St. George Heatwave Survival Guide: What Not to Do at 3PM
St. George, Utah is no stranger to heat, but when the forecast calls for the first full week of triple-digit temperatures, it’s time to adjust your routine and protect yourself. With highs expected to hover between 100°F and 104°F, staying cool isn’t just about comfort—it’s about safety.
Avoid being outdoors between 11 a.m. and 5 p.m., when the sun is at its most intense. During this window, pavement and asphalt surfaces can reach temperatures of 145°F or more. Tar used on roads begins to soften around 122°F and can melt at 140°F, turning streets into a blazing lava rivers for shoes, tires, and paws.
Inside parked cars, temperatures can climb dangerously fast. On a 100°F day, your vehicle can hit 119°F in just 10 minutes and up to 140°F within 30 minutes. Cracking windows does little to help. Never leave children or pets inside a parked car—not even for a minute. This tragedy still happens too frequently.
