A river expedition to the Grand Canyon can be an exhilarating adventure, especially with proper preparation. You can enjoy awe-inspiring vistas of the Canyon and tackle thrilling rapids. When planned meticulously, the entire trip can be physically challenging but enjoyable.
Undoubtedly, you are already aware that a successful Grand Canyon trip requires thorough planning and research. However, one aspect that is often overlooked when preparing for a rafting trip is the temperature in the Grand Canyon. The weather in Arizona can be highly unpredictable, with temperatures soaring as high as 115°F. To ensure you make the most of your whitewater rafting adventure, it is crucial to have a well-thought-out plan to manage hot weather conditions effectively.
While privately permitted white water rafting trips are possible year-round, the commercial rafting season operates from April to October. Rafting outfitters commonly recognize that the peak season for commercial rafting trips in the Grand Canyon National Park occur during the summer months of July and August, which are known for being among the hottest of the year. Average temperatures during this time can reach as high as 100 to 105°F. Additionally, these months often coincide with the monsoon season, which can bring rain showers and clouds that provide relief from the heat.
Conversely, if you prefer to avoid the extreme heat, it is recommended to book your river trip between April and early June or from mid-September to the end of October. This allows you to enjoy cooler temperatures and avoid the monsoon season.
*Keep in mind, there are pros and cons to the different months. Shoulder season trips (April/May/Sept/Oct) with cooler temperatures may sound ideal, but one must keep in mind that the water is 45-50 degrees year-round and you'll be getting wet with buckets and buckets of water, multiple times a day. This means that 85 or even 90 degrees may not be warm enough for many who get cold easily. You can always cool down by jumping into the water, but you can't always warm up, especially if the sun has crossed past the cayon walls, and you are in shade. One advantage however is that you will likley be able to fall asleep earlier at night during shoulder season trips since it will cool faster in the evening. During the mid-summer, it may take an hour or more to fall asleep; waiting for the temperature to drop. There are some tips to helping you with the heat however, as you'll read below.
If you find yourself embarking on a white water rafting trip during the scorching summer days when the weather is at its hottest, taking precautions to beat the heat is crucial for your well-being. Here are some helpful tips to stay cool:
Despite the temptation to wear minimal clothing in hot weather, covering as much of your body as possible can actually protect you from the sun's harmful rays. The Grand Canyon's clear skies mean prolonged sun exposure, which can result in freckles, wrinkling, and discoloration of the skin. Opt for breathable clothing made of lightweight polyester with Ultraviolet Protection Factor (UPF) to shield your skin from the sun without trapping heat.
One of the perks of rafting trips is being surrounded by water. Take advantage of this by dipping your clothing, such as shirts, hats, or scarves, in water and putting them on. This simple trick can significantly reduce the impact of heat on your skin and help regulate body temperature. Some tour guides even provide lightweight sarongs that can be dipped in water and worn around the neck to prevent heat stroke during long stretches on the river.
Exposure to extreme heat can easily lead to Dehydration, causing symptoms such as dizziness, headaches, weakness, and dry mouth. Make sure to drink plenty of water during your trip, pacing yourself to drink water at regular intervals. Start hydrating even before your trip begins, and carry a water canister with you for easy access to water during the rafting excursion. Avoid alcohol during the trip as it can disrupt blood concentration, but if you do indulge, balance each drink with water to maintain stable hydration levels.
Polarized sunglasses shield your eyes by bouncing off sun rays from the water's surface. Ensure you buy one with a protective strap so you don't lose them when you encounter some Grand Canyon rapids.
Sunscreen provides dual protection for the skin through two mechanisms. Inorganic chemicals in sunscreens scatter light away from the skin, while organic chemicals absorb UV rays, preventing them from penetrating the skin. This combined action shields the skin from the harmful effects of sun exposure.
When engaging in outdoor activities such as rafting and hiking in hot weather, sunscreen is a must. Opt for a waterproof brand and generously apply it at regular intervals. Make sure to apply sunscreen in the morning before starting your day's adventure, and reapply during breaks, in between rapids, to maintain effective protection. While sunscreen may feel greasy over time, it's a small inconvenience compared to the discomfort of sunburnt skin. Prioritizing sunscreen application can help safeguard your skin from the damaging effects of prolonged sun exposure during outdoor activities.
Wearing buffs, bandanas, light gloves, and polarized glasses can provide additional protection against the sun's heat. Buffs and bandanas can be used to shield the neck from harsh sunlight, while light gloves can protect the back of the hands which are particularly susceptible to skin cancer.
Look for shaded spots along your trip, such as side canyons or areas with natural shade. During breaks or meal times, take advantage of these shaded areas to escape direct sunlight and lower your body temperature.
Wetting a towel or sarong and placing it on your camping bed before lying down can help lower your body temperature and improve sleep quality. Cooler temperatures are conducive to better sleep, and a wet paco pad or cot can help reduce body heat, making it easier to fall asleep after a hot day on the river.
If you find that tents trap heat and make sleeping uncomfortable, consider sleeping outside under the stars. This allows you to benefit from the cool air from the canyon and enjoy a restful night's sleep under the stars, immersing yourself in the outdoor experience.
At night, cool winds from the river may flow down to the land, providing a refreshing breeze. Setting up your tent as close to the river as possible can help you take advantage of these cool gusts and stay cooler during the night.
When rafting during hot weather, it's important to avoid certain things to ensure your safety and comfort:
Be cautious with your beverage choices during hot weather rafting trips. Avoid consuming excessive alcohol or other beverages that can impact your blood concentration and reaction to sun exposure. Alcohol can dehydrate you and increase your risk of heat-related illnesses, so drink plenty of water and electrolyte-rich fluids to stay hydrated.
Avoid applying sunscreen while you are under direct sunlight as it can increase your chances of sunburn. Apply sunscreen before your trip or when you are in the shade to ensure proper coverage and protection from harmful UV rays.
In conclusion, rafting during hot weather on the Colorado river in the Grand Canyon can be challenging, but with proper preparation, planning, and precautions, you can beat the heat and have a fantastic experience. Remember to stay hydrated, wear appropriate clothing, use sun protection, take breaks in shaded areas, utilize heat accessories, and set up camp strategically to stay cool. Avoid synthetic fabrics, overdoing alcolohic beverages, and applying sunscreen while under direct sunlight. By following these tips and being mindful of the hot weather, you can have a safe and enjoyable rafting trip on the Colorado River. Stay prepared, stay cool, and have a memorable adventure!
