Riding in August Heat in the Hills
August can make a Black Hills ATV or UTV ride feel much hotter than the forecast suggests. Sun, dust, engine heat, long stretches between services, and a machine that keeps moving when you are already tired can add up quickly. This guide explains how to plan a safer summer ride, manage heat on the trail, and know when to change plans or turn back.
Plan an August ride around heat and daylight
Choose your route before you unload
A route that looks manageable on a map can feel very different when you are sitting in a warm machine, breathing dust, and stopping in direct sun. Before leaving, think about the ride’s total length, elevation changes, access to shade and water, and how far you will be from a road or trailhead. A shorter loop with easy exit points may be a better choice than a longer route that leaves little room to adjust.
Start early when you can. Morning riding generally gives you a more comfortable window before the day’s heat builds, and it leaves more daylight for delays. It also gives your group time to stop, drink, check a machine, or turn around without rushing to get back after dark. If you are riding near Deadwood, Hill City, or Spearfish, avoid assuming that a cool start means the afternoon will stay comfortable.
Use a current map to understand where your planned route goes and where you can safely change direction. onX Offroad can help with route planning and orientation, particularly when you want to study an area before the ride. Download or otherwise prepare the map information you need before entering places where cell service may be limited. Digital mapping is a planning aid, not a substitute for following signs, closures, and land-manager directions.
Check trail access and conditions on the day
August is a popular month in the Black Hills, and a route that was open or passable on a previous visit may not be the right choice today. Weather, fire danger, maintenance, and temporary closures can affect where motorized riding is allowed. Check for notices before loading the machines, then look again at the trailhead or access point. A closure sign is not an invitation to find a way around it.
Make sure you understand which routes are open to your machine and whether a permit or other access requirement applies. A road and a designated motorized trail may not have the same rules. The guide to [South Dakota Trail Conditions Before You Ride] can help you build a sensible pre-ride check, while [South Dakota Trail Closures to Check First] is useful when fire or weather conditions may change access.
Maps also need to be read with care. Use official route information and signs to confirm what is open, and do not treat a line on an app as permission to travel off-route. [South Dakota Trail Maps and MVUMs] explains why map layers and land-manager information matter. If you use onX Offroad to prepare, compare what you see there with current official notices and posted signs rather than relying on one source alone.
Keep riders cooler and more alert
Hydrate before you feel thirsty
Heat can make a ride tiring before anyone recognizes that they are getting into trouble. Drink water before setting out, and keep it within easy reach during the ride. Build regular drink stops into the plan instead of waiting until someone asks to stop. On a long ride, carry more water than you expect to need, especially if the route is remote or the group includes children.
Water is important, but the practical challenge is making it easy to drink. Store bottles or a hydration system where riders can reach them safely during planned stops. Keep a backup supply in the support vehicle or another secure location if your route allows it. If someone becomes unusually weak, confused, dizzy, nauseated, or develops a severe headache, stop riding and take the situation seriously. Move them to shade, cool them, and seek medical help if symptoms are severe or do not improve.
Plan stops with shade in mind. A short break beside a shaded trailhead or a safe, permitted stopping area can be more restorative than a longer pause in full sun. Avoid blocking a route or stopping where other riders cannot see you. Let the group know in advance that anyone can call for a break; people are more likely to speak up when it is treated as normal rather than as a delay.
Dress for sun, dust, and changing conditions
Lightweight clothing that covers skin can reduce sun exposure and help protect against dust, branches, and flying debris. Wear a properly fitted helmet and eye protection, and consider gloves and sturdy footwear. A breathable layer with sun protection is often more useful than relying on sunscreen alone, but apply sunscreen to exposed skin and reapply as directed on its label. Sunglasses or tinted lenses should not interfere with visibility in changing light.
A face covering can make dusty stretches more comfortable, but it should fit securely and not interfere with safe breathing or communication. Bring an extra pair of clear lenses if your ride may continue into shade or later in the day. If you want to review the relevant riding requirements, see [South Dakota Helmet Rules for ATV Riders] and [South Dakota Eye Protection Rules for Riders]. Staying comfortable matters, but protective gear should remain in place even when the day feels hot.
Heat fatigue can show up as irritability, slower reactions, poor decisions, or a rider falling farther behind than usual. Those changes matter on a route with loose gravel, rocky sections, steep grades, or other riders coming the opposite way. Agree on a simple group check-in routine before you start: stop at planned points, confirm everyone feels okay, and make sure the last rider is still in sight or can communicate with the group.
Prepare the ATV or UTV for a hot, dusty day
Inspect the machine before the ride
A quick inspection can catch problems that are much easier to address at home than on a remote trail. Check tires for damage and suitable pressure, make sure controls and brakes work properly, and look for loose parts or visible leaks. Check the coolant and other fluids as directed in the machine’s owner manual. Do not open a hot cooling system; wait until the machine has cooled and follow the manufacturer’s instructions.
Dust can make a hard day harder on both the rider and the machine. Check the air filter before a ride and clean or service it according to the owner’s manual, particularly if the machine has been used in dusty conditions. Watch for warning lights, unusual smells, changes in engine temperature, or a loss of power. If something seems wrong, stop in a safe place and assess it rather than pushing on and hoping it clears.
For UTVs, check seat belts, doors or nets, and any required passenger protections before leaving. Secure loose gear so it cannot shift into controls or fall onto the route. Keep a small repair kit and basic first-aid supplies accessible, and make sure everyone knows where they are. A spare key, tire-repair supplies, and a charged phone or communication device can also make a difficult delay easier to manage.
Plan fuel, communication, and a safe turnaround
Heat and extra stops can extend a ride, so do not plan fuel around the shortest possible trip time. Know where fuel is available along your route and leave a reserve for detours, slow travel, or a change of plan. Do not assume that a service station will be close to every trail or road. [South Dakota Trails With Fuel Nearby] can help when comparing areas, and [South Dakota Rules for Carrying Fuel] is worth reviewing if you plan to carry extra fuel.
Cell coverage can be patchy in parts of the Hills. Tell someone where you plan to ride and when you expect to return. Keep your phone charged, but do not rely on it as your only way to navigate or get help. Mark your starting point, know the route back, and identify reasonable places to turn around. A downloaded map in onX Offroad may help with orientation where service is unavailable, but it does not guarantee that a route is open or that help can reach you quickly.
Use a simple turnaround rule before the trip begins. For example, agree that the group will head back if the temperature, rider fatigue, machine performance, or remaining daylight makes continuing a poor choice. This helps prevent the familiar trap of going “just a little farther” until returning becomes the hardest part of the day.
| August riding concern | What to do before or during the ride |
|---|---|
| Heat and fatigue | Start early, drink regularly, take shaded breaks, and turn back if someone’s condition worsens |
| Dust and visibility | Leave space between machines, wear suitable eye protection, and slow down when visibility drops |
| Fire or weather closures | Check current notices before leaving and obey signs at the route |
| Limited cell service | Share your plan, prepare maps ahead of time, and do not depend on a phone alone |
| Fuel or mechanical trouble | Inspect the machine, plan a fuel reserve, and carry basic repair and first-aid supplies |
| Afternoon delays | Keep the route realistic and preserve enough daylight to return without rushing |
Adjust your plan when conditions change
Recognize when it is time to stop
A ride does not have to end only when a machine breaks or someone becomes seriously ill. Stop and reassess if a rider is unusually quiet, struggling to keep up, making repeated mistakes, or showing signs of heat illness. Move out of direct sun if you can do so safely, give the person time to cool down, and decide whether continuing is sensible. If symptoms are severe, worsening, or include confusion or collapse, seek emergency help.
Do the same when the machine starts behaving differently. A rising temperature warning, a burning smell, loss of power, or a new mechanical noise is a reason to stop in a safe place and consult the owner’s manual or get assistance. Do not park in a blind corner or narrow section where another rider could collide with you. If the group needs to wait, choose a visible, safe location and make sure approaching traffic can see the machines.
Wind, smoke, storms, and changing visibility can also turn a comfortable ride into a risky one. Watch the sky and local notices, not just the forecast you checked before breakfast. If a storm is approaching or smoke reduces visibility, follow the safest available route back and avoid pressing on to reach a planned viewpoint or destination. A trail day is still a success when you return safely earlier than expected.
Make the return trip part of the plan
Riders often focus on getting to a scenic overlook or completing a loop and give less attention to the trip back. In August, the return can be the most tiring part if the group has spent hours in heat and dust. Check everyone’s condition before leaving a stopping point, drink water, and shorten the route if the group is fading. Do not let the desire to finish the loop outweigh what the conditions are telling you.
If you expect to return late, understand the rules for the type of route you are using and the equipment your machine needs. Do not assume that a trail suitable in daylight is safe or permitted after dark. Review [South Dakota Rules for Riding After Dark] before planning a ride that might extend into the evening. If daylight is running short, take a clear, legal route back rather than improvising a shortcut.
August riding in the Hills can be rewarding, but the best day is not necessarily the longest one. Keep the route flexible, make comfort and hydration part of the plan, and treat maps and apps as tools to support—not replace—good judgment. Checking access, watching the group, and turning around early when needed can make the difference between a memorable outing and a preventable emergency.
