Summer heat in Texas is a planning constraint, not a footnote. Interior car temperatures climb quickly; midday hiking and sealed cars are a dangerous mix.
Hard rules
- Never leave children, pets, or vulnerable adults in a parked car — not “just for a minute.”
- Lock cars and double-count passengers at every stop (habit saves lives).
- If someone shows heat illness signs, treat it as an emergency and follow current public-health / first-aid guidance.
Trip design for hot months
- Drive early; schedule indoor or shaded stops midafternoon.
- Choose swimming holes, museums, or short boardwalks over exposed ridge hikes at noon.
- Carry more water than you think you need; pack electrolytes for active days.
- Keep a sun shade, reflector, and window vents strategy for parked cars when legal/safe.
Vehicle prep
- Confirm A/C works before a long westbound day.
- Check tires and coolant; heat stresses both.
- Pack jumper kit / inflator; hot highways are bad places for underprepared cars.
- Store snacks so chocolate and medications are not baking on the dash.
