Summer Heat Safety for Texas Off-Roading

How to run a hot-weather trip

A summer trip planned around the heat is safe and even pleasant. The steps below are how to keep the day on the cool side of the thermometer.

1. Start at first light and plan to be off the sand by mid-morning.
2. Carry at least a gallon of water per person, and then some.
3. Bring shade, hats and light, loose, long-sleeved clothing.
4. Check that the vehicle's cooling and air conditioning actually work.
5. Take breaks in shade and watch for signs of heat illness.
6. Save the strenuous part of the day for the cooler evening.

Spotting heat illness early

Heat problems are far easier to handle early, so learn the signs and act on them the moment they appear. Heavy sweating, weakness, headache and nausea point to heat exhaustion, which needs shade, rest and fluids right away. Confusion, a stop in sweating or fainting mean heat stroke, which is an emergency needing immediate cooling and medical help. Never leave a person alone to sleep off heat symptoms in a hot vehicle, because that is how a bad afternoon becomes a tragic one.

What cooling gear costs

Staying cool is cheap compared with a heat emergency, and the gear doubles as ordinary camping equipment. Water storage, shade and a way to chill drinks do most of the early work, with a cooler that holds ice all day as the upgrade for long summer trips. Prices vary by brand and size, so treat these as ranges.

The Valley heat calendar

The heat does not arrive and leave on a fixed schedule, but it has a shape. Late spring through early fall is the punishing stretch, with the worst afternoons at the height of summer. Even in the warm months, dawn and dusk are workable, and an unusual cool spell can open a comfortable window. The shoulder seasons are far kinder, which is why the smart Valley driver saves the long trips for the cooler months and keeps summer outings short and early.

Cooling a vehicle and a person

Heat stresses the truck as much as the driver. Check coolant and tires before a hot drive, since soft sand and hot pavement are hard on both, and watch the temperature gauge on long climbs and soft ground. For people, the rules are simple: drink before you feel thirsty, rest in shade, and never rely on a parked vehicle with the air conditioning off as shelter. On a beach or lakebed, the water can look cool and inviting while the sun and the current stay dangerous, so treat swimming with the same caution as driving.

• Check coolant and tire pressure before a hot trip
• Watch the temperature gauge on slow, soft ground
• Drink water before you feel thirsty
• Never sleep off heat symptoms in a hot truck
• Respect the water as much as the sun

Shade is the whole game

In Valley heat, shade is not a comfort; it is the difference between a long day and a dangerous one. A pop-up shelter, a tarp stretched from the truck or even a wide-brimmed hat and a long-sleeved shirt change how long a person can safely spend in the sun. Build the day around the shade you can create, move the truck to follow it and use it as a base between spells of work or driving, so the sun never gets an uninterrupted hour on you.

• Carry shade you can set up anywhere
• Follow the shade as the sun moves
• Use it as a base between tasks
• Cover skin with light, loose clothing

Working in the heat

If a recovery or a small repair has to happen in the sun, work in short bursts and rest in shade between them. Lift the hood only long enough to check or fix and then step back, drink before you feel thirsty and let someone else take a turn. Heat builds fastest when a person is fixed on a problem, so the break you think you do not need is the one that keeps you safe.
