Most of East Africa is savannah, comparable to the high plateau, semi-desert areas of Colorado or New Mexico. Altitude ranges from 3,000 to 7,000 feet (915-2130 meters). (Obviously Kilimanjaro climbers will experience much higher altitudes.) Temperatures during the day range from 75 to 90 degrees Fahrenheit. Nights are cool with temperatures dipping as low as 40 degrees Fahrenheit in some areas (Ngorongoro Crater, for example). Even though you will be traveling near the equator, please take our packing recommendations seriously and take along a light jacket or sweatshirt, sweater, and a fleece pullover. Additionally, bring something warm to sleep in at night. Humidity is low. If you don't travel near the rainy season, it usually doesn't rain.
