How to Keep Cool on a Summer Road Trip

A summer road trip sounds breezy until hour three, when the AC is losing a fight with the afternoon sun, the back of your shirt is glued to the seat, and the kids in the back are melting down along with everything else. A car left in the sun turns into an oven fast, and long stretches of highway with the light pouring through the glass wear you down even with the air conditioning running. Here is how to stay cool on a road trip so the drive is part of the fun instead of the part you survive.

Pre-Cool the Car and Park Smart

Start every leg by getting the trapped heat out before you climb in. A car left in the sun can get brutally hot inside, so open the doors for a minute and let the oven air escape, then run the AC on fresh air rather than recirculating that first blast of hot cabin air. A sunshade across the windshield while you are parked keeps the dashboard and wheel from turning into a heat source in the first place. When you stop along the way, hunt for shade or park so the windshield faces away from the sun. A few seconds of planning at each stop saves you ten minutes of suffering when you get back in.

Help Your AC Keep Up

Car air conditioning has limits on a 95-degree day, so give it a hand. Crack the windows for the first minute of driving to push the hottest air out, then close them and let the system do its job. Use recirculate once the cabin has cooled, since it is easier to chill already-cool air than to fight the heat outside. Point the vents up toward your face and chest, where the cool air does the most good. If you are driving an older car or the AC is weak, a clip-on 12-volt fan aimed at the back seat helps the people who never get enough airflow. Tinted windows and the mesh sunshades that cling to the side glass cut the radiant heat on long sunny stretches.

Hydrate on the Road

It is easy to skip water on a drive because you do not want to stop, but that is exactly how you arrive cranky, headachy, and drained. Keep a cooler of cold water within reach and sip steadily instead of rationing it to dodge bathroom breaks. Frozen water bottles do double duty here, keeping the cooler cold and turning into ice water as the day goes on. Go easy on the gas-station energy drinks and heavy sodas, which do not hydrate you the way water does. If it is a long, hot haul, drop in an electrolyte tablet now and then, especially after you have been in and out of the heat at stops.

Take Real Breaks Out of the Car

Pushing straight through to make time backfires in the heat. Stop every couple of hours, get out, and move in the shade for a few minutes to let your body reset. A rest area with trees, a shaded gas station canopy, or a quick walk around a cool store all break up the slow bake of a long drive. Stretching your legs also keeps you alert, which matters as much as comfort when you are the one behind the wheel. Use the stops to top off the cooler with ice and re-chill anything that needs it before the next leg.

Watch the Back Seat, Kids, and Pets

The back seat is almost always hotter than the front, and it is where the kids and the dog usually ride. Direct sun through the rear windows hits them hardest, so put mesh shades on the back glass and check on them more often than you think you need to. Never leave a child or a pet in a parked car even for a minute in summer, since the temperature inside climbs to dangerous levels shockingly fast. Dress kids in light layers, keep their water within reach, and watch for the flushed, drained, cranky look that means they are overheating. A handheld or clip fan in the back goes a long way toward keeping the peace.

Cooling You Can Wear While You Drive

The trick to staying comfortable for hours in a hot car is cooling you can wear without it getting in the way of driving. A cooling neck ring is a soft loop you chill and wear around your neck, and it sits comfortably under a seatbelt without bothering your hands or your view of the road. It is hands-free, has no batteries and nothing to charge, and does not drip or leave condensation on your seat, so it will not leave you sitting in a wet patch.

A road trip makes recharging it easy. The gel firms up when it meets anything colder than about 64°F, so freeze it overnight at the hotel and it is ready for the morning drive, or chill it in roughly 20 minutes in any freezer, about 10 minutes in cold tap water at a rest stop, or right under the car's AC vent while you drive. A charge lasts somewhere around one to two hours depending on how hot the car gets, and you can keep a spare in the cooler with the frozen bottles and swap to the cold one at your next stop. It feels cool rather than ice-cold and cannot get cold enough to cause frostbite, so it is comfortable for the driver and easy to hand to a kid in the back. It will not lower your core body temperature, but it takes the edge off the heat and keeps you comfortable mile after mile, which helps you stay alert on a long sunny drive.

Your Road-Trip Cooling Checklist

Staying cool on a long drive comes down to a few habits and a little gear. Stack them and the miles stop wearing you out. The short version:

• Air out the car before each leg and use a windshield sunshade when parked
• Help the AC with cracked windows at first, then recirculate, vents up
• Keep a cooler of cold water in reach and sip steadily
• Stop every couple of hours to move in the shade and re-ice the cooler
• Shade the back windows and check on kids and pets often
• Freeze a cooling neck ring at the hotel and wear it as you drive

Get the car cooled down, keep water close, and slip on a cooling neck ring before you pull out, and a summer road trip goes back to being the good part of the vacation. Drive the miles, not the misery.
