Recommendation
Safer morning drive: 7:00 AM–9:00 AM. Safer evening drive: 7:00 PM–8:30 PM (late evening window when temperatures begin to fall and thunderstorms are less intense, though an isolated storm is still possible). If you must drive during peak heat (roughly 12 PM–4 PM), take extra breaks, stay hydrated, and ensure your vehicle cooling system is in good condition.
