. The climate is hyper-arid, extremely hot, sunny and dry year-round and there is virtually no plant life. The average high temperatures are above 40 °C (104 °F) for about 5 months and more in the hottest regions, and record high temperatures as high as 50 °C (122 °F) are highly possible during summer. The annual average high temperature is around 35 °C (95 °F). During "winter" months, the average high temperatures stay above 25 °C (77 °F) and generally hover around 30 °C (86 °F).
The annual precipitation amount is extremely low—one of the lowest annual rainfall amounts found on Earth—around 10 mm (0.39 in) to 15 mm (0.59 in), and frequently several years may pass without seeing any rainfall at all. Water is notoriously difficult to find, even underground, and wells may be hundreds of miles apart.
The sunshine duration is also one of the highest results on the planet at around 4,000 hours, that is about 91% of the daylight hours between sunrise and sunset. This part of the Sahara Desert has one of the harshest climates in the world. According to a

Landmarks
The desert is also known for the celebrated Tree of Ténéré, once thought to be among the most remote in the world. Situated by the last well before entering the Grand Erg du Bilma on the way to Fachi, salt caravans relied on the tree as a landmark until it was allegedly knocked down by a Libyan truck driver in 1973.
It was replaced by a metal sculpture and the remains are enshrined at the museum in Niamey (capital of Niger). New trees were planted but, because of the very low water table (the adjacent well is some 40m deep), irregular watering by passing travellers saw them fail to survive. Despite this unfortunate mishap, the tree is still often indicated on maps of the region as a notable landmark, as is the less well-known Arbre Perdu (Lost Tree) situated in the true Tenere to the north, west of Chirfa.
A monument to UTA Flight 772, a 200-foot diameter circle of dark stones and 170 broken mirrors which represent each victim of the 1989 terrorist attack which brought down the aircraft, was built in May and June 2007 at 16°51′53″N 11°57′13″E.
