecast. There's a lesser chance the northern lights will be visible in parts of northeastern Washington, northern Idaho, Montana, North Dakota, Minnesota, northern Wisconsin and Upper Michigan. A higher likelihood is forecast across Canada and Alaska. (See map below.) Tuesday's view line. NOAA recommends traveling to a high vantage point away from light pollution to see the northern lights, which the agency said are best seen between 10 p.m. and 2 a.m. local time. With a smartphone, NOAA suggests enabling night mode and disabling flash, while also using a tripod to stabilize the image. If using a regular camera, photography experts told National Geographic it's best to use a wide-angle lens, an aperture or F-stop of four or less and a focus set to the furthest possible setting. Activity on the sun's surface achieved a 'solar maximum' in October 2024, meaning the northern lights could be more visible into early 2026. NOAA and NASA said this peak corresponds with an increase in solar events like solar flares and coronal mass ejections, which are responsible for the northern lights. Electrons from these events collide with oxygen and nitrogen in the Earth's atmosphere, causing them to release energy in the form of swirling lights. The strongest geomagnetic storm to reach Earth in two decades reached the atmosphere in May 2024, bringing the northern lights as far south as Florida and Texas.
