Summer travel with horses requires extra care to prevent heat stress, which can become dangerous in high temperatures and humidity. A key safety tip is to assess weather risk by adding the air temperature (°F) and relative humidity (%). A combined value over 150 indicates reduced cooling ability, and above 180 can be life-threatening. For example, 81°F with 74% humidity equals 155—a high-risk situation. Trailers often have worse conditions due to limited ventilation and heat buildup, so installing a thermometer can help monitor internal temperatures.
To reduce risk, haul horses during cooler times of the day, such as early morning or late evening. Plan rest stops with shade and water when traveling long distances. Good ventilation is essential; open roof vents, use screened windows, remove heat-retaining plexiglass, and install fans when possible. Always protect your horse’s eyes from flying debris and never allow them to stick their head out of the trailer during transport.
