- Eight-hour average of sunshine in winter, and ten hours in summer at Doha International Airport in 2015. 
The sun is perpendicular over a large part of Doha International Airport which receives a great deal of sunlight. The key factors behind these high temperatures consist in the continental location, sky clarity, and absence of vegetation. The sun’s vertical rays increase in summer during the entire period when the day is long, which in turn leads to a high rise in temperatures. In Summer for example the day length attains approximately 10 hours on average, and roughly 8 hours in winter when teperatures are low.
