Essential gear & clothing packing list
  • 3 Short Sleeve Shirts

Medications

If you will be taking prescribed medication while on river, please list its name and its purpose on the Registration Form. Conditions specific to Grand Canyon such as sun exposure, high temperatures, cold water immersion, etc. may affect the efficacy of your medications. Adverse reactions to medications may mimic other health concerns such as heat stroke, dehydration, etc. If we don’t know about your medications, you risk a misdiagnosis/mistreatment on-river. Please consult with your physician to determine if weather extremes or dehydration might affect you. NOTE: Bring two (2) courses of medication if you are asthmatic, have severe allergic response (e.g. to bee stings), or are using prescription medicine for any reason. Once on-river, keep one with you and give the 2nd to the trip leader.

Weather

Average Temperatures and Weather

April: Days 60–80 F/Nights 40–55 F;
May:Days 80–100 F/Nights 60–70 F;
June/July/August: Days 100–120 F/Nights 70–90 F.
Note: July/August is typically the monsoon season in Arizona which usually means a cloud buildup in the morning and short heavy rain in the afternoon.
September/October: Days 70–90 F/Nights 50–60 F.

THESE ARE NOT ABSOLUTES! It can rain in any month, or conversely, be arid and cloudless. Clouds and/or rain can cause the temperature in the Canyon’s desert environment to plummet—even during the hot summer months.

You can check these sites for weather forecasts prior to your trip:

The weather on your trip may even vary between hot and cold several times a day. Layering options are required as unexpected temperature extremes can occur at any time of year and body temperatures change with the activity (hiking in the middle of the day vs. boating early in the a.m. etc.)

It is possible, even probable, that the weather you encounter will be consistently sunny and warm/hot, but you will need to be prepared for the Canyon’s many different moods.

There is a good possibility that spring and fall rafters will experience weather conditions that lower body temperatures. During these months, if the sky is cloudy, it will result in very cold conditions while you are rafting, and “dry” gear and layering options will be required on the water.

Water Temperature

The river water temperature is ICE COLD at ALL TIMES (50–55 degrees F) – a big factor in body temperature as even the smallest waves will give you a soaking.

Travel Details

Sky Harbor Airport in Phoenix, Arizona, is the closest major airport and is about a 2.5 hour drive or a half hour flight away from Flagstaff. Most of our rafters fly into Phoenix and then fly, take a shuttle, or drive a rental car to Flagstaff.

Flagstaff By Plane

Direct flights are available into Flagstaff from Phoenix. Service from Phoenix is provided by American Airlines (aa.com/en-us/flights-from-phoenix-to-flagstaff). If you fly American Airlines into Phoenix, there is often a reduced fare on the Phoenix-Flagstaff portion.
