First Day of Summer 2025 Heatwave: How to Stay Safe and Keep Cool
The 2025 summer solstice arrives this week, and with the first day of summer comes a blistering heat wave across the US. Here are some tips for staying cool, along with a free weather app to stay informed and safe.
Heatwave a day before the First Day of Summer
A day before the first day of summer arrives, forecasters are predicting daily record highs in dozens of locations across the nation starting on Thursday, through the weekend, and into early next week. In particular, days of high 100s in the Southwest, some days above 110, even the hundred-and-teens. Much of the country east of the Rocky Mountains will see high temps in the 90s or near-100s, affecting the Plains, Mississippi Valley, the rest of the Midwest, and the Northeast, except the far northern tier, and possibly 100 in Washington, D.C., according to the Weather Channel.
The Summer Solstice: When and What It Means
The first day of summer in the Northern Hemisphere in 2025 lands on Friday, June 20. The summer solstice marks the longest day of the year, when the tilt of Earth's axis is most inclined toward the sun(about 23.5 degrees), giving us more daylight than any other day.
This astronomical event occurs when the sun reaches its highest and northernmost point in the sky, signaling the start of summer.
In 2025, the solstice officially arrives at 10:42 P.M. Eastern Daylight Time. That means:
7:42 P.M. PDT
8:42 P.M. MDT
9:42 P.M. CDT
10:42 P.M. EDT
Historically, the solstice has been celebrated as a time of renewal and abundance. But in today’s world, it can also mean the start of dangerous heatwaves, especially across the U.S., where summer temperatures are increasingly intense.
As we welcome the season of sunshine, it’s more important than ever to be mindful of rising temperatures and take proactive steps to stay cool and healthy during extreme heat.
Beat the Heat: Safety Tips for Hot Summer Days
As summer arrives, so do heatwaves that can put your health—and the health of those you love—at serious risk. Whether you're running errands, traveling, or spending time outdoors, following a few simple tips can make a significant difference in staying cool and safe.
Hydration is key. Drink plenty of water throughout the day, even if you don't feel thirsty. Avoid sugary drinks, caffeine, or alcohol, which can dehydrate you. Always carry a water bottle when you're on the go.
Dress smart. Wear lightweight, light-colored, and loose-fitting clothing. A wide-brimmed hat and sunglasses can help protect you from direct sunlight.
Stay shaded or indoors. Limit your time outside during peak sun hours (10 a.m. to 4 p.m.). If you're outdoors, find shade whenever possible and take frequent breaks to cool down.
Never leave children or pets in vehicles. Interior car temperatures can skyrocket in minutes, even if the windows are cracked. Always check the back seat before walking away.
Use fans and air conditioning. If your home doesn’t have AC, try visiting public places like libraries or shopping malls to cool off. Even a few hours in an air-conditioned environment can help prevent heat-related illnesses.
Check on vulnerable loved ones. Older adults, young children, and people with chronic health conditions are at higher risk. Make sure they have access to cooling resources and hydration.
With a bit of planning and awareness, you can enjoy the best of summer without falling victim to the heat.
