Hot Car Temperature Calculator

In a hot car, the interior temperature can increase rapidly. On a 90°F (32°C) day, it can reach 130-140°F (54-60°C), while on a cooler 74°F (23°C) day, it may still heat up to 95-105°F (35-40°C). The car’s temperature depends on factors like sunlight and insulation, so it’s vital to avoid leaving pets or people inside on hot days.
